Abstract
An electronic identification tag is made up of at least one cover strip and a carrier strip having an antenna and transponder mounted thereon, and an adhesive to secure the strips together such that the antenna is interposed between the strips, the transponder being pre-programmed to generate a signal having a unique code correlated with indicia on the tag to identify a passenger or luggage. The tag further lends itself well to a novel method of tracking luggage and passengers in a transportation facility.
