Abstract: A system for verifying deactivation of an EAS tag at a self-checkout counter includes an electronic article surveillance (EAS) tag deactivator for deactivating EAS tags attached to articles processed at a checkout station and an EAS tag interrogator associated with the checkout station that generates an electronic checkout disable signal in response to detection of an EAS tag by the EAS tag interrogator. The checkout disable signal may be used to disable the operation of a self-checkout station component so that the consumer is unable to process additional articles until the EAS tag deactivation operation is successful. The generation and use of the checkout disable signal helps ensure that a consumer at a self-checkout station deactivates all EAS tags attached to articles processed at a self-checkout station during checkout. The checkout disable signal may be sent to the processor of the terminal of the self-checkout station to cause the processor to disable components of the self-checkout station.

Abstract: Techniques for arrangement of components in a bar code scanner so as to make efficient use of space are described. A scanner includes a single scan window, a laser source for producing a laser beam, a rotating optical spinner to reflect the laser beam to produce a scan beam and a collection of fixed mirrors to reflect the scan beam in order to give it a desired optical length and to direct it out of the scan window. In order to make efficient use of space within the scanner, the spinner comprises a multifaceted hollow reflector, and a collector mirror is placed within a volume bounded by the reflector. The space made available by placement of the collector within the volume bounded by the collector makes it possible to arrange the collection of fixed mirrors such that the scan beam experiences at least three reflections after leaving the spinner.

Abstract: A system for creating, storing and retrieving secure transaction receipts. These transaction receipts may be stored on portable electronic media that can be carried by a consumer. Each transaction record contains information detailing the product or service purchased as well as a merchant ID and a customer (or other user) ID and an encrypted signature created from that data. The data can be further protected by the use of an optional user password. Examples of suitable portable storage media are personal computer diskettes, magnetic stripe cards or smart cards. The secure electronic transaction receipts may be used as substitutes for paper receipts. The portable electronic media is capable of storing a large plurality of such transaction records, thus simplifying a number of record keeping procedures, such as expense reporting and data entry for personal finance programs.

The system includes an RF interrogator which transmits signals at a plurality of different frequencies and which receives first frequencies of the plurality of different frequencies from an item label, and a computer which determines second frequencies of the plurality of different frequencies which were not received by the RF interrogator, and which determines an item identification number from the first and second frequencies by assigning first values equal to a first binary value to first data bits occupying first data bit positions in the item identification number for the first frequencies and assigning second values equal to a second binary value to second data bits occupying second data bit positions in the item identification number for the second frequencies.

Abstract: Techniques for cost effectively displaying a bagging indicator by an electronic price label (EPL) are described. An EPL computer reads an EPL data file to determine if an item contains a bagging indicator. The EPL computer transmits a message to an EPL associated with the item which includes a command for the EPL to display a bagging indicator. The EPL then displays the bagging indicator, providing valuable information to customers who are in the process of making purchasing decisions. In one aspect, one or more colored areas on a face plate of the EPL are formed by silkscreening. An EPL liquid crystal segment shaped substantially similar to the colored area is aligned behind each of the colored areas. When the EPL segment behind a colored area is not active, the color is visible to customers, providing the bagging indicator.
