13.56MHz RFID/NFC Sticker [1KB]

This blank 13.56MHz RFID/NFC sticker is a versatile solution. It's commonly used for inventory management but can be applied wherever a sticker is needed. The sticker has a small RFID chip and an antenna. It gets power passively from the reader/writer when placed a couple of inches away. Most 13.56MHz RFID/NFC readers can read these stickers. However, ensure the reader supports ISO/IEC 14443 Type A cards as there are other encoding standards like FeLica. These stickers have been tested and work well with our PN532 NFC/RFID breakout board and Adafruit NFC/RFID Shield for Arduino. The chips can store up to 1KB of data in writable EEPROM divided into banks and can handle over 100,000 re - writes. You can use our PN532 breakout board or Adafruit shield to read and write data to the tag's EEPROM. Each chip has a permanent 4 - byte ID for tag identification, and this ID can't be changed. Note that these use an ISO/IEC 14443 Type A chipset. Since around 2014, the NFC forum stopped supporting this chipset, so newer phones may not support it, which only matters if you want to use the tag with a phone or tablet.

Using these 13.56MHz RFID/NFC stickers is easy. First, make sure your reader or writer supports ISO/IEC 14443 Type A cards. Place the sticker a couple of inches away from the reader/writer, and it will get powered up. You can then use our PN532 NFC/RFID breakout board or Adafruit NFC/RFID Shield for Arduino to read and write data to the sticker's EEPROM. Remember, there's a permanent 4 - byte ID on each sticker that can help you tell one sticker from another. When it comes to phones and tablets, keep in mind that newer ones may not support these stickers because the NFC forum stopped backing the ISO/IEC 14443 Type A chipset in around 2014. As for maintenance, just keep the stickers clean and dry. Avoid bending or scratching them too much as this could damage the chip and antenna inside. Also, don't expose them to extreme temperatures or strong magnetic fields, as these can affect the sticker's performance.
