A device for a system includes a wireless transceiver, a memory, and a microcontroller. The microcontroller is communicatively coupled to the wireless transceiver and the memory. The microcontroller is configured to receive, via the wireless transceiver, user configuration data in response to a user approaching the system. The microcontroller is configured to store the user configuration data in the memory. The microcontroller is configured to transmit the user configuration data to an interface processor of the system to configure the system based on the user configuration data.
