Hello Everyone,
I have several thousand 8mm glass tags made by Sokymat. These tags use the unique protocol which works fine with the Parallax Reader. These tags normally sell for about $2.50 each (depending on import duty taxes, they are made in Switerland). These are the same RFID tags inserted into dogs and cats for ID purposes.I'm offering these in lots of 10 for $15.00 (plus 3.00 S&H&I), 100 for $125.00 plus S&H&I. These are great for things like tracking RC vehicles on a stunt course, attaching to the bottom side of RC race cars for reading when passing through a finish line, and many other purposes. By the way, these are made by the same company that makes the reader chip on the Parallax RFID reader and they are all 125Khz. These work perfectly with the Parallax reader.

    It's Only A Stupid Question If You Have Not Googled It First!!

    Mr. Bailey,

    I am a school teacher at a small rural high school in Arkansas.· I am working on a system to take attendance and I have the software worked out using Qbasic that would print absentees based on a comparison of a list of students vs the list created by something like the RFID tags.· I would be interested in 100 or so of the tags if you still have some left.

    If you manage to inbed these in the students, let us know when the court date is. I'm sure we'll all be interested in the outcome - smile.gif

    More seriously, these are small "capsules" meant for inbedding into animals (or objects). By the time you mount these on something politically correct, you might be better off just buying the "cards" from Paralax or other sources. They are about credit card sized, and you can attach a "sticker" or label. In your case, you could possibly make an "ID Card".

    You may also find using an ID card with a bar code less expensive.

    These RFID tags also have a very short read distance, so you'd have to have the students "swipe" the card (or whatever you affix the capsule to) very close (within inche(s)) of the reader. These capsules and the RFID Reader from Parallax won't read as the tag passes through a door, unless the tag is passed very close to the reader.

    I suspect that even if you did use a different RFID technology that could read tags that were passing through the doorway (not requiring the students to "swipe" the card in some manner), you could end up with "invasion of privacy" issues. I'm not saying this is right, just saying that SOMEONE will be offended and be able to afford a laywer.

    Personally, I like the concept. I could also see stundents being required to wear a transmitting GPS to report their position to the school and/or truant officer. I also realize that I am not likely to be elected to public office.

    I might imbed them into the covers of their books.· Of course I realize that they will have to swipe them to be able to be counted present but I would like to experiment with this technology.· I would probably rather have the cards but if I can save a buck for each tag, I think I could make them work.

    Hello Everyone,
    Depending on the reader, the maximum distance you'll get for a read is about 4 inches. I've done things to extend their range in the past. You can wrap a small wire around them with a little pigtail and extend their ranges. I've also embedded them in wooden pens using conductive methods to attach the,m to the pen clip which also can extend their range. Low frequeency has three large markets. Automotive where they use it for Key FOBS gaining entry, agriculture, where they embed them in cattle and other livestock for identification, and building security for access control. All of these markets actually want short read distances for security. One last note. A coil antenna has a longer range than a circuit board antenna because you can "stack" the windings.
