13.56MHz RFID/NFC Card - Classic 1K

This 13.56MHz RFID/NFC Card is a blank, rewritable proximity card with 1KB of EEPROM storage and a unique 4-byte ID, compatible with ISO/IEC 14443 Type A readers such as the PN532.

This is a blank 13.56MHz RFID/NFC card - often used for train/bus passes but also found in other systems where a proximity card is desired. 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 handle ISO/IEC 14443 Type A cards as there are a few other encoding standards (like FeLica) They are tested and work great with both the PN532 NFC/RFID breakout board and Adafruit 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 100,000 re-writes. You can use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino to 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 a ISO/IEC 14443 Type A chipset, which used to be the 'classic' NFC chipset. In ~2014, the NFC forum decided not to support this chipset anymore, so newer phones do not support it. This only matters if you're trying to use this tag with a phone/tablet. Features
