This is a glass, cylindrical RFID tag; it's very similar to those implanted into pets for identification purposes. But really guys, it's not for use inside your body.

Please don't implant this thing into yourselves.

Each tag comes with a unique 32-bit ID code and is not reprogrammable. The carrier frequency of this tag is 125kHz, so it works great with our ID-2, ID-12 and ID-20 RFID readers.
 

We tested this RFID tag with one of our ID-12 readers and measured a maximum read distance of about 10mm.
