I agree that credit cards are theoretically safer against fraud than debit cards because it's not your money that's being stolen. But I also think that the inherent risk of using debit cards is exaggerated. The card is just a piece of plastic. The degree of risk is a function of the issuer's policies. And in my direct experience, reputable issuers will make things as painless as possible after a fraud event.
I had several debit and credit cards compromised a few months ago. It was a pain in the ass because of all the automated payments I had to edit, but I suffered no losses other than annoyance. Neither was there any difference (from my POV) between credit and debit cards with regard to the process of dealing with the aftermath.
Part of the reason I suffered no losses was that I had transaction notifications enabled. If you dig deep enough into most card issuer's Web sites, you'll find an option for the issuer to email and/or text you any time certain things happen. I choose to be notified any time a purchase is made that exceeds the lowest transaction amount the system will accept (typically either $0.01 or $1.00). So when my PayPal debit card was compromised, I knew within seconds. I immediately called PayPal, and they immediately refunded the money, canceled the card, and ordered a new one for me.
In the case of my credit union, their security department caught a suspicious transaction, declined it, temporarily blocked the card, and called me on the phone to follow up. Once I confirmed that the charge was fraudulent, they canceled my cards and stamped out new ones for me, which I picked up at the credit union that same day.
Because I didn't yet know where the cards had been compromised, I also canceled some other cards that I'd used recently as a precaution. There was no difference in the process between debit and credit cards.
As for reasons to use a debit card, again, they depend on the card and the issuer. Obviously, the issuer wants you to use their card because they want the swipe fees, so pretty much all reputable issuers provide zero fraud liability. What they provide beyond that can vary widely, however. For example:
- The debit cards associated with my business and personal accounts at my credit union provide zero fraud liability, but no particular advantages beyond that. They do have good fraud detection, and they did make the process of dealing with the aftermath of the compromise easy and painless. I had replacement cards within less than an hour. But there are no particular benefits or incentives attached to using the cards.
- My PayPal debit card provides zero fraud liability plus pays 1 percent cash back on most purchases. This adds up pretty quickly if you use the card for big purchases or routine smaller purchases (fuel, utility bills, etc.). PayPal also has pretty impressive fraud detection. They once called me on my cell phone within a minute or so after I'd made an ATM withdrawal in San Diego. I'd charged the original airline tickets to the PayPal debit card, but then extended my trip. PayPal's system immediately flagged as suspicious the ATM withdrawal in San Diego after I should have been back in New York.
- My Fidelity Cash Management Account debit card provides the broadest array of benefits of any debit card I've ever had. In addition to zero fraud liability, it provides extended warranties on most purchases, damage insurance on car rentals (up to the full value of the rental car), various types of travel insurance and travel-related services, and a bunch of other benefits. The leaflet describing all the benefits is six pages of fine print. In addition, when used at an ATM, Fidelity reimburses the card holder for the ATM fees.
In the end, I think it comes down to how much the issuer wants you to use their account and their card. They all want you to keep as much money as possible on deposit with them, and they all want the swipe fees. How generously they go about incentivising those things varies widely, but the zero fraud liability is pretty much a given. Especially nowadays, with all sorts of review and gripe forums out there on the Interwebs, the last thing a reputable issuer wants is a reputation for making the aftermath more painful for victims of card fraud or identity theft.
