This thing about getting Credit/debit card info from someones wallet when they are next to you, let alone a block away is news to me...
Anyway, while I do not use a debit card, I do have a few credit cards in my wallet, but they are stacked up against each other so I find it somewhat hard to believe that they could get the credit card info from my wallet & distinguish between the three all right next to each other.
Not saying it is not possible, I just am quite astonished that something like that would work.
As far as doing a check on an account... When I was talking to some friends yesterday at a restaurant/bar there was a lady there whos debit card did not work for some reason. She asked the bartender to check & see what her balance was, as the woman with the card was surprised, since there was $$ in the bank account , why it was not going thru. The bartender took the card & typed something into the register & turned & said,"Yes, there is plenty in the account.", and no PIN was mentioned or used as far as I saw. I heard the whole conversation from when the lady wanted to pay her tab & all, & the bartender seemed to be able to get the account amount on hand info without a PIN.
I do not know if a charge was made on that ladies account for the query, but I just thought I would mention this instance & that maybe it was just a mistake by someone pressing the wrong buttons for their acct. & getting yours instead. Somewhat similar to dialing up a wrong number when using long distance & the phone company doesn't know you called the wrong number & still bills you for the mistaken call, unless you complain about it.
Anyway, G'Luck! in solving your situation to your satisfaction!
