This card reader module based on the NXP MFRC522 or Fudan Semiconductor FM17522 chip design circuit, is easy to use and low cost. This module can be directly loaded into the various reader molds. Utilizes a voltage of 3.3V. Through the SPI interface it can be connected directly using few lines with any user CPU motherboard.

NXP MFRC522/FM17522 is a highly integrated contactless reader operating at 13.56MHz chip next support in line with ISO / IEC 14443 non-contact reader mode Type A protocol. While providing a low-power external card detection function to facilitate battery-powered, requiring low-power operation and require real-time processing of any time will enter the RF field external card reader device. NXP MFRC522/FM17522 a low voltage, low power consumption, driving ability, multi-interface support and other features. For low-power, low-voltage, low-cost requirements of the non-contact reader applications.
