It's a good idea if you aren't worried about your privacy, because the same chip that allows you to just hold the card up also allows a few other things that might not be so great.
When all cards go to this feature I will probably use my debit card by going to a cash machine, pulling out what I think I need in a couple of days, and then, when I go shopping, pay with cash.
The card in your purse or pocket will eventually be read by machines that are inside the stores, without you actually being in them. Its something my husband an I have talked about recently with all the commercial phsing that "smooth checkout" and then everything coming to a screeching halt when someone pulls out cash.
Why do you think they are so hot to have us stop using actual money?
