Door Skimmer + Hidden Camera = Profit
If an ATM you’d like to use is enclosed in a vestibule that requires a card swipe at the door, it might be a good idea to go find another ATM, or at least use something other than a payment card to gain entry. Thieves frequently add skimmers to these key card locks and then hide cameras above or beside such ATMs, allowing them to steal your PIN and card data without ever actually tampering with the cash machine itself.
