METHOD OF DISABLING AND ENABLING RADIO FREQUENCY IDENTIFICATION AFTER A PREDEFINED TIME PERIOD OR EVENT
First Claim
1. A computer implemented method for controlling a transmission state of a radio frequency identification transponder, the computer implemented method comprising:
- changing a value in an event indicator upon occurrence of an event;
comparing the value in the event indicator to a predetermined value; and
responsive to the value in the event indicator equaling the predetermined value, selectively changing a transmission state of the radio frequency identification transponder between a first state and a second state, wherein the first state activates a radio frequency identification signal transmitted by the radio frequency identification transponder, and wherein the second state deactivates the radio frequency identification signal transmitted by the radio frequency identification transponder.

Abstract
A method and system for controlling the transmission state of a radio frequency identification transponder. A value in an event indicator is changed upon occurrence of an event. The value in the event indicator is compared to a predetermined value. Responsive to the value in the event indicator equaling the predetermined value, the transmission state of the radio frequency identification transponder is selectively changed between a first state and a second state, wherein the first state activates the radio frequency identification signal transmitted by the radio frequency identification transponder, and wherein the second state deactivates the radio frequency identification signal transmitted by the radio frequency identification transponder.

20. A system for controlling a transmission state of a radio frequency identification transponder, the system comprising:
-
a transponder affixed to a product for sale, wherein the transponder transmits a radio frequency identification signal, and wherein the transponder comprises; a switching device, wherein the switching device opens a gate in a conductive path to disable the radio frequency identification signal and closes the gate to re-enable the radio frequency identification signal; a point of sale device for receiving the radio frequency identification signal; and a counting device comprising a count value, wherein the count value of the counting device is changed upon receipt of the radio frequency identification signal by the point of sale device; wherein the transponder disables the radio frequency identification signal when the changed count value of the counting device equals a predetermined value.

21. A computer program product for controlling a transmission state of a radio frequency identification transponder, the computer program product comprising:
a computer usable medium having computer usable program code tangibly embodied thereon, the computer usable program code comprising; computer usable program code for changing a value in an event indicator upon occurrence of an event; computer usable program code for comparing the value in the event indicator to a predetermined value; and computer usable program code for selectively changing, in response to the value in the event indicator equaling the predetermined value, a transmission state of the radio frequency identification transponder between a first state and a second state, wherein the first state activates a radio frequency identification signal transmitted by the radio frequency identification transponder, and wherein the second state deactivates the radio frequency identification signal transmitted by the radio frequency identification transponder.
