Patent ID: 8120463

Claim:
A method for improving the reliability of communication in an RFID system, said method comprising the steps of: computing on a first device a first interleaved parity code for a layer 3 transaction message; sending the layer 3 transaction message and the first interleaved parity code from the first device; receiving the layer 3 transaction message and interleaved parity code at a second device; computing on the second device, by a layer 2 of a layer protocol, a second interleaved parity code for the layer 3 transaction message comparing the first interleaved parity code and the second interleaved parity code by a layer 2 of a layer protocol; and based on the comparison, performing one of parsing and interpreting the layer 3 transaction message; detecting an error in the layer 3 transaction message and requesting a new message from the first device; and requesting a new message from the first device.
