Detectives from the Montgomery County Police Department Financial Crimes Section are urging residents to be aware of credit card skimmers. Card skimming is where criminals use small credit card reading devices, called skimmers, to illegally collect data from the magnetic stripe of credit or debit cards. These devices are often installed discreetly on ATMs, gas station pumps, or point-of-sale terminals. The stolen data is then used to create counterfeit cards or for unauthorized transactions, resulting in financial losses for cardholders.”
