I can attest to the debit card protection from just last week.
Monday, someone in New Jersey/New York decided $700 of my recent tax refund would be better spent in their pocket from my debit card.
Tuesday, I get a call from some protection service of which sounded like a scam about fraudulent charges and I didn't call them back. I looked the number up online and it looked like a scam according to online testimony as well. I had planned to call the credit union the following day during business hours.
Wednesday, I get a call from my credit union about fraudulent charges before I was able to call. I went in and signed the papers stating I did not approve of the charges.
Thursday, I had my $700 back in my account. Quick and simple as that.
All taken care of by Visa, which is the logo on my debit card.
As long as your credit/debit card has the Visa logo on it you get the same services as a credit card. I experienced a problem with a purchase and called my bank and got the same service one would get with a credit card.
