Thieves are placing transparent traps inside ATM card slots to capture customers' cards unnoticed. They work with accomplices who warn of witnesses and target additional victims. Once a card is trapped, an accomplice pretends to help the confused customer, convincing them to reveal their PIN so the thief can access their account. With both the card and PIN, the thief withdraws money before removing the trap and escaping. The transparent film traps are hard to detect but can be removed by pulling on the glued edges to retrieve captured cards and stop the theft.
