ABSTRACT:
A process for laundering, sorting and delivering garments is enhanced by incorporating a Radio Frequency IDentification (RFID) tag into each garment. An RFID reader antenna includes left and right interleaved parallel and vertically aligned pluralities of generally orthogonal ferrite horseshoes to shape the sensing magnetic fields. The span of coverage along with the non-aligned magnetic fields ensure that RFID tag is read even regardless of orientation. Accurate detection facilitates tracking of garments during laundering, repair, replacement, sorting, etc.
