Patent ID: 8766780

Claim:
A system comprising: a tag comprising: a tag processor; a radio frequency transmitter coupled to the tag processor; and a capacitively driven communication circuitry coupled to the tag processor, the tag processor to energize the capacitively driven communication circuitry to receive a serial set of binary bits via the capacitively driven communication circuitry; a host computer coupled to a radio frequency reader, the tag processor to direct the radio frequency transmitter to transmit a signal to be received by the radio frequency reader; and a controller comprising: a controller processor; a drive circuitry communicatively coupled to the controller processor; first and second voltage pads coupled to the drive circuitry, the controller processor to control the drive circuitry to manipulate charge on the first and second voltage pads in a pattern characteristic of a serial set of binary bits; and a radio frequency receiver, the controller to initiate a low information signal to be sent from a tag to be received by the radio frequency receiver, the low information signal not recognizable by the radio frequency reader.
