Abstract:
1. A method for controlling a range of a radio frequency identification tag signal, the method comprising: identifying a desired operative range for the radio frequency identification tag signal of a radio frequency identification tag, wherein the radio frequency identification tag comprises a set of conductive paths, each path of the set of conductive paths comprises at least one resistor such that each of the set of conductive paths comprises a different one of a set of resistances; and selecting a set of conductive paths in the radio frequency identification tag corresponding to the desired operative range, wherein the set of conductive paths controls the range of the radio frequency identification tag signal in the radio frequency identification tag by altering the total resistance of the tag by directing current through the at least one resistor of different ones of set of conductive paths, wherein the step of selecting the conductive path comprises establishing an electrical connection between the first terminal and the second terminal by connecting the first terminal and the second terminal with at least one of a conductive ink marking and a graphite marking.
