In certain countries, for example Russia, the U.S., and some countries in Asia, a merchant is permitted to charge a convenience fee to the customer. The fee must be a flat fee (not a percentage of the transaction amount), clearly disclosed, and represent payment for the convenience of paying through an alternate payment channel (such as online) that is different than the merchant’s normal payment channel (for example sending a check through the mail or paying in person).
Certain merchants (for example, government, education) in Canada, Egypt, Russia, and the U.S. are permitted to assess service fees on Visa Card transactions
