A large portion of sales are going to wind up being card if they decide to take cards. My suggestion is to raise prices 10% across the board and then have a 10% discount for cash transactions if they want to do it that way. Alternately they could just go ahead and raise prices 10% across the board and just not offer a cash discount. As far as percentages of people paying with a card, I would peg it right at about 75%.
