Description

RFID cards are most commonly seen controlling access to doors but they can also be used for things like inventory control or tracking objects. Using a reader like this could be used to build something like an escape room scenario that allows the user to progress only when an object is the correct orientation or placement. RFID tags could also be given to customers and used as a means to bill against their account. It differs from something like a QR code because it confirms the presence of the actual tag and can be used to trigger an action at a hardware level without the need for a smartphone or app.

The RFID module works by wirelessly powering the RFID tag IC and then communicating with it to verify its identity. This is done at a frequency of 13.56MHz.
