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.
