RFID Reader/Writer RC522 SPI S50 with 13.56MHz RFID Card and Tag

Description
The RC522 is a RF Module that consists of a RFID reader, RFID card and a key chain. The module operates 13.56MHz which is industrial (ISM) band and hence can be used without any license problem. The module operates at 3.3V typically and hence commonly used in 3.3V designs. It is normally used in application where certain person/object has to be identified with a unique ID.

The keychain has 1kB memory in it which can be used to stored unique data. The RC522 reader module can both read and write data into these memory elements. The reader can read data only form passive tags that operate on 13.56MHz.

Features:

14443A compatible transponder signals.
Suitable for Smart meters and portable handheld devices.
Supports rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products.
Low cost, and ideal for user equipment development.
13.56MHz contactless communication card chip.
The low-voltage, low-cost, small size of the non-contact card chip to read and write.
Integrated MF RC522
ISO14443A frames and error detection.
MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s.
Can be directly loaded into the various reader molds, very convenient.
