The SkimBuster is a specialized, handheld tool that can quickly identify skimmers on payment terminals in stores without shutting down the system.
A skimmer is a fake card reader that can steal customers' credit card information in a matter of seconds.
Allied Electronics donated the equipment to the All Fresh Supermarket in Bristol, after a skimming device was discovered there a few weeks ago.
It's the only grocery store in Bristol Borough, so it's where people shop every day," said Mike Vogt, CEO of Allied Electronics. "We wanted to bring back consumer confidence and do our part in this," he added.
Officials say card skimming poses an ongoing risk to local shoppers.
