Security experts with the European ATM Security Team (EAST) say five countries in the region this year have reported card trapping incidents. Such attacks involve devices that fit over the card acceptance slot and include a razor-edged spring trap that prevents the customer’s card from being ejected from the ATM when the transaction is completed.The typical fraud first occurs around 10 minutes after the card is captured, so if an ATM machine doesn't give you your card back, you should immediately call your bank's fraud hotline. It's a good idea to have your bank's (and credit card issuers') hotline phone numbers in your cell phone's address book. Do not have your card numbers stored on your phone - if you lose the phone, those numbers are valuable to a thief.
However, being able to speed dial your bank saying that ATM location such-and-such ate your card will let them disable it instantly.
