How can I keep my credit card details from being stolen online? [Ask ZDNet]

As you’ve discovered, the inconvenience associated with being the victim of credit card fraud is significant. Thankfully, for cardholders in the United States, protections in the Fair Credit Billing Act mean your actual losses are limited to $50, provided you notify the card issuer as soon as you become aware of any theft or unauthorized use. Most card issuers have fraud detection capabilities that will alert you immediately in the event of a suspicious transaction and protect you from any loss. 

One important caveat here: These fraud protections do not apply to debit cards, even if the card has the logo of a major credit card issuer. The Electronic Fund Transfer Act offers similar protections if you report an unauthorized transaction within 48 hours, but after that you’re on the hook for $500 in losses, and the limit vanishes completely if a fraud goes unreported for 60 days. (For details, see this FTC page: “Lost or Stolen Credit, ATM, and Debit Cards.” 

Even with those protections, there’s always a risk with any online transaction. How do you minimize your risk? 

1. Be vigilant about sites where you use your card. Make sure the page is secure and that the merchant is trustworthy. If you don’t recognize the merchant or the site seems suspicious, think twice before entering your card details. 
2. Avoid storing your card details unnecessarily. You can probably waive this precaution for top-tier merchants like Amazon and Apple, but it’s really not that inconvenient to re-enter a card number for smaller merchants that you do business with occasionally. (Obviously, you can’t avoid this for recurring payments.) 
3. Use Apple Pay, Google Pay, Samsung Pay, or other digital wallets whenever possible. Those systems use virtual account numbers tied to your device, which means in the event of compromise, your actual card number is not revealed. (For details on virtual card numbers, see these support documents from Google and Apple.) 
4. Create your own masked card. The free Privacy.com service, for example, lets you create virtual credit cards for specific merchants. You can assign per-transaction limits or set an overall maximum charge for one of these cards, making it impossible for an unscrupulous merchant to turn a small charge into a larger one without your consent. We’ve used this service and can recommend it enthusiastically.
