A debit card with the Visa logo has the same benefits as a Visa credit card.
I hired a company to do a service and used my Visa debit card...they did not follow through on the service and I requested a refund...they kept ignoring it and would not give me a refund...I contacted Visa and they withdrew that money from them and returned it to my account. They will do that with unauthorized use also, just like a credit card.
Also, something everyone may not know, YOU can set a limit on your debit card for purchases if you are concerned about someone else using your card, authorized or not...of course there is always the $300 per day limit on atm withdrawals.
This is my understanding as well (per Dave Ramsey).
