Evaluation of U.S. Pet Microchip Scanning Network Microchip Readers

December 15, 2007

Los Angeles, CA. --
For the past twenty years, TROVAN, AVID and Destron (aka DigitalAngel/HomeAgain) microchips have been used to identify pets and companion animals in the U.S. By 1993, animal control agencies, humane organizations and other pet welfare organizations recognized that a microchip incompatibility problem existed: the different microchips could not be "cross read" by the readers being provided. AIM USA took the lead in establishing and coordinating a forum of manufacturers, animal shelter organizations, humane societies and veterinary professional organizations to establish requirements for a reader standard to ensure cross compatibility in the reading of the various microchip types. The requirements were published in December 1994 and were to become the basis of the so-called "American standard."

The need for a true universal reader that works well on all the microchips in the installed base is as compelling now as it has ever been. A new comparative reader evaluation demonstrates the reason for the alarming number of reports of deficiencies in the pet microchip scanning network in the U.S. The problem has been further aggravated by the recent introduction and growing dependence of shelters on the Black Label Reader.Click here.

The first chart, entitled "U.S. Pet Scanners--Performance Evaluation," summarizes the results of the reader evaluation. Subsequent pages provide a brief description of the readers examined and a detailed reading performance evaluation of each reader on each microchip type. The AVID PowerTracker Reader (which reads all the microchip types in the U.S. installed base) is not included in the evaluation because of unavailabilty and because it has been made available by AVID only selectively to some animal control agencies.
Two of these readers are targeted specifically at vets or breeders (LID-560 and Destron Pocket Reader). The others are being marketed to vets, but also aggressively distributed to shelters, as readers "of last resort" for use in life and death situations to determine whether a recovered animal has a chip and therefore an owner. One of these has been restricted to read only certain transponder protocols for business purposes. And one (Black Label), which is being marketed as a multi-system reader, has an unacceptably short read range for several chips in the U.S. installed base and will almost certainly result in false no-reads in critical life and death situations.

Field experience with the Black Label reader, which the attached study does not show, is that the Black Label reader will on occasion mismatch the code number detected with an incorrect manufacturer or display an incorrect code number.

The LID-560 reader displays the text “CHIP DETECTED” rather than the full code number when an FDX-B transponder is present. This is being done for legal reasons. The legality of use, marketing and sales of the FDX-B (ISO) transponders which operate on 134.2 kHz is currently being litigated in the United States federal court system in three jurisdictions [Marshall, TX, Case #2:04-cv 183(TJW), Riverside, CA, Case #5:06-cv-01109-SGL-OP, New York, NY Case #06-cv-4476(VM)] by patent owners claiming that certain multi-system readers and FDX-B transponders infringe on total of five patents.

Open letter by Joseph V. Masin, President of EID Systems, Ltd. to Hannis Stoddard, President of AVID Identification Systems, Inc. inviting AVID to participate in act of public service

December 14, 2007

Los Angeles, CA. --

AVID Identification Systems, Inc.
Hannis Stoddard, President

Dear Hannis,

This is to renew our standing offer which we have made in March 1992 to Avid to license the Trovan patented communication protocol between Trovan transponders and readers to Avid for the price of $1.00 (one dollar).

As you know, the owners of companion animals and U.S. animal welfare organizations require all readers used in the market to correctly display the code number and the manufacturer of the animal for the purpose of reuniting pets with their owners and saving lives of animals.

This requirement has been stated in the AIM Companion Animal Electronic ID User Requirements document dated 12/6/1994 in the creation of which AVID participated. The document lays the ground work for the "American Standard", specifying the three transponder protocols present in the market (Avid, Destron, and Trovan, currently distributed by AKC/CAR).

The implementation of the Trovan communication protocol in all your readers would benefit the public in general and allow you to demonstrate Avid's dedication to animal welfare, preventing unnecessary euthanasia of countless animals.

AVID President Misleads Public

October 15, 2007

Los Angeles, CA. --

This letter is to address certain statements made by Dr. Hannis Stoddard, President of AVID, in his continuing efforts to protect his microchip business. (see NACA NEWS, September/October 2007)

Recent comments made by Dr. Stoddard regarding the TROVAN microchip being sold by AKC Companion Animal Recovery are misleading and in certain cases factually not true.

