Abstract
An item security system and method of verifying items selected for purchase at a checkout station which focus on reducing losses at the checkout station as opposed to exits. One example method includes reading wireless tags on items at a checkout station by a wireless tag reader, reading barcodes on a number of the items at the checkout station by a barcode reader, comparing the number of items with read barcodes to the items with read wireless tags, and issuing an alert when the number of items is less than all of the items.
