We are looking to design a device for our locking system.
We like a Bluetooth or NFC receiving adaptor
That receives an assigned decimal number from a users phone app (a user ID)
Pushed from app bluetooth when in range of the bluetooth adaptor
The adaptor collects the user ID and pushes it via a rs232 comnection which this output then inputs to our locker terminal.
The output must be in decimal format.
The app must be able to be configured with a cloud based integration that will authenticate the user ID
