So Dave, have you used your Wells Fargo ATM lately?
I think you misunderstood Don - it has nothing to do with Wells Fargo (or the card issuing bank) - it's the ATM machines themselves. Certain machines may have been hacked/compromised.
I have not used the ATM machines in Mega since Dave posted this. I use only ATM's at actual banks with cameras.
Another tip - don't let your card out of your sight. When using your card to pay for restaurant bills, etc., make sure the merchant swipes your card right in front of you. This was becoming a big scam in the US where waiters would have card readers and sell the information to even bigger organized rings where they would make duplicate cards. It could happen anywhere - so just be careful!
