How do they do that?I haven't used a CC or debit card at wal-mart for a while now,but I use one locally often.Everywhere I use it there is a keyboard that I have to slide it through and enter the info,the cashier never has the card?

The few times I have to hand it over,I always get a reciept to sign before the transaction is final..like at sears or a resturant.
