ABSTRACT:
RFID systems, devices, software and methods are adapted for receiving from an RFID tag at least waves that communicate at least a first version of its code. An output tag code is output that is the same as the first version, if a fidelity criterion is met regarding the first version. If not met, the output tag code is instead a final version that is reconstructed from the first version, and also from any additionally optionally subsequently received versions. In some embodiments, an error recovery block includes a subcomponent fidelity criterion checking block that can determine whether the fidelity criterion is met, and a code reconstruction block that can derive the final version.
