RF identification tag for communicating condition information associated with an item
First Claim
1. A radio-frequency (RF) identification tag configured to transmit at least one dynamic electronic product code (EPC) associated with at least one item, the at least one dynamic EPC configured to include at least one portion that is variable based at least in part on at least one detectable condition associated with the at least one item.

Abstract
An embodiment of the invention is directed to a radio-frequency (RF) identification tag configured to transmit at least one dynamic electronic product code (EPC) associated with at least one item, the at least one dynamic EPC configured to include at least one portion that is variable based at least in part on at least one detectable condition associated with the at least one item.

28. A radio frequency identification tag, comprising:
-
at least one storage device storing at least one dynamic identifier associated with at least one item, the at least one dynamic identifier configured to include at least one variable portion that has at least one of a variable content and a variable length based at least in part on at least one detectable condition associated with the at least one item, wherein the at least one dynamic identifier includes at least one dynamic electronic product code (EPC);
the at least one storage device is configured to be updated periodically so as to refresh the at least one dynamic EPC based on at least one change in the at least one detectable condition associated with the at least one item;
the at least one detectable condition includes at least one temperature associated with the at least one item;
the at least one variable portion of the at least one dynamic EPC includes at least one representation of the at least one temperature;
the at least one dynamic EPC further includes a fixed portion including at least one of;
a first identifier related to a source of the at least one item;
a second identifier related to a product type of the at least one item; and
a third identifier related to a serial number of the at least one item;
the at least one storage device is configured to store the at least one dynamic EPC as a variable binary number; and
the variable binary number includes at least 64 bits.
