RFID Hardware

I am researching an RFID system for pet monitoring, and I am comparing hardware.
Looking at the tags that Parallax sells, they don't look too conducive to being on a dog or cat collar.
We had our dogs tagged with the RFID's, and I was wondering about the different techonologies used in the tags. Will the Parallax reader read only their own tags, or will it read all styles of RFID tags?

Thanks

Jason

    There are different tag styles, and I have some under-skin type tags that do work with our reader (got them from another forum member). You need to check with the vet to find out who manufactured the tags and their device type.

    Hi Jason...

    I researched this for an application that tracked police K-9s, and I tried·9 different dogs (in·5 different departments in·4 different states)·without finding a single one that the Parallax reader could read.

    As Jon said above, there are animal RFID "tags" that the Parallax reader can read, but these tags do not appear to be the ones that most vets/breeders are using - at least on the east coast, and in Texas.· In addition, I just imported an Alsatian puppy from Germany, and she came "chipped".· The Parallax reader will not read this one either.

    It's great hardware, but it doesn't seem to like the veterinary RFID tags.

    I found that our vet uses microchips from Avid. Is anyone familiar with the chips and how they work? I assume that a string (probably encrypted) is needed to activate the chip to send its information.
    I am not familiar with this, so I will be googling around.

    Jon, would you have that person with the sterile underskin tags contact me, please?

    I found the text below at http://www.avidmicrochip.com/answer.htm

    AccentQ.gifHow many brands of chips are there? Can shelters read the AVID® chip?

    AccentA.gifMicrochips operate by sending and receiving radiowave signals. Therefore they function at a particular frequency. In the United States the accepted and used radiowave frequency is 125 kHz. The chips most commonly used in the United States companion animal industry are AVID® and HomeAgain™. Shelters know and trust these microchip companies to provide fast recovery services for lost pets.

    In the mid 90's, shelter groups asked microchip companies to provide shelters with a "universal" scanner that could read both chips. Since then, rescue groups, shelters and humane societies can use a single scanner to detect any 125 kHz microchip.



    Is anyone familiar with methods of reading this type of microchip?

    Nope, I looked at the patents they hold and it is deliberately far reaching so its impossible to gauge what thier actual method adopted is.

    Here's that thread: http://forums.parallax.com/showthread.php?p=551161

    And the tags were not sterile.

    Thanks Paul and Jon.


    Bummer, now I am stuck. Does anyone have any ideas for tracking 3 cats in a common area?

    Ahh, I miss the ol' Bugs Bunny cartoons.

    For others reading, the Parallax system works on 170 kHz. There are many other frequencies in use including 125, 128, 130, and 134.5 kHz, 13.56, 433, 868 and 915mHz, 2.45, and 5.8 gHz. Don't hold me to those- I am close and there are probably more. I found that all are passive freq.'s except for 433 and 2450 mHz.

    How about building or finding a system using Atmel's U2270B one of the stated applications is animal identification, so it should work. If you decide to build one yourself, you should use the second or third application circuit. You can also find places that sell matched antennas so you dont have to bother designing one yourself.