For instance, he states that there is a permanent injunction in place in the US …..against any person for ……. selling any TROVAN microchip (TROVAN ID -100 transponder). What he fails to tell you is that the TROVAN product being sold and marketed by AKC CAR and manufactured by TROVAN is the TROVAN ID 100US transponder with lancet which has no such injunction and is non-infringing. Dr. Stoddard is well aware of this.

This is no accident. In a recent court ruling in Texas dated September 28, 2007 where AVID and another chip manufacturer (not TROVAN) have been in dispute the Judge made the following comments regarding AVID and Dr. Stoddard. “The court finds Dr. Hannis Stoddard’s trial and deposition testimony is simply not credible on key issues. This finding flows from Stoddard’s conspicuous inability to recall facts while testifying, combined with his refusal to acknowledge incontrovertible events.” The court goes on to say “that AVID intentionally withheld information from the PTO in an effort to deceive the PTO and obtain allowance of the ‘326’ patent.” Click here.

Dr. Stoddard presents a genuine problem that exists with the microchip scanning network in the U.S. today. That problem is that any veterinary practice, animal shelter, or law enforcement agency that depends on the AVID MiniTracker Scanner to protect the hundreds of thousands of pets that have been identified with the Trovan microchip since 1991, and an undetermined number of ISO microchip implanted pets, is putting the safety and well being of those pets in real jeopardy.

Scanners can excite and read chips that operate at125kHz, 128kHz and 134kHz. The idea that 128 kHz is incompatible with125kHz is a result of AVID manufacturing scanners to NOT read other chips apart from their own and Home Again. And this despite the fact that TROVAN microchips have been identifying American pets since the early 1990s. The example Mr. Stoddard used as an argument against TROVAN/AKC microchips in the market is actually not even a Trovan microchip, but an Allflex clone of the HomeAgain microchip. This year 20,000 scanners have been issued by Bayer, plus 30,000 Home Again Scanners will be retrofitted and provided in the US market announced by Home Again at the AVMA conference in Washington DC and all these scanners can and will read chips that operate at 125kHz, 128kHz and 134kHz.

There is growing recognition by most US entities that the US needs and deserves a microchip and recovery system that is truly universal and not captive to the business interests of one manufacturer, consequently putting some microchipped pets at risk.

Trovan strongly recommends that any entity in the current pet microchip scanning network that is relying on the AVID MiniTracker reader to immediately contact the AKC for an upgrade so they can adequately protect all microchipped pets.

Trovan recognized in the early nineties the need for readers that provided true universality in reading, with performance that does not arbitrarily discriminate for “business” purposes. Subsequently, AVID refused to make its encryption scheme available to other companies. Trovan has independently developed a capacity to read and correctly display AVID encrypted microchips in the readers it distributes, and has continued its devotion of resources toward this universal reader goal, expanding the microchip types detected to include ISO types of microchips. It has embodied this capability into its AKC CAR pocket reader (LID-560) and its shelter reader (GR-251).

If anyone has any questions please do not hesitate to contact me.

American Kennel Club Companion Animal Recovery (AKC CAR) and Electronic ID Devices, Ltd. (EID), announce partnership

February 20, 2007

Las Vegas, NV--
AKC, Companion Animal Recovery (AKC CAR) and Electronic ID Devices, Ltd. (EID), distributors of TROVAN® microchips in the United States, have announced their decision to form a partnership to serve American pet owners and their pets with complete identification and recovery services. AKC CAR, located in Raleigh, NC, was founded in 1995 as a not-for-profit organization managing a 24/7 recovery service for companion animals. It is the largest not-for-profit recovery service provider, storing over 3.5 million enrollment records and reuniting over 315,000 lost pets with their owners.

Through its distribution agreement with EID, AKC CAR has become the exclusive distributor of TROVAN® microchips in the United States companion animal market. The decision to partner with Trovan adds the distribution of TROVAN® transponders (microchips) to AKC CAR's services.

TROVAN® transponders were selected by AKC CAR because of their advanced technology and unmatched performance in this product category, in this application today. TROVAN® transponders have been in production since 1991, using the most modern operational and manufacturing technologies available. Trovan developed the direct bonding "must have" technology for the manufacture of transponders, eliminating superfluous components and increasing product reliability, and was first to offer a functioning single panel "walk by" reader for high traffic animal shelters.

TROVAN® transponders, together with Home Again and AVID, are part of the American standard, complying with the installed reader base used for identifying lost microchipped animals in animal shelters throughout the United States.

