Dynamic currency conversion (DCC) is a financial service used in international transactions, when a customer from one country makes a credit or debit card purchase in another. DCC allows the transaction to be processed at the point of sale in the currency of the cardholder's home country. The global credit card payments market is forecast to jump from around US$679 billion in 2025 to about US$1.5 trillion by 2035, and cross-border payments are an important piece of that growth.

Below, we'll explain what businesses should know about dynamic currency conversion, including how it works, how it compares with traditional currency conversion, and the pros and cons of implementing dynamic currency conversion.

Key takeaways

• Dynamic Currency Conversion (DCC) lets a merchant offer international cardholders the option to pay in their home currency at checkout, with the exchange rate and any markup determined by the merchant's DCC provider.

• DCC typically costs more than letting the customer's bank handle conversion. The exchange rate includes a markup plus bundled fees.

• Cardholders should be given a clear, informed choice between paying in their home currency (DCC) or the local currency, with the exchange rate and fees disclosed up front; auto-opting customers into DCC is considered bad practice and can damage trust.

How does dynamic currency conversion work?

DCC provides cardholders with a convenient and immediate understanding of transaction costs in their home currency, though it might involve higher costs because of exchange rate markups and fees. For businesses and financial institutions, DCC offers a chance to earn additional revenue. Here's how it works:

The DCC process

• Card detection: When a customer uses a foreign credit or debit card at a business's point-of-sale (POS) system or an e-commerce platform, the system identifies the card's country of origin.

• DCC offer: The business's system, equipped with DCC technology, automatically offers the cardholder the option to complete the transaction in their home currency. The amount includes the conversion rate and any additional fees involved in the conversion.

• Customer's choice: The cardholder can accept the DCC offer and pay in their home currency or decline it and pay in the local currency.

• Transaction completion: If the customer accepts the DCC offer, the transaction is processed, and the card is charged in the cardholder's home currency using the displayed exchange rate. If the cardholder declines the DCC offer, the transaction is processed in the local currency, and the cardholder's bank will convert it using the bank's exchange rate.

Roles and benefits

• Businesses: Businesses benefit from DCC by earning additional revenue through commissions or fees associated with the currency conversion process.

• Financial institutions: Banks or financial service providers that offer DCC set the exchange rates and fees. These rates often include a markup over the standard exchange rate.

Technological integration

• Payment processing technology: DCC technology enables the automatic detection of foreign cards and real-time currency conversion, making DCC an easy option at POS systems and online.

• In-person and e-commerce integration: DCC is integrated into modern POS systems and online payment gateways, letting businesses offer this service to international customers in store and online.

For example, consider an American tourist in Italy who wants to buy an item that costs €100. The in-person payments processor recognises the credit card as American and offers to charge US$120 (which includes the DCC exchange rate and fees). The tourist can choose to pay US$120, knowing the exact cost in their currency, or pay €100, leaving the conversion to their bank.

Dynamic currency conversion vs traditional currency conversion

Dynamic currency conversion and traditional currency conversion are two distinct methods that are used in international card transactions. Each has its own implications for exchange rates, fees, customer choice and the business's profit. Here's how they differ:

Differences in exchange rates and fees

Dynamic currency conversion

• Exchange rates: The exchange rates in DCC often include a markup over the daily bank exchange rate. This markup is a combination of the currency conversion fee and a profit margin for the business or the DCC provider.

• Fees: DCC transactions typically involve additional fees, which are bundled into the exchange rate offered to the customer. These fees can vary depending on the businesses and the DCC service provider.

Traditional currency conversion

• Exchange rates: In traditional currency conversion, the exchange rate is determined by the customer's bank or card issuer after the transaction is processed. This rate is usually closer to the interbank exchange rate, which tends to be more favourable to the customer.

• Fees: Traditional conversions might include foreign transaction fees the customer's bank charges. These fees are usually a percentage of the transaction amount and are separate from the exchange rate.

