ABSTRACT:
A fast retail security weighing system is disclosed whereby if a second purchased item's product code is entered before the weight corresponding to the first purchased item's product code has been measured and verified, the system will consider the weight on the scale as corresponding to the first purchased item alone, but if such weight does not correspond with the allowed weight for the first purchased product, then the system will consider whether the weight on the scale corresponds to the summation of the first and second purchased items' weights. The fast retail security weighing system may also approximate the actual weight on the scale from the rate of weight change and the instantaneous weight reading.
