Adafruit 13.56MHz RFID/NFC Clear Tag - Classic 1K

This blank 13.56MHz Classic 'laundry' tag is a versatile tool primarily for laundry and identification systems. Its transparent design houses a tiny RFID chip and antenna, passively powered by proximity to a reader.

Compatible with nearly any 13.56MHz RFID/NFC reader supporting ISO/IEC 14443 Type A standards, these tags seamlessly integrate with existing systems. Benefitting from robust compatibility, they perform excellently with the PN532 NFC/RFID breakout board and Adafruit NFC/RFID Shield for Arduino.

With writable EEPROM storing up to 1 KB, it handles over 100,000 re-writes, efficiently supporting dynamic data storage. A permanent 4-byte ID provides unique tag identification and security, distinguishing each tag swiftly.

Though newer phones may not support this classic NFC chipset since the NFC forum's decision in 2014, it stands unrivaled in specialized applications demanding compact, durable proximity cards.
