MFRC-522 RC-522 mini RC522 Antenna RFID IC Wireless Module For Arduino IC KEY SPI Writer Reader IC Card Proximity Module

From the shop's description

The MF522-MINI module uses the RC522 original chip to design the card reader circuit. The module works at 13.56MHz frequency and conforms to the ISO14443A standard. It can support Mifare1 $50, Mifare1 $70, Mifare Light, Mifare UltraLight and Mifare Pro. Suitable for users of advanced applications such as device development and card reader development, and users who need to design/produce RF card terminals. This module can be directly loaded into various reader molds. The module adopts a voltage of 3.3V, and can directly connect with any CPU board of the user through several simple lines of the SPI interface, which can ensure stable and reliable operation of the module and long reading distance; the module is easy to use, highly reliable and small in size. Features such as helping customers to easily and quickly apply contactless cards to the system.. Featured By RoboticsBD.
