RC522 chip
MF RC522 is applied to the highly integrated read and write 13.56MHz contactless communication card chip, NXP launched by the company for the "table" application of a low-voltage, low-cost, small size of non-contact card chip, smart metres and portable handheld devices developed better choice.The MF RC522 use of advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols.In addition, support rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products.MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s.As new members of the 13.56MHz reader card series of highly integrated chip family, MF RC522 MF RC500 MF RC530 There are a lot of similarities, but also have many of the characteristics and differences.Communication between it and the host SPI mode helps to reduce the connexion narrow PCB board volume, reduce costs.
RFID module
The original Philips MFRC522 chip design circuit card reader, easy to use, low cost, and applies to the user equipment development, the reader and the development of advanced applications, the need for the user RF card terminal design/production.This module can be directly loaded into the various reader moulds.Utilises a voltage of 3.3V, through the SPI interface simple few lines directly with any user CPU motherboard connected communication can ensure that the module is stable and reliable work, distance card reader
