This is a blank 13.56MHz RFID/NFC card. It's commonly used for train and bus passes and other proximity - based systems. The card has a small RFID chip and an antenna. It gets power passively from the reader/writer when placed a few inches away. Almost all 13.56MHz RFID/NFC readers can read it, but ensure the reader supports ISO/IEC 14443 Type A cards as there are other encoding standards like FeLica. These cards are tested and work well with our PN532 NFC/RFID breakout board and Adafruit NFC/RFID Shield for Arduino. The chips can 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 mentioned boards to read and write data to the tag's EEPROM. There's also a permanent 4 - byte ID on the chip for tag identification. Note that this card uses a ISO/IEC 14443 Type A chipset. Since around 2014, the NFC forum stopped supporting it, so newer phones don't support it. This only matters if you plan to use the tag with a phone or tablet.
Using this 13.56MHz RFID/NFC card is easy. First, make sure your reader or writer supports ISO/IEC 14443 Type A cards. Place the card a couple of inches away from the reader/writer to power it passively. To read or write data, you can use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino. When writing data, remember the card can store up to 1 KB in writable EEPROM and handle over 100,000 re - writes. As for the permanent 4 - byte ID on the chip, you can use it to tell one card from another. Be aware that newer phones and tablets may not support this card because the NFC forum stopped supporting its ISO/IEC 14443 Type A chipset in around 2014. To maintain the card, keep it away from strong magnetic fields and physical damage. Avoid bending or scratching it, which could affect the chip and antenna.
