INVENTO IC Card RC522 RFID for Arduino M5 MFRC 522 Radiofrequency Inducing Reader Sensor Electronic Components Electronic Hobby Kit

MF RC522 is applied to the 13.56 MHz non-contact card chip, communication of high integration, speaking, reading and writing is the NXP company in view of the "three tables" application of a low voltage, low cost, small volume, non-contact card chip, in reading and writing is the intelligent instrument and a portable handheld device research and development a good choice. MF RC522 takes advantage of advanced concept of modulation and demodulation, fully integrates all types of passive under 13.56 MHz contactless communication mode and protocol. Support 14443 a compatible transponder signal. Digital part processing ISO14443A frame and error detection. In addition, it supports rapid CRYPTO1 encryption algorithms, expressions validation, MIFARE series products. MFRC522 support MIFARE contactless communication series more high-speed, bidirectional data transfer rate is as high as 424 kbit/s. As the 13.56 MHz card series chips, high integration, speaking, reading and writing the new members of the family, MF RC522 with MF RC500 and MF RC530 has many similarities, it also has many characteristics and differences. It with the communication between the host USES the SPI mode, is beneficial to reduce the attachment, could reduce the size of our PCB, reduce the cost.
