Abstract: Reliable communication is provided by a radio frequency identification system comprising at least one of an interrogator (102) and a transponder (104). The interrogator (102) transmits a plurality of interrogator frames (106) and receives at least one of a plurality of transponder frames (114). The transponder (104) transmits the plurality of transponder frames (114) and receives at least one of the plurality of interrogator frames ( 106). Each frame in the plurality of interrogator frames and the plurality of transponder frames includes an initialization sequence (108 and 116), at least one information sequence of a first predetermined length (110 and 118), and a check sequence of a second predetermined length (112 and 120) for each information sequence.

Abstract: A portable data device employs an integrated circuit having a signal processor that receives a power signal from an external source via a power node. A decoupling device is placed between the power node and the signal processor. An energy reservoir is placed in parallel with the signal processor, which acts in concert with the decoupling device to isolate the effects of the signal processor from the rest of the integrated circuit.
