Let us start by saying that If you want to pay for one of your products but the Credit Card is in a different currency than the currency in which we sell our tours, then you have 2 options. This can be selected on the screen where you enter your credit card details by selecting "view currency conversion options":
Option A
TrekkSoft does the currency conversion to accept the customer's currency, exchanging that into the currency in which we operate our tours. This is called dynamic currency conversion since we display the actual USD price (Or whatever currency your card is in) to you at the time of booking and this is the amount which is debited from your card without any further conversions or charges.
Option B
The card issuer ( your bank) does this currency conversion and applies a commission and processing fee. So this is when a tour is in EUR for example, and you are charged in EUR even though your credit card account is in USD. So your bank gives you an exchange rate which you will only see on your monthly statement.
In either case, as we are not a bank, the conversion is not the same as you would see on the likes of xe.com since these are the wholesale currency values, these rates are not available to anyone in reality.
The retail rates are always higher since there are differences in buying selling rates, and there are commissions and transaction fees when exchanging currencies. Whatever currency you pay, we will receive the amount as displayed in EUR
