NXP Semiconductors MFRC523

The MFRC523 is a highly integrated reader/writer for contactless communication at 13.56 MHz. The MFRC523 reader supports ISO/IEC 14443 A/MIFARE mode. The MFRC523’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry.
