Patent ID: 8665073

Claim:
A radio frequency identification (RFID) tag system, comprising: a storage module storing information comprising data; wherein the stored data comprises a full serialized identifier; wherein the full serialized identifier comprises: a first plurality of bits comprising a non-serialized portion of the identifier containing a product Stock Keeping Unit (SKU); a second plurality of bits comprising a trailing serialized portion of the identifier that provides a unique item-level ID; a logic module executing instructions to: receive a first signal from an RFID reader comprising a command to enter one of a plurality of modes of tag operation; wherein the modes comprise a first mode wherein the tag transmits the second plurality of bits in a response to a reader signal, and a second mode wherein the tag omits some or all of the trailing serialization portion of a transmission in response to said reader signal, and wherein the transmission does not include the second plurality of bits, wherein the command to enter the second mode comprises an indication of the number of bits in at least one of the first plurality of bits and the second plurality of bits; and said response comprises a calculated CRC that does not include the second plurality of bits.
