Abstract

A method and system for controlling distant equipment. A passive radio frequency identification (RFID) tag within a Programmable Secure Remote Controller (PSRC) receives a radio frequency (RF) signal from a transmitter integrated in the distant equipment. The distant equipment is external to and remote from the PSRC. The PRSC does not include an internal source of energy and requires energy from an external source to operate. The PSRC is configured to distribute sufficient energy from the RF signal to components of the PSRC to enable the components to operate. The RFID tag is activated to generate information and the information is decoded to identify the distant equipment. A request to perform an operation that controls the distant equipment is received. After the request is received, a first predefined scenario is activated for performing the operation that controls the distant equipment.
