7941 Reader Module 13.56MHZ

Its small size allows it to be widely applied in more devices, such as fingerprint machine, attendance machine, entrance guard. It also supports Frequency 13.56MHz cards.

A radio frequency identification reader (RFID reader) is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to transfer data from the tag to a reader. RFID systems can be classified by the type of tag and reader. PRAT, ARPT, ARAT. The RFID Reader can be used for low-cost projects such as office/home security, personal identification, access control, interactive toy, and production control systems, etc. The module sends data via the UART protocol, making the interface relatively easy.
