Dynamic Currency Conversion (DCC)

When merchants abroad offer to charge your card in your home currency instead of local currency, usually with hidden markup of 3-7%.

Also known as: dcc, currency conversion

What You Need to Know

Dynamic Currency Conversion is a sneaky way merchants and ATMs abroad try to make extra money by offering to convert prices to your home currency at the point of sale.

How the Scam Works:

  1. You buy something in Paris for €100
  2. Merchant asks: "Pay in euros or dollars?"
  3. If you choose dollars, they convert at a bad rate (€100 = $115)
  4. Real rate would be: €100 = $110
  5. You just lost $5 (4.5% markup)

Why Merchants Love It: They get a kickback from the conversion company—typically 1-2% of every transaction. That's why they push it so hard.

Red Flags:

  • "Would you like to pay in your home currency?"
  • "Lock in today's exchange rate"
  • "See the exact amount in dollars"

The Right Answer: ALWAYS choose to pay in local currency. Let your credit card company do the conversion—they get better rates and don't add extra fees (if you have a no-foreign-transaction-fee card).

Real Example:

  • Restaurant bill: €150
  • DCC rate: 1 EUR = 1.15 USD = $172.50
  • Real rate: 1 EUR = 1.10 USD = $165.00
  • You lose: $7.50 on one meal

The Bottom Line: Dynamic Currency Conversion is a trap. Always decline it and pay in local currency. The "convenience" of seeing your home currency costs you 3-7% every time.
