13.56MHz RFID/NFC Card [1KB]

This blank 13.56 MHz RFID/NFC card contains a Mifare Classic 1K chip with 1 KB of writable EEPROM storage. The standard credit-card-sized form factor (ISO 7810 ID-1) makes it suitable for access control badges, identification systems, and RFID prototyping. 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.
