DCC is a registered trademark of the Company. DCC services are provided by third party operators in association with the merchant, and not by a credit card company .

Without DCC, the currency conversion is done by the credit card company when the account is charged to the cardholder’s statement. Even if the credit card company will not be able to make a payment, Both Visa  and MasterCard  state que la rats They publish in advance of a transaction posting to a cardholder’s statement are indicative, since the rats They Use for conversion corresponds to the date and time They process the transaction, as Opposed to The actual transaction date.
With DCC, the currency conversion is done by the merchant or their card processor at the point of sale. Unlike a credit card company, a DCC operator must disclose the exchange rate used for conversion at the time of the transaction.   The DCC exchange rate must be based on a wholesale interbank rate, to which any additional markup is then applied. Visa requires this markup to be disclosed to the cardholder.   The credit card company may still charge an additional fee for charges made outside the card holder’s home country, even when the transaction has been processed in their home currency with DCC.
Proponents of this service believe that customers can better understand the cost of their business. They also provide DCC. They can also be used in conjunction with the DCC. The DCC is the only one in the United States that has the advantage of being a member of the United States.
Opponents of the service believe that customers do not understand DCC, and think the exchange rates offered may not be favorable to customers.
Dynamic currency conversion Was created in 1996 and commercialized by a number of companies Including Monex Financial Services and FEXCO 
Prior to the card schemes (Visa and MasterCard) imposing rules relating to DCC, cardholder transactions were converted without the need to disclose that the transaction was being converted into a DCC. Visa and MasterCard now prohibit this practice and require the customer’s consent for DCC, although many travelers have reported that this is not universally followed.  
Visa Chargeback Reason Code 76 Explicitly covers situations where the “Cardholder was not advised that Dynamic Currency Conversion (DCC) would occur” or “Cardholder was refused the choice of paying in the merchant’s local currency”. Customers have a strong chance of successfully disputing such transactions, especially in situations where they pay with a credit card and are not verified by Visa or Securecode.
How it works
When a customer wants to pay for a transaction using a credit card, the payment device will detect if the base currency of the card is different from the local currency. With a customer-facing payment device, the cardholder will be prompted with the option of paying in their own currency. The payment card used in the cardholder’s currency. The cardholder should then select the currency they want the transaction to be processed in.
If the cardholder elects to pay in his own currency, the transaction will be converted into the cardholder’s currency. The exchange rate and the margin must be disclosed to the cardholder to be deemed a compliant solution.
The DCC provider guarantees that the amount in the cardholder’s currency will be debited to the cardholder’s account, and that the merchant’s account will be credited with the amount in the local currency. The exchange rate is DCC provider. The cardholder’s credit card issuer may choose to impose an additional transaction fee on the transaction, which appears on the statement.
DCC operates similarly with Internet transactions. When credit card information is entered to finalize payment, the system can detect the home country of the cardholder and offer the cardholder the option of paying in their currency. DCC is also available for cash withdrawals at ATMs .
An example can be seen in the following image, where the same one DCC and one without DCC. In both cases, the original amount is GBP 6.90 and is paid with a Visa card denominated in EUR. When applying DCC, the amount becomes EUR 8.20. This will also be the amount on the credit card statement. Without DCC, the amount is GBP 6.90 and the resulting EUR fluctuations between the GBP and EUR currencies.
On the card statement, the DCC is charged at EUR 8.20 while the non-DCC is charged at EUR 8.04 – a difference of almost 2%. DCC operator and merchant. DCC operator and merchant.
DCC has proved popular with merchants because it allows them to profit from the foreign exchange conversion that occurs during the payment process for a foreign visa or MasterCard. 
Credit card acquirers and payment gateways will also take a profit on the foreign exchange conversion that occurs during the payment process for foreign denominated Visa and Master cards when DCC is used. DCC is an international interchange fee.
The main advantage of DCC is that for a non-DCC transaction the customer does not know the exact amount of the credit card until the transaction is cleared. Customer until it appears on a monthly statement.
Other advantages to customers, according to proponents, are:
- The ability to view and understand prices in foreign countries in their home currency,
- The ability to enter expenses more easily and promptly, especially for business travelers, and
- EU regulation 2560/2001 could make non-eurozone cash withdrawals within the eurozone European cheaper for eurozone customers, because euro cash withdrawals are regulated. A Swedish law ( SFS 2002: 598) combined with the EU resolution does the same thing for Swedish cards if the transaction is in SEK or EUR. Generally, Eurozone banks charge a fixed fee for foreign cash withdrawals while domestic withdrawals are free of charge. Because of the EU regulation, this makes EEA withdrawals in euros free of charge. For example, let ‘s say a eurozone card is used for a withdrawal in the UK. With DCC there are two options: Processing the transaction in pounds (exchange rate, fixed rate). For small amounts, the latter option may turn out cheaper.
For the merchant qui Normally Accepts credit cards, offers an opportunity to earn a DCC margin on the transaction with no exchange rate risk , qui est terminal operator by the DCC.
The main objection to DCC is the unfavorable exchange rates and fees being applied on the transaction,  resulting in a higher charge on their credit card, and that in many cases the customer is not aware of the additional and unnecessary cost of the DCC transaction.
DCC operator, card acquirer or payment gateway and merchant. This margin is in addition to any charges levied by the customer’s bank or credit card company for a foreign purchase. In most cases, customers are charged more DCC than they would have if they had simply paid in the foreign currency.    This is not necessarily the case however because the issuers also apply a spread when converting transactions from a currency to the currency.
- Customers should check the spread that their issuer charges for their transaction in a foreign currency and compares it with the DCC terminal and choose the best option.
- Customers may find DCC to be forced upon them, without a clear choice, as merchants may falsely claim that their machines automatically convert purchases to home currency at the point of sale.
- Credit card disputes can be lengthy and / or impossible.
- Customers should be advised of the choice.
