Security tag deactivation system

摘要

A method for tracking deactivation of security devices being associated with items to be sold, each of the items being associated with a tracking identifier. The method includes determining a number of security tag deactivations which should occur using select ones of the identifiers and determining a number of actual security tag deactivations which occurred. The method then compares the number of actual security tag deactivations to the number of security tag deactivations which should have occurred, and generates an output when the comparing results in an inconsistency therebetween.