Impact on customer choice and experience

Dynamic currency conversion

• Immediate clarity: DCC offers immediate clarity on how much a transaction will cost in the cardholder's home currency. This can be particularly appealing for those who prefer to know the exact cost up front without worrying about future exchange rate fluctuations.

• Potential for higher costs: Because of the higher exchange rates and bundled fees, customers might end up paying more than they would with traditional currency conversion. A 2017 study from the European Consumer Organisation found that customers using DCC in Europe paid between 2.6% and 12% more, highlighting why customers are often advised to opt out of DCC.

Traditional currency conversion

• Potential savings: Customers might save money because of more favourable exchange rates and the possibility of lower total fees.

• Uncertainty in costs: The exact cost in the home currency is unknown at the point of sale and will depend on future exchange rate fluctuations and bank fees.

Benefits of using dynamic currency conversion for businesses

DCC offers many benefits to businesses that deal with international shoppers, including increased customer convenience and additional revenue. Let's take a look:

Convenience for international shoppers

• Ease of transactions: DCC simplifies the purchasing process for international customers by letting them see prices and pay in their home currency. This eliminates the need for mental currency conversion and provides a more intuitive shopping experience.

• Familiarity and comfort: Paying in a familiar currency can be reassuring for customers, especially in an international setting where different currencies can complicate a purchase.

• Immediate understanding of costs: DCC provides customers with the exact cost in their own currency at the point of sale, eliminating uncertainties related to fluctuating exchange rates or unknown fees the customer's bank might charge.

Transparency in currency exchange rates

• Up-front exchange rate information: With DCC, the exchange rate is presented to the customer at the time of the transaction, making it clear what rate will be used for the currency conversion.

• Informed decisions: Getting this information up front lets customers make informed decisions about whether to proceed with DCC or use the standard conversion process through their bank.

• Avoidance of hidden fees: Though DCC rates might include a markup, the overall structure of the transaction is transparent, helping customers avoid hidden fees that can sometimes occur with bank conversions.

Potential rewards and benefits for businesses

• Additional revenue stream: Businesses can earn additional income from DCC transactions, from a share of the conversion fees or from adding markups to the exchange rate.

• Better customer service: DCC can be seen as a value-added service, enhancing the overall customer experience. This can be particularly beneficial in sectors in which international transactions are common, such as tourism, hospitality, and e-commerce.

• Competitive advantage: By providing DCC, businesses can differentiate themselves from competitors who do not offer this service, potentially attracting more international customers.

• Simplified accounting: For businesses, processing transactions in their home currency simplifies accounting and financial reporting by eliminating the need to convert foreign sales into local currency.

Challenges of dynamic currency conversion

Although dynamic currency conversion offers several benefits, it also comes with a number of challenges for customers and businesses. Businesses that are considering DCC should be aware of these challenges:

Higher costs for customers

• Unfavourable exchange rates: DCC often involves exchange rates that are less favourable compared with standard bank rates. This markup can lead to higher costs for customers, making purchases more expensive than they would be if processed in the local currency.

• Lack of awareness: Customers might not be fully aware of the additional costs associated with DCC. They might use it without understanding it could be more expensive than letting their bank handle the currency conversion.

Transparency and consent concerns

• Inadequate disclosure: There are instances in which the terms of DCC (including the exchange rate and fees) are not clearly communicated to the customer, leading to confusion and potential dissatisfaction.

• Consent issues: In rare cases, customers are automatically opted into DCC without explicit consent, which is considered unethical. Customers whose transactions are processed using DCC should have chosen it themselves over traditional conversion.

Regulatory and compliance requirements

• Complex regulations: Businesses offering DCC must work through and comply with complex international financial regulations, which can be resource intensive.

• Constant monitoring: Exchange rates fluctuate continually, requiring constant monitoring and adjustment of DCC rates for businesses to remain competitive and fair.

• Visa compliance requirements: Visa requires merchants to disclose the exchange rate and any markup before completing a DCC transaction, and to offer it as a genuine opt-in rather than a default. Cardholders who weren't given that choice can dispute the charge under Visa's chargeback rules.

