At least with Visa and MasterCard, fraud protection is exactly the same for both debit and credit.The protections are better and easier against fraud is one of my biggies. Get hacked, make a call, done, try that with a DC. Went without a CC for years, then got one for travel now I see the dollars rolling in on the same items I would have purchased anyway on the DC and got nothing.
Local retailers tell me 80% of their sales are CC.
NEVER USE A DC AT A RESTAURANT!
Ironically enough I am dealing with this right now. Huntington Bank caught 2 bogus charges this week. I already have the funds back. Card was cancelled and new one is en route.