"We are pleased to announce the decision by American Kennel Club Companion Animal Registry to partner with our company and AKC CAR's decision to expand their activities beyond the operation of their registry and database," said Mr. Joseph Masin, President of EID. "AKC CAR has been sucessfully providing a public service since 1995, helping to reunite lost pets with their owners. Together with AKC CAR, we are dedicated to providing the best combination of hardware and service to the pubic available anywhere."

AKC CAR and EID are dedicated to responsible pet ownership and believe that by partnering they can reduce the cost of microchipping in the U.S. and increase the number of lost pets that are recovered. The American RFID standard is supported by multi-system readers distributed by HomeAgain® /Schering Plough, Avid® and TROVAN®.

National Companion Animal Organization Voices Opposition to Microchip Rule That Would Endanger the Lives of Millions of American Pets


September 1, 2006

Nashville, TN--
The American Microchip Advisory Council for Animals (AMACA), composed of professional animal care givers, veterinarians and microchip user groups has voiced opposition to a proposed rule by the USDA, which would require the use of a microchip that is incompatible with the system used in the United States.

"This could adversely affect millions of American pets that have been microchipped or will be microchipped in the future", says AMACA member veterinarian, Dr. Philip Wagenknecht.

The Council represents the interests of companion animal and horse owners by offering an electronic forum at for user groups who depend upon the extensive microchip recovery system in the United States. The tiny rice-sized microchip is used in millions of pets and horses and can save the life of an animal lost or displaced after a disaster or one who simply wanders from home.

Many shelters and rescue organizations microchip 100% of pets adopted, and thousands of veterinarians offer the service to their clients. More than 1200 calls each day are placed by veterinary hospitals, humane societies, rescues, animal control and other AMACA members who are using the microchip number to reunite pets with their owners.

Microchip numbers are maintained in pet recovery databases that work together to provide the information necessary for animal care providers to quickly reunite lost or displaced pets with their families, 24 hours a day, every day of the year.

The identification system has grown rapidly since 1996 when microchip manufacturers complied with compatibility requests from veterinary and shelter organizations. Since that time, scanners used in recovery efforts have been able to read all chips used in America, regardless of manufacturer.

In the wake of numerous disasters such as Katrina, the California wildfires, east coast floods, and heartland tornadoes, AMACA has become the 'Voice for Microchip Users' who want to safeguard and enhance the system so many now depend upon.

AMACA members form the infrastructure of the current practice of microchipping pets and horses in this country. The organization has voiced opposition to a proposed rule that is being considered by USDA, set out in APHIS Docket 2006-0012. This proposed rule would require an incompatible change in the microchip frequency in America.

New U.S. Companion Animal Registry Makes Debut


December 27, 2004

As of the beginning of 2005, Schering Plough’s Home Again will operate its own companion animal registry. Home Again has until recently been closely associated with the AKC CAR (America Kennel Club Companion Animal Registry), which in the past received most of their new income-producing registrations from Home Again customers. In future Home Again customers will be supported by Schering Plough’s own database.

The United States are home to some 120 million companion animals. Major suppliers of microchips in the United States are: AVID, Schering Plough/Home Again and Trovan.

A recent effort to introduce the so-called ISO standard identification chip to the United States failed on several well-publicized legal and practical hurdles.

1. The ISO-type microchips cannot be detected by the installed reader base in the United States, which will detect only Home Again 125-KHz, AVID “encrypted” and Trovan 128-KHz chips. In at least one documented instance, pets identified with ISO chips have been euthanized because they were not detected by the readers in use in U.S. animal shelters, which were in many instances placed there by manufacturers at no cost to the shelter.

2. The ISO microchips and some compatible readers have been determined to be in conflict with intellectual property rights of third parties by U.S. courts, or are still being litigated.

3. The ISO 11784/85 standard is an open standard and does not assure unique ID codes (see The Controversial ISO 11784 / ISO 11785 Standard here).

