Premium Card (contactless signal)

Hi everyone! First I would like to state that its great to be part of Revolut as a user. The reason of my post is because it happens to experience something a lot of times by using my Premium Card so I would like to make a suggestion. The issue I am experiencing is that a lot of times when I use my Premium card to pay the employee of the store inserts my Card in the machine instead of using the contactless technology. Sometimes I even say to them to use it and their response is that there is no contactless signal in your card. The fact is simple just because the contactless signal is on the back of the card it is not visible. It may be better if this would be transferred on the front of the card so it can be used more frequently.
