Technology is described for imaging device (e.g., x-ray detector) that includes a tag reader. In one example, the imaging device includes a imaging matrix of pixel detector elements, a wireless local area network (LAN) transceiver, a tag reader, and a controller. Each pixel detector element is configured to detect photon energy. The wireless LAN transceiver is configured to transmit imaging matrix data to at least one wireless access point (WAP). The tag reader is configured to read WAP configuration data from a close proximity tag. The controller is coupled to the imaging matrix, the wireless LAN transceiver, and the tag reader. The controller is configured to initialize the wireless LAN transceiver for communication with a specified WAP using the WAP configuration data. The at least one WAP includes the specified WAP.
