ABSTRACT:
A computer implemented method, apparatus, and computer usable program code for determining whether a set of items is complete. An interrogate signal is transmitted from a tag reader into an interrogation zone. Each item returning a response signal to the tag reader in response to the interrogate signal is included in a checked item set. The checked item set is compared to a set data. The set data identifies all items in a set of items, the set data is included in at least one tag associated with at least one item in the set of items, and the set data is included in at least one response signal received at the tag reader. A determination is made whether the set of items is complete, wherein the set of items is complete if every item identified in the set data is included in the checked item set.
