Abstract

Private paging already exists for hospitals and bar code scanners are widely used in many stores. Pen type scanners are also current technology. Calculators are a low cost and readily available feature which have already been installed as features to shopping carts. However, the combination of pager, bar code scanner, calculator along with an RF link for mass consumer use has yet to be developed.

PERSONALBARCODESCANNERAND CONSUMER PRICE REGISTER WITH CALCULATOR

  Private paging already exists for hospitals and bar code scanners are widely used in many stores. Pen type scanners are also current technology. Calculators are a low cost and readily available feature which have already been installed as features to shopping carts. However, the combination of pager, bar code scanner, calculator along with an RF link for mass consumer use has yet to be developed.

  This invention embodies such an idea. The system/ units would be usable by any store selling products with UPC type bar code labels. Consumers would be able to keep an accurate total of selected items prior to check- out using the merchandise bar code label. In some stores calculators have already been attached to shopping carts. The paging/calculator/bar code reader would be attached in a similar fashion. The consumer would be able to use the pen bar code reader to obtain price/product infor- mation and then make their decision purchase. This would be of great benefit to the consumer. The task of pricing items singularly or collectively could then be elimi- nated thus resulting in a cost reduction for stores.

  Business' utilizing this system would have a low power transmitter which would be used to convey the bar code and corresponding price/product information of all the items in the store. A drawing of the unit is shown in Figure 1. When a consumer found an item they were interested in they would then use the pen to scan the bar code. This code would be held in tempo- rary memory. After the code is read the unit would then begin price/product information acquisition. Three pos- sible methods can be utilized in obtaining the information.

METHOD 1

  The low power transmitter would continually out- put the latest bar code and corresponding price/product information of all the items in the store. When a bar code was scanned by the consumer the portable unit would correlate it against the received signal until it matched at which time it would then decode and dis-

play the price/product information. In this scenario the receiver would act as a paging receiver which scans for a single address (corresponding to the bar code) which when found decodes the product information. This method would be useful where the transmit bit rate was extremely high or the amount of products in a particu- lar store was fairly small. This method would not require the use of a database for storage purposes as in method
2. The use of a synthesized receiver would allow for the possibility of using the last digit scanned in the ba...
