Abstract: A system for acquiring shopping list information includes a user terminal and a base unit in selective data communication via a wide-area network, such as the global Internet, common data carrier or a modulated wave propagating over a public utility. The user terminal includes a bar code scanner for getting Uniform Product Code information from a product container or from a manufacturer's coupon. The user compiles, via the user terminal, a shopping list database by scanning previously obtained products, manufacturers coupons, or using direct user input via an interface such as a keyboard or mouse. Once compiled, the database is selectively transmitted to a base unit situated at a retailer via the wide-area network.

Abstract: A hand-held data entry device having both portable and fixed point-of-sale modes. The device includes a housing having a chassis for carrying a bar code scanner and a microprocessor-based system that stores inventory data relating to goods, and further having a removable and reversible panel for permitting a display and keyboard to be remounted in an upside-down orientation relative to the direction of scanning. In this manner, a pistol-grip handle used by the operator in the portable mode may be also used as a mount for the device in the fixed point-of-sale mode. In the fixed point of sale mode, the device is mounted thereby to a transaction device, such as a cash register, such that the scanner's beam of light is directed approximately vertically downward to scan the universal product code of goods that are passed below the scanner.
