The module communicates over UART or I2C with simple protocols. It also has 2 general purpose inputs and 2 general purpose outputs for switches, relays, etc.
Check below for Mifare RFID tags.
Note: You will need an antenna or evaluation board for this module to work. Check the related product below.
RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to identify objects in a contactless way; itÂ is also called proximity identification.
There are 2 elements in RFID communications: the RFID module (or reader/writer device)Â and an RFID card (or tag). The RFID module acts as the master and the card acts as the slave; this means the module queries theÂ card and sends instructions to it. In a normal RFID communication, the RFID module is fixed and the user takes his card near itÂ when he needs to start the interaction.
