Abstract
In certain embodiments of surface material enhancement with radio frequency identification (RFID) tags, one or more RFID pressure assemblies are incorporated into a surface material. An RFID pressure assembly includes a pressure switch and an RFID tag. The RFID tag can be in an inactive state or in an active state. The RFID tag is generally in the inactive state, but the RFID tag is placed in the active state if a person applies pressure to the pressure switch. If the RFID tag is in the inactive state, the RFID tag fails to respond to an interrogation signal transmitted from an RFID reader. If the RFID tag is in the active state, the RFID tag responds to an interrogation signal by reflecting back a responsive signal. The responsive signal sent from the RFID tag may include a positional indicator of the RFID pressure assembly or an appliance control command.
