An apparatus for applying a programmable transponder to a target includes an applicator disposed adjacent to a tagging zone into which the target is conveyed and a feed-system for transporting a label to the applicator, each of the labels having a programmable transponder. A radiation source is disposed to illuminate a programming zone into which the label is transported. This radiation source communicates tag-information to the transponder. The communication of tag-information can occur either before or after the transponder is applied to the target.
