Abstract
A radio frequency identification (RFID) checkout system includes a reader, a first RFID tag, and a second RFID tag. The first tag is configured to be attached to an item selected to not be read by the reader, and the second tag is configured to be attached to an item selected to be read by the reader. Upon items being positioned within the reader, the reader reads the tags to determine if the first tag is present within the reader. The reader is enabled to complete a checkout transaction if no first tags are detected within the reader during the reading. The first tag includes an attachment base, an extension portion connected to the attachment base, and a RFID antenna connected to the extension portion. The extension portion is movable relative to the attachment base between at least a first position and a second position, and the extension portion extends away from the attachment base in the first position.
