Abstract
Provided among other things is a tagging system for identifying closely proximate stacked items (e.g., thin and flat closely spaced items) each of which is tagged with an electronic radiation emitting chip with a built-in antenna incorporated therein. The tagging system comprises: (1) the tagged, closely spaced items, wherein the electronic radiation emitting chips are affixed on, and within the width of, thin side edges of the items; and (2) an ID reader capable of reading the IDs (identifiers) stored electronically on the chips, wherein the electronic radiation emitting chips are sufficiently aligned on the items such that the chips can be serially read with the ID reader.
