Radio frequency baggage tags

摘要: A radio frequency identification transponder tag (20) is built on a thin flexible substrate (30) and attached to an airline baggage label (10). The RF electrically programmable, physically self-adhesive compatible with existing labelling systems allow extra features be added such systems. interrogated by remote interrogation device includes plurality of antenna turns (32) formed circuit chip (54) having double metal layer contact pads (58,60,70,72) at intermediate portion thereof bonded (34,36) within the innermost turn (38) means conductive adhesive (80) that contained confined between areas structural (86) also interconnect (30).
