Coincidentally, that day when I went into my grocery store to get a six pack of brew, I got carded. I handed my new little card over and the teller and rather than looking at my date of birth she started to swipe the damn thing through her credit card reader machine! I stopped her, grabbed my DL back and told her to manually enter the date as they have always done. When she explained that it is against store policy and that she 'had' to swipe any IDs that had the strip I got my keys outta my pocket and all but removed the strip from the back of my little nemesis. Handed it back to her and told her to swipe away; it is against MY policy to provide the store with my address. I don't want any damn pepsi coupons mailed to me each time I buy coke, or northern tissue coupons when I buy charmin. Nor do I want the store collecting information on how much beer I buy.
Odd. When I first got a card with the stripe, I was a little paranoid so I took a bar magnet and erased it. Actually, I don't know whether my eraser worked because nobody has ever asked to swipe my card thru a reader. I got a wallet with a plastic fold-out so if someone asks to see my id, I open my wallet and show it to them, then put it away.