• Mastercard compliance requirements: Mastercard requires informed, active consent and clear rate disclosure at the point of sale. Its compliance team investigates complaints and can direct a chargeback if a cardholder wasn't given a proper choice.

• Ongoing audit exposure: Both Visa and Mastercard networks monitor DCC complaints, so businesses should be ready to show that consent was properly obtained.

Consequences for noncompliant merchants:

Merchants who violate Visa or Mastercard DCC rules – such as defaulting customers into DCC or failing to disclose the exchange rate – risk chargebacks initiated by the cardholder's bank, fines from the card network, and, in repeat or serious cases, suspension of the merchant's ability to offer DCC altogether.

Impact on customer perception

• Negative customer experience: If customers feel as though they were misled or overcharged because of DCC, it can lead to a negative perception of the business, affecting customer loyalty and brand reputation.

• Educational requirement: Businesses that use DCC must educate staff and customers. Misunderstandings or misinformation can lead to a poor customer experience.

Technical and operational challenges

• Integration with POS systems: Implementing DCC requires integration with POS systems, which can be challenging and costly.

• Currency management: Businesses need to manage multiple currencies efficiently, which can complicate accounting practices and financial management.

Market variability

• Dependence on tourism and international trade: Businesses that rely heavily on DCC might face challenges during periods of reduced international travel or trade fluctuations.
  

Dynamic currency conversion best practices

Understanding and compliance

• Regulatory compliance: Your business will need to adhere to all relevant local and international regulations regarding currency conversion and financial transactions.

• Education: Staff should be well informed about DCC, including how it works and its benefits and implications for the business and customers.

• Performance analysis: Analyse the performance of DCC in your business. Look at customer uptake, revenue generated, and any customer feedback.

Customer support and feedback

• Support channels: Provide easy-to-access customer support for queries related to currency conversion.

• Feedback mechanism: Have a system to gather and analyse customer feedback specifically about customers' experiences with DCC.

Marketing and promotion

• Targeted marketing: Consider targeted marketing that promotes the benefits of DCC for specific regions.

• Promotional offers: Use DCC as an opportunity for promotional offers, such as reduced fees for first-time users or during certain periods.

Continual improvement

• Stay informed: Be aware of changes in currency markets, technology, and regulations.

• Adaptation and evolution: Be prepared to adapt your DCC practices based on new technologies, customer preferences, and market trends.

Partnerships

• Choosing the right partner: If you're using a third-party service for DCC, choose a reputable provider with a record of transparent and fair practices.

• Negotiate terms: Work with your provider to negotiate terms that are favourable for your business and fair to your customers.

Industries that benefit most from Dynamic Currency Conversion

DCC tends to deliver a lot of value in industries with high volumes of international, in-person transactions:

• Hospitality and hotels: Frequent foreign cardholders make DCC a natural fit at check-in and checkout.

• Tourism and travel services: Tour operators, airlines, and travel agencies see consistent cross-border card use from international travellers.

• Retail in tourist-heavy areas: Shops near airports, landmarks, and popular destinations often see high foreign-card volume.

• Restaurants and dining in tourist destinations: International diners benefit from knowing the exact cost in their home currency.

• Ecommerce with a global customer base: Online retailers selling internationally can offer DCC at checkout to simplify pricing for foreign shoppers.

Industries where DCC usually doesn't fit

DCC tends to add little value – and can even create friction – in industries with mostly domestic or repeat local customers:

• Local service businesses: Salons, gyms, and other neighbourhood services rarely see enough foreign cardholders to justify the setup.

• B2B and wholesale: Business transactions are often invoiced or settled through other payment methods, making DCC largely irrelevant.

• Subscription and recurring billing: Automatic renewals don't allow for a real-time customer choice at the point of sale, which conflicts with DCC's opt-in requirement.

• Grocery and everyday retail: High-frequency, low-margin purchases from mostly local shoppers see minimal upside from offering DCC.

• Government and utility payments: These transactions are typically domestic and not well suited to a service built around cross-border card use.

For these industries, the added compliance overhead of DCC usually outweighs any potential revenue.
