Skimmers are malicious card readers that illegally gather data from a credit or debit card’s magnetic stripe. They’re often attached to a real payment terminal and allow a scammer to steal personal financial and account information. Gas pumps are a prime target!
Skimmers can be placed externally over the real card reader or internally (harder to detect) if the thief has a key to get inside the machines.
