    摘要： A statistical basis for use in a self-scanning checkout system determines how many items to check in a shopper's shopping cart for incorrect or missing scans as well as which particular or types of items to check to determine if they were properly scanned, if the shopper is determined to be audited. The present invention does not audit every customer, but rather determines whether a given shopper or customer is to be audited on a given shopping trip based upon obtaining a minimum checkout loss for such customer. The methodology determines how many items to check for a given shopper as well as which particular items to check for that shopper. The following factors attempt to model the real world of shopping and may be considered, alone or in varying combinations, in determining the number of items to check for a particular shopping transaction: shopper frequency; queue length; prior audit history; store location; time of day, day of week, date of year; number of times items are returned to shelf during shopping; dwell time between scans; customer loyalty; store shopping activity and other factors. Using statistical decision theory for auditing policies a minimum loss per shopper transaction improves the security and reduces the labor of self-check out without being too intrusive to customers.

    摘要： The present invention relates to a personal shopping system for combined use in both the home of a user and a shopping establishment. The system includes a host computer which is coupled to a host modem and, optionally, to at least one wireless multi-access point. At least one shopping establishment kiosk cradle is employed to interface with a portable terminal which is also part of the system. The portable terminal can be used in both the shopping establishment and the home of the user. It is configured to read bar codes associated with items related to shopping, and includes a memory, a bar code reader, a wireless transceiver, and a data interface. The data interface of the terminal communicates with a data interface of the shopping establishment kiosk cradle. A home cradle for the portable terminal is also provided and is adapted to remain in the home of the user. It includes a home portable terminal-receiving station and a home data interface to communicate with the data interface of the portable terminal. A home data transfer circuit is also included to permit data exchange between the home data interface and the modem coupled to the host computer. The portable terminal can be provided with unique identifying indicia so that the terminal can serve as a form of identification for a user of the system. Database management of shopping lists for multiple establishments, including customer preferences, can be performed.
