What Is Dynamic Currency Conversion? Definition, Payment Flow, and Examples
Dynamic Currency Conversion (DCC) is an option offered by the merchant or acquiring side to convert a foreign-currency purchase into the cardholder's home currency at the point of payment. This guide focuses on DCC's real role, boundaries, and common points of confusion.
Key points
- Definition: Dynamic Currency Conversion (DCC) is an option offered by the merchant or acquiring side to convert a foreign-currency purchase into the cardholder's home currency at the point of payment.
- Flow position: A cross-border transaction can involve merchant location, issuer country, processing route, or different currencies.
- Do not confuse: DCC / Cross-border Transaction
How it fits into the payment flow
For DCC, the relevant process is as follows: A cross-border transaction can involve merchant location, issuer country, processing route, or different currencies. DCC is an option at a merchant or ATM to convert into the cardholder's home currency, with local and cardholder amounts, rate, and relevant markup or fees disclosed.
A practical review of DCC should account for this: before choosing DCC or local currency, compare the displayed rate and markup with possible issuer-side fees. A familiar home-currency total is easier to read but not automatically cheaper.
Practical example
A foreign terminal displays both local and home-currency amounts with the DCC rate and markup. The customer compares and actively chooses; a home-currency display is not automatically cheaper.
