Boston – Massachusetts retail price scanners reportedly operate at a 99.8% accuracy rate. According to the Associated Press, the Massachusetts Division of Standards checked scanners at 98 different stores of 50 retailers across a wide range of verticals and discovered five overcharges out of about 2,800 individual price scans.
The highest overcharge amount was $3.80. Overcharges were assessed by comparing price indicated by the scanner at checkout to the price marked on an item or at the shelf. Each retailer that had an overcharge was fined $100 per overcharge. Accuracy improved slightly from the 2012 scanner survey, which produced a 99.6% accuracy rate.