The four microchip registries operating in the United States are:
1. AKC CAR 1-800-252-7894
2. InfoPet Identification Systems 1-800-463-0738
3. AVID PETTRAC 1-800-652-9977
4. Schering Plough 1-800-521-5767

New European Pet Passport Law Calls for Transponder ID


July 3, 2004

Brussels --
The European Union has implemented new legislation governing the import of pet animals into member nations.
Regulation (EC) No 998/2003 of 26 May 2003, entitled “On animal health requirements applicable to the non-commercial movement of pet animals and amending Council Directive 92/65/EEC,” entered into force on 3 July 2004. It stipulates that pet animals entering member nations be provided with a “pet passport” to clearly determine its identity, proof of vaccination and positive ID.
For an eight year transitional period, this positive ID may be either a tattoo or electronic ID (transponder.) Article 4 of the law stipulates that transponders must “comply with ISO Standard 11784 or Annex A to ISO Standard 11785.”
In other words, complying transponders are those commonly known as:
HDX-B (not suitable for use in cats and dogs)
Trovan 128 Khz
Destron 125 Khz, or ‘FECAVA” or “FDX-A”
Datamars 125 Khz
Of these, only Trovan 128 Khz and Destron 125 Khz have significant installed bases in countries affected by the law (non-member nations).
Other transponders may be used, but in that case the pet owner must furnish a compatible reader at his own cost.
After the transitional period, only the transponder specified in Article 4.1 may be used.

Banfield The Pet Hospital stops marketing ISO microchip

May 14, 2004

A spokesperson for Banfield The Pet Hospital, which has locations in PetSmart stores throughout the United States, has confirmed that the company has stopped marketing their ISO FDX-B microchips.

On April 21, a pit bull was euthanized in a Virginia shelter, because the animal’s Banfield-supplied chip was not compatible with the shelter’s reader. Inquiries by journalists confirmed that none of the area’s shelters was using compatible readers.

Mark Kumpf, President of the Virginia AnimalControl Association, said: “HSUS, ASPCA, NACA, and other national animal care and control organizations have issued a warning to pet owners that new ISO microchips offered by Banfield and other pet hospitals may place your pets at risk.” Rick Collord, Former Chairman, Society of Animal Welfare Administrators, Microchip Committee, explained that “With the use of this incompatible technology, and without scanners in widespread use that can read all three chips accurately, thoroughly and precisely, the new ISO chip is a detriment."

Dr. Jamie Rees of Banfield stated that “Banfield has chosen the new ISO chip and scanner because it is the new technology that is what the rest of the world is using.”

Although ISO FDX-B microchips are being used in some European countries and parts of Australia, acceptance of ISO FDX-B microchips is not universal and the standard on which they are based continues to generate controversy, in part due to concerns about ID code duplication.

TROVAN Products Are FDA Approved

June 21, 1999

Santa Barbara, CA--
Electronic Identification Devices, Ltd. confirmed today that its TROVAN ZIPQUILLTM Implantable Delivery Device is approved for implantation of a transponder in food animals. In his letter dated 8 May, 1998, George Graber PhD, Director Division of Animal Feeds, Center for Veterinary Medicine, confirmed that "We have reviewed your submission and find there are no human food safety concerns."

The ID-100 TROVAN implantable transponder was previously approved on February 15, 1996.

"We are very pleased that our TROVAN ZIPQUILLTM has been approved for use in animals. We are now actively seeking marketing partners for this exciting new product in the areas of animal and human pharmaceutical applications," Mr. Joseph Masin, President of Electronic Identification Devices, Ltd. said.

The TROVAN ZIPQUILLTM is a unique transponder delivery device which consists of a tiny container shaped like a bullet, which tapers to a sharp point. Inside is an ID-100A transponder. The TROVAN ZIPQUILLTM can also be used to deliver antibiotics and other pharmaceutical compounds. The TROVAN ZIPQUILLTM can be inserted very easily simply by pressing it, sharp point first, into the animal's skin with the thumb. No tools are necessary.

The TROVAN ZIPQUILLTM does not make an incision, or cut, in the skin as a syringe would. Rather it pierces the skin, allowing for rapid closure of the opening after penetration of the TROVAN ZIPQUILLTM, thereby minimising tissue damage and trauma.

Trovan, Ltd. Introduces Revolutionary Delivery Device for Animal ID

October 21, 1997

Santa Barbara, CA--
Electronic Identification Devices, Ltd., the North American distributor for TROVAN, LTD. is pleased to announce the introduction of the new TROVAN ID-100ZIP animal identification transponder. The ID-100ZIP features the patented TROVAN ZIP QuillTM.

