I know this subject has been raised before, but the Firmware has moved ahead since then and interaction with speeduino is more mature now. The question is, would it be better to implement this in the GPIO board or on the main Controller.
The issue was also Bluetooth or RFID.
Has any one experimented with it?
I'm thinking of RFID because that does not need a charged cellphone and idle power drain is lower.
