Abstract
A self-check apparatus is provided for processing a sales transaction of an article having an attached surveillance tag, each attached surveillance tag bearing a coded indicia such as a bar code. The self-checkout apparatus stores an indication of the articles which have been selected for purchase. When the surveillance tag is presented to the apparatus for deactivation, the bar code on the tag is scanned, and a check is made to verify that the surveillance tag is attached to an article which has been selected for purchase, and provided such verification is made, the surveillance tag is deactivated.
