Portable scanning system including a surveillance tag deactivator.

摘要

A method and apparatus for reading bar code symbols and for electronically monitoring articles including a surveillance tag having an activated and a deactivated state including a scanner, a sensor having a field of view and operative for detecting at least a portion of light of variable intensity reflected off the symbol and for generating an electrical signal indicative of the detected light intensity. The apparatus further includes a processor to determine whether the reflected light of variable intensity is indicative of the presence of a predetermined indicia pattern such as a bar code symbol; and a deactivating module for transmitting a deactivating signal to said tag so as to change the state of the tag from an activated to a deactivated state.
