An electronic radio frequency (RF) identification system 10 is disclosed
and claimed. The system includes an interrogator 11 and a plurality of RF
transponders 12.1 to 12.n. In use, each transponder is operative
in response to an interrogation signal 14 to respond with a forward error
correctable data message 16.1 including base data encoded as symbol characters
in accordance with a forward error correcting code, such as a Reed Solomon Code,
and check characters on the base data as defined in the forward error correcting
code. The interrogator 11 utilizes data relating to the forward error correcting
code, the symbol characters and check characters in the received forward error
correctable data message, to reconstruct the base data in the event of corruption
of the forward error correctable data message during transmission.
