I have two cards in my wallet that are identical except for the account. They have braille marks but you can't differentiate the account number by touch as the number is only printed on the cards. When the cards get sent by my bank they have a sticker on them to say that you need to activate this card first. I take the sticker off only one card and leave it on the other but it is hard to tell by touch that it is there.
