The Williston Police Department is urging residents to be cautious after skimming devices were recently discovered at local gas stations. A skimmer is an illegal card-reading device that can be discreetly attached to a payment terminal, such as a gas pump. When you swipe your card, the skimmer captures data from the magnetic stripe without your knowledge. Regularly check your bank and credit card statements to quickly catch unauthorized charges. Before swiping, take a moment to inspect the pump and report anything suspicious to station staff and the Williston Police Department.
