Payment scams in Thailand, and the rule that catches all of them.

The rule

Urgency plus cash equals a problem. Any situation in which a stranger needs you to decide immediately and to pay in cash is either a scam already or is about to become one. Legitimate businesses in Thailand will wait ten minutes while you think, will let you come back tomorrow, and will take a card or a transfer. The pressure is the product. Once you have that rule you barely need the list below, because every item on it is a variation: the damage claim that must be settled now, the gem promotion that ends today, the taxi whose meter is broken. Slow the transaction down and it stops being profitable.

The second rule follows from the first. You are allowed to walk away. Nothing about being a guest in someone else's country obliges you to complete a transaction you have become uncomfortable with, and politeness is not a reason to hand over money. Thai social norms strongly favour calm, and a scam that depends on escalation collapses when the other party simply declines, stays pleasant, and telephones someone.

Card skimming and the ATM

Skimming has declined with chip cards but has not disappeared, and Thailand's exposure is concentrated where you would expect: standalone machines in nightlife districts and on tourist strips, rather than machines inside bank branches, hospitals, hotels and malls. The apparatus is a reader fitted over the card slot and a pinhole camera or an overlay capturing the keypad. The defence is unglamorous and effective. Use machines inside a staffed building, during banking hours. Look at the slot and the keypad before inserting anything and walk away from anything loose, raised, discoloured or ill fitting. Cover the keypad with your other hand every single time, which defeats the camera even where the reader has succeeded.

The merchant version is a card taken out of your sight and run through a second device. Insist the terminal comes to your table, which is standard practice here, and keep the card in your hand until it enters the machine. The detection layer matters as much as the prevention layer: turn on transaction notifications before you travel and read your statement daily. A skimmed card is typically tested with a very small transaction before anything large happens, so a strange fifty baht entry is the alarm, not a curiosity. Freeze the card in your banking application the moment you see one, then telephone your issuer.

The QR problems

Thailand's QR rail is well built and the frauds around it target people rather than the system. The first is the overlaid code: a fraudulent sticker pasted on top of a genuine merchant's printed code, so that a payment intended for the shop goes elsewhere. It is more a problem for Thai payers than for visitors, but the lesson transfers: check the receiving name and amount on your confirmation screen before approving anything, and be suspicious of a code stuck on top of another code.

The second is the closed loop offer, and this one does target visitors. A stranger, or occasionally a small merchant, notices you cannot pay by QR and offers to pay your bill from their own phone if you give them the cash. Sometimes the amount asked for is inflated. Sometimes the payment is never actually made and the confirmation screen you were shown is an old one or a fake. Sometimes it is simply an unlicensed exchange transaction at a rate chosen by them. Decline it as a category. If a Thai friend, host or colleague you actually know pays a small bill for you, reimburse them and think nothing of it; that is a different thing entirely. A stranger with a phone is not a payment service.

Exchange counters and the rate that was not the rate

Licensed exchange counters in Thailand are competitive and generally straightforward, and the frauds cluster at the edges. The recurring ones are a headline rate on the board that turns out to apply only to a denomination you are not holding or an amount far larger than you are changing, a commission that appears after the rate has been agreed, a short count in the handover, and the street changer who approaches you offering better than the board. Each is defeated by the same behaviour: use a licensed counter, confirm the exact rate for your exact notes and amount before anything changes hands, ask whether there is any charge on top, take the printed receipt, and count the notes yourself before leaving the window. Never change money with a person who approached you.

Transport

The taxi games are the most common annoyance and the least dangerous. A driver declines to run the meter and quotes a flat fare, usually two or three times what the meter would produce. A driver takes an eccentric route. A driver announces that your destination is closed today, or under renovation, or only open to Thai people, and proposes an alternative, which is invariably a shop, a tailor or a gem dealer paying him a commission.

• Use the ride hailing applications wherever possible; the price is agreed in advance and the journey is recorded
• In a street taxi, ask for the meter before getting in, and get out politely if the answer is no; another will stop within a minute
• At the airport, use the official public taxi rank or a prearranged car, and ignore anyone who approaches you in the terminal
• No attraction in Thailand is ever closed today in a way a stranger on the pavement knows about and you do not
• Never accept an unsolicited tour, shopping trip or temple visit proposed by a driver
• Agree the price of a tuk tuk before departure, and treat it as entertainment rather than transport

The jet ski, and the damage claim

This one deserves its own section because it is the scam most likely to escalate. A jet ski, motorcycle or small boat is rented on a beach with a passport or a deposit left as security. On return, the operator points out damage, sometimes pre existing and sometimes invisible, and demands a large sum in cash immediately, occasionally with several people present and occasionally with an official arriving to encourage settlement. The demand is designed to be large enough to hurt and small enough to pay rather than fight, and the passport in their drawer is the leverage.

The prevention is complete and takes two minutes. Rent only through your hotel or a provider your hotel or our office will stand behind, so that there is a relationship and a reputation at stake. Never leave a passport as security; offer a copy, a deposit or a card imprint instead, and if a passport is the only accepted security, do not rent. Before you take the craft out, walk around it filming continuously, close on every scratch, with the operator in frame, and keep the video. If a claim is then made, do not pay, do not argue on the beach, and do not let anyone keep your documents. Telephone the Tourist Police on 1155, telephone your hotel, and telephone our office if you are a client. The presence of a third party on the line ends most of these conversations quickly.

Gems, tailors and the friendly stranger

The oldest scam in Bangkok is the well dressed, well spoken stranger near a major temple who explains that it is closed for a ceremony, that today happens to be the last day of a government gem promotion, and that a tuk tuk will take you there for almost nothing. The gems are worthless, the export paperwork is meaningless, and the refund does not exist. Its cousin is the tailor operation running on the same commission structure, which is not a fraud exactly but is a poor suit at a good price masquerading as the reverse. Thailand has genuinely excellent tailors and genuinely excellent jewellers, and every one of them will still be there tomorrow, takes cards, and does not need to find you on a pavement. The rule holds: no unsolicited stranger outside a major attraction has good news.

If it happens anyway

• Stop paying immediately, and do not let the fact that you have already paid something pull you into paying more
• Do not escalate physically or verbally; stay calm and involve a third party by telephone
• Call the Tourist Police on 1155, which operates in English and exists precisely for this
• Freeze the affected card in your banking application first, then telephone your issuer to report and reissue
• Get a police report from the local station if you will need one for insurance or for a card dispute
• Keep every receipt, photograph, video and message; disputes are won on evidence
• Tell your hotel, because they know the local operators and the local police station and can help
• Contact your embassy if a passport has been taken or retained by anyone

Scam patterns change and new ones appear, particularly around digital payments and messaging. Report incidents to the Tourist Police on 1155 and to the local police station, notify your card issuer immediately, and verify any operator or rental provider through your hotel or our office before handing over money or documents.
