Abstract

Disclosed is a system and method that provides an additional data source for the Self Check Out Security Scale System. Many existing SCO(Self Check Out) systems use a security scale to validate that the item scanned by the customer is the same item that was placed in the bag. Note: the bagging mechanism resides on a security scale. The SCO systems use the security scale to determine if the item that was placed on the scale falls into a range of acceptable limits that are calculated for the particular item. A problem exists in that the calculated limits for each item are determined by taking a large sample of weights of the same item as they are sold and eventually placed on the bagging platform of the security scale. Depending on the type of item and the amount of traffic of this item through the SCO lanes, it can be quite a long time until the actual weight limits and variances can be calculated.

Self Check Out System Security Scale Enhancement

   Disclosed is a system and method that provides an additional data source for the Self Check Out Security Scale System. Many existing SCO(Self Check Out) systems use a security scale to validate that the item scanned by the customer is the same item that was placed in the bag. Note: the bagging mechanism resides on a security scale. The SCO systems use the security scale to determine if the item that was placed on the scale falls into a range of acceptable limits that are calculated for the particular item. A problem exists in that the calculated limits for each item are determined by taking a large sample of weights of the same item as they are sold and eventually placed on the bagging platform of the security scale. Depending on the type of item and the amount of traffic of this item through the SCO lanes, it can be quite a long time until the actual weight limits and variances can be calculated.

Disclosed is a simple solution to this problem. The solution is to use the front end POS(Point Of Sale) attended work stations as an additional source of data to "seed" the sampling algorithm for the SCO security scale subsystem. All of the weight data for items from the front end POS attended work stations can be aggregated and sent to the SCO system security scale application. The additional source of data reduces the amount of time it takes for the security scale system to establish valid weight ranges for the items so...
