POS and ATM Card Scams in Nigeria: The Common Tricks and How to Avoid Them

POS agents are everywhere in Nigeria, on street corners, in markets and outside banks, and they make cash easy to get. But fraudsters have learned to exploit them, and ATM galleries too. Victims have lost hundreds of thousands, even over a million naira, in minutes.

Here’s how the common scams work, and how to protect your money.

Scam 1: The ATM card swap

Vanguard reported in December 2025 on rising card-swap fraud, often during weekends and public holidays when banks respond more slowly. The pattern:

1. Your card gets “stuck” in the ATM, or you have trouble with the machine.
2. A “helpful” stranger offers assistance and watches you enter your PIN.
3. During the distraction, they swap your card for a similar-looking one.
4. Accomplices withdraw money quickly through POS terminals before you can block the card.

Real cases from the report:

• One family lost ₦255,000 in three transactions within about six minutes.
• Another customer had ₦1,197,000 withdrawn in a single POS transaction while his card was supposedly still trapped in the ATM.

Scam 2: PIN theft at POS stands

At busy POS points, fraudsters may:

• watch or record you entering your PIN
• swap your card while handing it back
• ask you to enter your PIN more than once, claiming the first attempt “failed”

Scam 3: Dishonest POS operators

Some operators may overcharge, process unauthorised transactions, or charge for a withdrawal that “failed” while the money actually left your account.

Scam 4: “Your card is blocked” calls and texts

Calls or messages claiming to be from your bank, asking for your card number, CVV, PIN or OTP to “unblock” or “upgrade” your card. Banks like Access Bank warn customers never to share their OTP, PIN, CVV or card details, and banks will never ask for them.

Ten ways to protect yourself

1. Cover the keypad with your hand every time you enter your PIN.
2. Never accept “help” from strangers at an ATM. If your card is stuck, call your bank from your own phone, not a number someone gives you or one stuck on the machine.
3. Check it’s your card before you put it away: name, last digits, bank.
4. Use trusted POS agents, preferably in a shop with a fixed location, not a random roadside stand at night.
5. Never enter your PIN twice without checking your bank app to see whether the first attempt went through.
6. Collect a printed receipt and check your bank app immediately after each transaction.
7. Turn on transaction alerts (SMS and in-app) so you notice unauthorised debits instantly.
8. Set daily withdrawal and POS limits in your bank app.
9. Save your bank’s fraud number somewhere other than your phone.
10. Avoid ATMs in isolated places, especially late at night or on public holidays.

If your card is swapped, stolen or stuck

1. Block the card immediately in your bank app, by USSD or by calling your bank’s official customer-care line.
2. Freeze your account if your bank offers it.
3. Change your PIN and online banking passwords.
4. Report the incident in writing to your bank (email or branch) and keep the reference number.
5. Report to the police, especially if money was taken. Ask the bank to secure CCTV footage quickly.
6. Escalate to the Central Bank of Nigeria’s consumer protection channel if your bank doesn’t resolve your complaint.

For POS agents: protect yourself too

POS agents also face growing risks, including robberies after cash withdrawals and fake transfer alerts. Agents should:

• confirm transfers in their own bank app before paying out cash (see our fake alert guide)
• vary times and routes when moving cash
• keep minimal cash at open stalls
• use CCTV where possible
