I managed to source some 13.56Mhz 12mm x 2mm NFC Glass capsules / tags from China and I’m happy to sell them for 10$ a piece. If you want one please contact me, I’m too lazy to list them on any online auction stores etc.
The read range is pretty much limited to contact when using them with a mobile phone reader or other low range reader device.
They are not sterilized so should not be used for human implants and they are based on the NXP semiconductors 15693 chip.
They are read/writable, not Mifare (See above).
The MoQ for is 500 and at that point the price drops to 5$ per unit.
Special offer during Feb/March 2013 — Order 20 tags for just 160$
