6. Operating mode
The NFC 5V RS232 board operate with both user keys based on Mifare protocol (TGS Mifare and MyWellness
key) and NFC smartphones. The minimum reading distance with NFC devices must be at least 15 mm.
In the case of interaction with user key based on Mifare protocol, the board traces its operating states, based on
the use of fitness equipment by the athlete (eg, running a year) and through some parameters collected from
the user keys.
When the board reads a smartphone NFC, the data exchange between them is minimized, thanks to a NFC
application, installed in the smartphone (installed as prerequisite), which supports most of the data
management.
