Description
This is a blank 13.56MHz RFID/NFC silicone bracelet. The tag contains a small RFID chip and an antenna and is passively powered by the reader/writer when placed a couple inches away.
These can be read by almost any 13.56MHz RFID/NFC reader but make sure it can handleISO/IEC 14443 Type A cards as there are a few other encoding standards (like FeLica) They are tested and work great with both ourPN532 NFC/RFID breakout boardandAdafruit NFC/RFID Shield for Arduino!
These chips can be written to& store up to 1 KB of data in writable EEPROM divided into banks and can handle over 100000 re-writes. You can use ourPN532 NFC/RFID breakout boardorAdafruit NFC/RFID Shield for Arduinoto read and write data to the EEPROM inside the tag. There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another -the ID number cannot be changed.
These use aISO/IEC 14443 Type A chipset which used to be the 'classic' NFC chipset. In ~2014 the NFC forum decided not to support this chipset anymoreso newer phones do not support it. This only matters if you're trying to use this tag with a phone/tablet.
