For communicating wirelessly between an electronic board and a smartphone.
By using NFC technology, it is possible to have a short-range wireless connectivity (10 cm) that allows for a two-way data exchange. It is therefore used in applications where data needs to be synchronized quickly and wirelessly between two devices.
A smartphone is normally used which reads and writes data via an app on the NFC module on the board.
Possible applications are the programming of an address and the transmission of some information obtained from the board (serial number, address, preset usage data).
