Three Tables" application launch of a low-voltage, low-cost, small size and non-contact card reader chip, smart instrumentation and portable handheld devices developed better choice. The digital part handles ISO14443A framing and error detection. In addition, support fast CRYPTO1 encryption algorithms, terminology validation products. It is between the host communication using SPI mode, helps to reduce connection, reduce PCB board size and cost. MFRC522 reader circuit chip design, easy to use, low cost, suitable for equipment development, development of advanced applications such reader users, This module can be loaded directly into a variety of readers molds. Module uses voltage of 3.3V, through the SPI interface simple few lines can be directly connected to the user any CPU board communication module can guarantee stable and reliable work, reader distance Package Included: 5 X RC522 module one 5 X Standard S50 Blank Card 5 X S50 shaped cards one (as shown keychain shape) 1 X Straight row pin 1X Curved row pin
