I am travelling a lot around the world.
What I often encountered while using the Revolut MasterCard credit card is that people do not immediately recognize that the card has Contactless support.
I assume that the reason for that is that the sign is on the back of the card and not on the front of the card.
Most of the details from the card are on the back, which I personally like. It hides the details like card number, CVN and expiry date - but it also hides the Contactless sign.
Consequence is that many insert the card into the cardreader, which prolongues the process of paying in an unnecessary way.
Hence: Please put the sign on the front of the card. It will get recognized a lot more. Many competitors have it also on the front.
