9 questions before choosing a credit card
How do you protect against credit card fraud?
Federal regulations limit your liability for unauthorized credit card charges to $50. Many issuers cap losses at zero dollars, provided you follow a few rules. So find out how the card would handle charges you didn't make, says McClary.
Also, does the issuer monitor usage and shut down the card if it sees out-of-the-ordinary charges or spending locations? That feature can be great if you always use the card for the same types of purchases in the same geographic area, but cumbersome if you're getting the card for travel.
