Abstract

Devices (302, 702, 800) with embedded control programs are provided are provided with RF-ID devices (114, 504) or other non-contact read data carriers (604) that provide configuration data, on which the execution of the embedded control programs is contingent. Preferred embodiments include wireless communication devices (302, 702, 800) provided with RF-ID devices (114, 504) or set of magnets (604) that encodes data embedded in front fascia. Embodiments of the invention increase the security of configuration data, and allow for functionality to enhanced by replacing the front fascia.

Claims
