13.56MHz RFID/NFC Leather Keychain Fob [1KB]

This blank 13.56 MHz RFID/NFC keychain fob features a leather housing with a key ring attachment, giving it a more polished look than standard plastic fobs. It contains a Mifare Classic 1K chip with 1 KB of writable EEPROM storage. The embedded chip and antenna are passively powered — no battery is needed.

The chip stores data in writable EEPROM divided into banks and supports over 100,000 re-write cycles. A permanent 4-byte serial number is factory-burned into each chip for unique identification.
