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. ## Claims ### Claim 1 A method of verifying items selected for purchase at a checkout station comprising: receiving wireless tag data from wireless tags on the items at the checkout station using a wireless tag reader; adding the wireless tag data from the wireless tags to a list; receiving barcode data from barcodes on a number of the items at the checkout station using a barcode reader; adding the barcode data from the barcodes to a transaction record; comparing the wireless tag data from the list to the barcode data in the transaction record; and issuing an alert when the transaction record fails to include barcode data of one of the items when the wireless tag data of the one item is in the list. ### Claim 2 (depends on 1) The method of claim 1, wherein issuing an alert comprises displaying an indication to scan the one item, and issuing the alert after a predetermined time period when the barcode data of the one item is not received. ### Claim 3 (depends on 1) The method of claim 1, wherein issuing an alert comprises issuing the alert after a selection finalizing a total amount of the number of items is received. ### Claim 4 (depends on 1) The method of claim 1, wherein issuing an alert comprises issuing the alert after a selection to provide payment is received. ### Claim 5 (depends on 1) The method of claim 1, wherein adding wireless tag data comprises comparing read wireless tag data to wireless tag data in the list and only adding the read wireless tag data to the list when the read wireless tag data is not already in the list. ### Claim 6 (depends on 1) The method of claim 1, wherein comparing comprises removing one of the items from the list after the one item is scanned. ### Claim 7 (depends on 1) The method of claim 1, wherein adding wireless tag data comprises adding wireless tag data for each of a plurality of like items to the list. ### Claim 8 (depends on 1) The method of claim 1, wherein comparing comprises removing one of the like items from the list for each one of the like items that is scanned. ### Claim 9 An item security system at a checkout station comprising: a display at the checkout station; a wireless tag reader at the checkout station, including a plurality of antennas placed on the checkout station, wherein the plurality of antennas creates a reading boundary around the checkout station; a barcode reader at the checkout station; and a transaction terminal at the checkout station configured to: receive wireless tag data from wireless tags on the items at the checkout station from a wireless tag reader; add the wireless tag data from the wireless tags to a list; receive barcode data from barcodes on a number of the items at the checkout station from a barcode reader; add the barcode data from the barcodes to a transaction record; compare the wireless tag data from the list to the barcode data in the transaction record; and issue an alert when the transaction record fails to include barcode data of one of the items when the wireless tag data of the one item is in the list.
