This is no problem. I have many credit cards with cards, which are very reliable. But remember, don't let the dealer take your cards out of your sight. Usually he just takes a picture and doesn't need to take it with him. So, for the sake of safety, you should look at the photos he took before taking them away! Also, it is best to set the transaction password, and don't set the password-free consumption for the sake of saving trouble, so if you lose it and don't find it in time, you will be in big trouble!
