Method and apparatus of obtaining security tag operation using local magnetic marker

Abstract

Disclosed is a method and an apparatus implying nearly 100% security with a tag system showing low cost and compact volume. Like a conventional tag, the disclosed tag system will respond properly to an interrogation signal. In addition, the disclosed tag system is able to monitor the environment local to a merchandise. Whenever the merchandise package is opened and/or impaired, alarm will be generated on the spot. It is almost impossible to disarm the tag system, unless a password is attained. The disclosed tag system shows a high sensitivity, and it does not need an electronic searching machine, or an interrogation gate, to operate. When combined with an electromagnetic transmitter, a smart tag system results, allowing merchandise to be traced on the computer screen, capable of performing discriminative tasks according to the imposed regulation rules on the merchandise IDs.
