The document describes how thieves steal money from ATMs using card-trapping devices. It explains that thieves work in teams, with one person placing a transparent film trap inside the ATM card slot while another acts as a lookout. When an unsuspecting customer inserts their card, it gets trapped while the thief pretends to help get it back, using this opportunity to learn the PIN. They then retrieve the card from the trap once the coast is clear and withdraw money from the victim's account. The transparent film traps are hard to detect but can be removed by pulling on the folded ends to recover a trapped card. People are advised to check for card traps and report any issues to the bank immediately.
