NEW PRODUCT – MiFare Classic (13.56MHz RFID/NFC) Bracelet [1KB]. This is a blank MiFare Classic silicone bracelet – often used for parties/events or identification but also found in other systems where a small proximity card is desired. The bracelet contains a NXP S50 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 MiFare cards as there are a few other encoding standards (like FeLica) They are tested and work greats with both our 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.

S50 chip specification:

  • 1 KiloByte (8 KiloBit) non-volatile EEPROM storage
  • Built in encryption engine with 48-bit key
  • 4 Byte unique identifier burned into the chip
  • 13.56 MHz frequency

Bracelet specification:

  • Fits wrists/ankles/hands up to 70mm (2.75″) diameter 25.4mm diameter
  • Bracelet made of rugged waterproof silicone
  • 0.9 grams / 0.03 oz
  • Works about 1″ away from reader
  • Weight: 14.86g

  1. I’m so happy to see you guys carrying more kinds of RFID tags!

  2. hey it’s like those magical power bracelets they sell at the mall,… except these actually do something lol

  3. And I thought you had entered the magnetic bracelet business.
