I got a call three weeks ago from Visa (not my credit union) and told me they canceled my debit card for fraudulent activity in Michigan. I live in Illinois. I asked them what was suspicious, they said three different purchases at the same store ( Meiyers ?) in the same day for over a hundred dollars each time. I asked how they knew it wasn't me because we travel a lot. They said they track my spending habits and I never did that before. That store doesn't require pin numbers on debit, you can just sign the name on the card. So..be careful where you shop and they just let you sign and tell them that is unacceptable!!
