A system and method for a door system is disclosed. The system produces an inductive power transfer signal and modulates the inductive power transfer signal. The system also encodes data within the modulated inductive power transfer signal and transmits the signal at a door frame of a door. At the door, the system receives the modulated inductive power transfer signal and extracts data from the received signal, and transduces the received signal into a door power signal. The system also supports secure data transfer by encrypting the encoded data at the door frame and decrypting the extracted data at the door. As a result, the modulated inductive power transfer signal between the door frame and the door provides a secure wireless data transfer channel for configuring components at the door and/or displaying data at the door, while also providing power to components at the door.
