Stop & Shop Supermarkets have reported that several of its stores have been hit by thieves who tampered with checkout-lane card readers in an effort to steal shoppers' pin numbers.
Stop & Shop became aware of the problem when banks noticed fraud on cards used at their stores. The bank then notified the store.
After an investigation, it was discovered that the keypads shoppers use to submit PIN-based transactions had been tampered with to allow information to be stolen.
