ATM Card Trapping (Lebanese Loop) Scam

ATM card trapping, widely known as the Lebanese loop, is a physical attack on cash machines that pairs a mechanical trap with old-fashioned shoulder-surfing. The trap is a small, cheap device — a strip of film, a plastic sleeve, or a looped snare — inserted into the card slot ahead of time. It lets your card go in but grips it so the machine cannot return it. The screen behaves as though the card has been retained, and to you it looks exactly as if the bank has swallowed it. The second half of the scam is human. A stranger loitering nearby, or approaching as you struggle, offers advice: press cancel a few times, re-enter your PIN, try again. What they are really doing is watching your fingers on the keypad. Once you give up and walk away to phone your bank, they extract the device with your card still snagged in it, and now they hold both the card and the PIN. The distinction that matters most is that your card was never captured by the bank at all — it is sitting in a thief's sleeve inside the slot.

The operator prepares an ATM in advance, sliding the loop or sleeve deep into the card slot so its ends sit hidden or trimmed flush, sometimes secured with a tiny tab only they can grip. A card entering a trapped slot reads normally at first, so the machine may ask for your PIN and appear to begin the transaction before failing to eject the card. From your side there is no visible clue: the card is gone, the screen is unhelpful, and your instinct is that the machine has malfunctioned. This is when the accomplice appears, or reveals themselves from nearby. They act concerned and knowledgeable, urging you to re-enter your PIN or try a particular button sequence to 'release' the card, positioning themselves to see the keypad as you comply. Nothing they suggest can work, because the card is physically snagged, but each attempt hands them another clear view of your PIN. Eventually you conclude the card is lost inside the machine and leave to report it, often reassured by the stranger that this is the right thing to do. As soon as you are out of sight, they pull the concealed device — and your card with it — and use the PIN they memorised to withdraw cash before you can freeze the account.

The scam succeeds because a retained card is a completely ordinary event; real ATMs do capture cards for legitimate reasons, so a swallowed card triggers no alarm. That familiarity disarms you at the exact moment a stranger steps in with plausible help, and gratitude lowers your guard toward someone who is really reading your keypad. The frustration and mild embarrassment of a stuck card also narrow your focus onto the machine and away from the person beside you. Crucially, victims believe the bank now holds the card, so the sense of urgency to protect it is muted — you plan to call in the morning rather than treating it as theft in progress. That false reassurance buys the thief the minutes they need to recover the card and drain the account before it is blocked.

This machine does it all the time — just put your PIN in again and press cancel three times, it'll spit the card back out.

Don't worry, the bank keeps the card safe. Go call them in the morning, there's nothing you can do tonight.

Try entering your PIN one more time while I hold the button here — that usually works.

You cannot reliably confirm a loop by looking, so treat any swallowed card as a possible trap rather than a bank retention. Before inserting your card, give the slot a gentle tug and a wobble; loops and sleeves are often loose, protruding slightly, or leave a lip of film or tape around the mouth of the reader. If your card is retained, act as though it has been stolen this second: call the number printed on the machine or your bank's official app immediately and cancel the card from where you stand, not later. Do not accept help, do not re-enter your PIN because someone suggests it, and do not walk away leaving the card behind while a stranger lingers. If anyone nearby is unusually invested in your stuck card, that interest is itself the warning sign.
