Adafruit 13.56MHz RFID/NFC Bracelet - NTAG213 Chip

This blank 13.56MHz RFID/NFC Bracelet with an NTAG213 chip is versatile for various applications, including train passes, contactless payment, and information sharing. Its design incorporates a small RFID chip and antenna, functioning passively through near-field communication.

With compatibility across almost any 13.56MHz RFID/NFC reader that supports ISO/IEC 14443 Type A cards, this bracelet offers seamless integration into existing systems. Its secure NTAG chipset ensures widespread usability across smartphones, bypassing patent issues seen with MiFare cards.

The bracelet's writable EEPROM stores up to 144 bytes of data, divided into 4-byte banks, and accommodates over 10,000 rewrites. It also features a unique, permanent 7-byte serial ID for reliable differentiation. Use PN532 NFC/RFID breakout boards or Adafruit NFC/RFID Shield for Arduino to manage data efficiently.
