Abstract
A point of sale terminal that performs purchase transactions is presented. The point of sale terminal includes an optical code scanner and weigh scale device. The optical code scanner portion of the optical code scanner and weigh scale device continuously scans for an optical code while the weigh scale portion of the optical code scanner and weigh scale device weighs an item placed on the scale. When the point of sale terminal receives data for an optical code that is read during the time an item is being weighed, the point of sale terminal compares information from the optical code data to the identification data entered by an operator for the item being weighed. If the item information does not match, the point of sale terminal halts the current purchase transaction until a supervisor intervenes.
