4. A distributed method of tag identification for identifying a missing tag comprising the steps of:
-
forming a group comprising a plurality of tags, each tag in the group being identifiable by an associated tag identifier; configuring at least one tag in the group to store at least one link to at least another tag in the group, whereby each tag in said group is linked to at least one other tag in the group; reading each of the tags in the group; storing, in a first set, the tag identifiers read in the reading step; storing, in a second set, the links that are read in the reading step; performing a comparison between the first set and the second set; signaling a missing tag if a mismatch is reported between the first set and the second set when the comparison step is performed. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