The TROVAN ZIP QuillTM is a unique transponder delivery device which consists of a tiny container shaped like a bullet, which tapers to a sharp point. Inside is an ID-100 transponder. The TROVAN ZIP QuillTM can be inserted very easily simply by pressing it, sharp point first, into the animal's skin with the thumb. No tools are necessary.

The TROVAN ZIP QuillTM does not make an incision, or cut, in the skin as a syringe would. Rather it pierces the skin, allowing for rapid closure of the opening after penetration of the TROVAN ZIP QuillTM thereby minimising tissue damage and trauma.

"To the uninitiated," said Mr. Dieter Salomon of Trovan, Ltd., "the TROVAN ZIP QuillTM may look like it is made of a very hard, clear plastic, but the "plastic" is actually a soluble material made of a molecular compound contained in the muscle tissue of humans and animals." The TROVAN ZIP QuillTMdissolves completely and is absorbed within three hours of insertion.

"This scientific breakthrough helps do away with unnecessary syringes and other implantation devices" stated Mr. Salomon. "It provides for unprecedented speed of application and eliminates medical waste. The TROVAN ZIP QuillTM comes individually packaged, presterilized in tear-off packages.

There is no transmission of infectious diseases, as can occur in reusable syringes, and no extensive personnel training is required. There are no transponder failures due to metal applicators or metal needles which can crack the glass capsule of the transponder as it is being extruded."

The TROVAN ID-100 transponder is one of the smallest animal implantable devices in the business, at only 11 - 11.5 mm length and 2.2 mm diameter.

It is made using a patented direct bonding technique which eliminates numerous structural components, thereby reducing the likelihood of component failure. The TROVAN ID-100 transponder has been endorsed by the Captive Breeding Specialist Group of the IUCN and by the Convention on International Trade of Endangered Species (CITES) based on its small size, great reliability and unmatched reading performance.

"Numerous trials and research projects have shown that the size of the transponder plays a major role in preventing transponder migration and breakage. The small transponder is not prone to migration within the muscle tissue, as are large transponders," said Mr. Salomon.

"In the future," said Dieter Salomon, "the TROVAN delivery device can also be used for delivery of pharmaceutical products, such as vaccines and antibiotica, in animals and humans. Trovan, Ltd. is actively seeking strategic partners and invites inquiries from interested parties regarding potential use of the TROVAN delivery device."

The TROVAN system is protected by eight patents with additional patents pending, and is marketed worldwide by Trovan, Ltd.

City of Los Angeles Selects InfoPet Identification Systems and Trovan® Technology for Identifying Pets in City Shelters

July 12, 1996

The Los Angeles Animal Regulation Commission voted unanimously July 8 to begin a microchip identification program with InfoPet Identification Systems, using the Trovan® microchip. The selection was made upon conclusion of an exhaustive evaluation of qualifying proposals submitted to the City.

In its "Evaluation of Microchip Proposals," the City of Los Angeles Department of Animal Regulation stated that "The Trovan® scanners offered by InfoPet were superior in all ways [...]. The Trovan® scanners detected the presence of microchips at a higher percentage [...and...] at a significantly greater distance [...]. The greater read distance of the Trovan® scanners is sufficient justification alone to award a contract to InfoPet."

Under the program the city will automatically implant the chips in all companion animals picked up as strays and adopted out. Animal Regulation director Gary Olsen is confident that the technology would be "a way of identifying animals more effectively." Olsen will also ask Mayor Richard Riordan to approve a charge of $15.00 for pet owners to bring in their pets for implanting.

The Animal Control Department estimates that up to 70% of the nearly 100,000 pets lost each year in Los Angeles currently have no form of identification. Los Angeles Animal Regulation Commissioner Camille Robins said she supports the measure as a way to reduce the high number of unclaimed strays that have to be put to death by the city, stating "I think it will save a lot of animals." Alexander L. Russell, InfoPet President and CEO, said "The InfoPet program will provide L.A. residents permanent identification for their pets while enabling the animal control department to save time and expense by quickly returning animals to their homes."

The Trovan® system offered by InfoPet has been endorsed by the A.S.P.C.A. and has been selected as the global standard for zoos and aquariums by the Captive Breeding Specialist Group of the I.U.C.N. Hundreds of zoos worldwide, as well as government agencies and municipalities in 21 countries are using the Trovan system for animal identification applications.

InfoPet Identification Systems is a division of TraceNET Technologies Inc., and a distributor for the Trovan® system for companion animals.
