Abstract: System and methods for optimizing communications between an RFID reader and a population of tags are described. To minimize the amount of data exchanges, the reader and tags use non-sequential bit string or byte masking. In non-sequential bit string masking, the reader transmits an interrogation mask having a plurality of non-sequential sub-masks to the tags. During subsequent collection of the identification sequence, the reader and tags only exchange the non-masked bit positions. The interrogation mask can be determined using superposition processing, historical tendencies, or known identification and/or subset of identification ranges. During superposition processing, the reader determines whether a bit position contains a single value or multiple values for tags in the tag population. If the bit position contains a single value, the bit position is designated as masked. If the bit position contains multiple values, the bit position is designated as non-masked.

In an alternative embodiment, the invention operates by obtaining data from a memory of a RFID tag, wherein the memory has a first partition and a second partition, generating a new ID, and writing the new ID to either of the first partition or the second partition of the RFID tag. If such write is verified, then the new ID is written to the other partition of the RFID tag. The data from the tag is used to lookup a subject's record in a database.

Abstract: Memory contents in an electronic key are re-programmed using a base station from a multi-byte pre-existing or default value. If writing the new secret code value is interrupted and results in a partially-written value then a first recovery code is formed comprising a leading portion having values matching a corresponding portion of the pre-existing secret code and a trailing portion having values matching a corresponding portion of the new secret code. The first recovery code is transmitted to the electronic key for comparison with the stored secret code value. The electronic key compares a received secret code value in response to the first recovery code with the stored secret code value. If the comparison detects a non-match, then interaction with the base station is suspended. If the comparison detects a match, then interaction with the base station is continued in order to accept the new secret code value after re-transmission in full from the base station.

Abstract: An RFID tag has an antenna to receive a configuration signal, and a circuit with a controller that can configure the RFID circuit responsive to the configuration signal. Configuring is such that the tag backscatters by impressing data either on the carrier frequency, or on a subcarrier in addition to the carrier signal, depending on the configuration signal. In the event of a subcarrier, the tag controller may optionally further determine a frequency of the subcarrier from the configuration signal.

The reader has an interface to receive an input indicative of a present geography, and a lookup table for determining an operating parameter based on the present geography. In one embodiment, the operating parameter is determined from regulations at that geographic location.
