Tourist destinations like Cancun, Tulum, Cabo San Lucas, and Puerto Vallarta are full of hidden exchange rate markups. Follow these 3 rules to protect your travel budget:
When withdrawing pesos at Santander, BBVA, or Banorte ATMs, the machine will ask: "Accept ATM conversion rate?" Always press DECLINE. The ATM will still give you pesos, but your home bank converts it at the wholesale rate, saving you $15–$40.
When the card reader asks "USD or MXN?", always select MXN. Charging in USD adds a 7% to 12% DCC bank markup.
Under Mexican Federal Consumer Law, adding mandatory tips (propina) to your receipt is illegal. Tipping is strictly voluntary (10% to 15% standard).
Tipping culture in Mexico differs from the US. Restaurants often cater to tourists with inflated suggestions or illegal automatic gratuity. PesoDolar provides authentic calculation and consumer protection built-in:
Calculates standard Mexican propina simultaneously in Mexican Pesos (MXN) and US Dollars ($).
Instantly divides the check between 1 to 20 people with exact per-person amounts in both currencies.
Reminds tourists that mandatory tips are prohibited under Mexican Federal Consumer Law.

Authoritative answers on Mexican currency conversion, tipping laws, and foreign card payment best practices.
Always pay in Mexican Pesos (MXN). When credit card terminals ask whether to charge your card in USD or MXN, choosing USD triggers Dynamic Currency Conversion (DCC). DCC allows the local Mexican merchant bank to set an unfavorable exchange rate with a hidden 7% to 12% markup. When you choose to pay in MXN, your home bank processes the charge at the official wholesale Visa or Mastercard exchange rate, saving you substantial money on every bill. You can test any terminal prompt with the built-in Terminal Trap Checker in PesoDolar for iPhone.

When using an ATM in Mexico, always insert your debit card and when prompted: "Do you accept the exchange rate conversion?", press DECLINE CONVERSION. The ATM will still dispense your Mexican Pesos cash, but your domestic bank will convert the currency at the fair interbank rate, saving you $15 to $40 in fees compared to the ATM's marked-up rate. You can practice this workflow anytime inside the PesoDolar app.

It is best to withdraw Mexican Pesos directly from an official bank ATM (Santander, BBVA, Banorte) upon arriving in Mexico, and ALWAYS choose "Decline Conversion" on the ATM screen. Exchanging cash at US airport kiosks or Mexican Casas de Cambio incurs hefty 10% to 18% spreads. Use PesoDolar to verify wholesale exchange rates in real time.
Dynamic Currency Conversion (DCC) is a financial process where an overseas card machine or ATM offers to charge your credit card in your home currency (USD) instead of the local currency (MXN). While it may seem convenient, the foreign bank inflates the exchange rate by adding a 7% to 12% hidden conversion fee. Declining DCC and choosing MXN forces the charge to clear through your home bank at standard wholesale rates. Use the DCC Terminal Trap Checker in PesoDolar to protect yourself.
