Question 1

What is the "Pemex Gas Pump Overcharge" scam in Cozumel?

Accepted Answer

Attendants at Cozumel's Pemex gas stations fail to reset the pump to zero before beginning to fill tourists' rental vehicles, charging them for the previous customer's fuel plus their own. This scam has been reported across multiple dedicated TripAdvisor threads over many years, with tourists renting cars, golf carts, and scooters consistently reporting being charged two to four times the expected amount. A common distraction technique involves one attendant blocking the display while another pumps. Exit your vehicle and physically verify the pump display reads 0.00 before the attendant begins pumping. State the peso amount you want to pay ("cien pesos," etc.) before pumping starts. If the pump was not reset, refuse to pay the full amount and ask for the station manager. Photograph the pump display at start and end if possible.

Question 2

What is the "Credit Card Overcharge at Souvenir Shops" scam in Cozumel?

Accepted Answer

Retailers in Cozumel's tourist shopping zone — particularly jewelry, vanilla, and souvenir shops near the cruise piers — have been documented adding unauthorized charges to credit cards after the transaction is complete. Reported on TripAdvisor, Cruise Critic, and ScubaBoard, these include rounding up purchase totals, adding fabricated "exchange rate" surcharges of $50 or more, and in some cases cloning card data for later fraudulent use. Unlike ATM skimming, this fraud occurs at the point of sale when the card is physically handed over to a shop employee. Pay in cash at all souvenir and retail shops in Cozumel rather than using a credit card. If you must use a card, watch the terminal while the transaction is processed and never let an employee take your card out of sight. Review your card statements carefully within 48 hours of any purchase. Dispute any unrecognized charges immediately with your card issuer.

Question 3

What is the "ATM Card Skimming Devices" scam in Cozumel?

Accepted Answer

Card skimming devices are placed on standalone ATMs throughout Cozumel, particularly on machines located in small shops, convenience stores, and tourist-facing kiosks along the waterfront boulevard. Victims typically discover unauthorized withdrawals of several hundred dollars days or weeks after leaving the island. A documented incident at a Banamex branch confirmed skimming equipment had been installed and was observed by bank officials only after multiple tourists reported losses. Use ATMs located inside major bank branches during business hours only — Banamex, HSBC, and Santander branches in San Miguel are preferable. Cover the keypad with your free hand when entering your PIN. Check for any loose plastic overlay on the card slot before inserting. Monitor your bank account daily during your trip.

Question 4

What is the "Short-Changing in Peso-Dollar Transactions" scam in Cozumel?

Accepted Answer

Vendors and some restaurants in Cozumel accept US dollars but apply unfavorable exchange rates and return change in a mix of pesos and dollars that is difficult to verify quickly. Some cashiers short-change tourists who are unfamiliar with Mexican peso denominations. Pay in Mexican pesos whenever possible to avoid unfavorable exchange arithmetic. Count your change carefully before leaving the counter. Keep small peso denominations available for market transactions.
