This happened last year too,but it's already become a bigger problem this season.
The Department of Homeland Security is warning holiday shoppers of a simple, yet effective, holiday scam involving gift cards.
Thieves have been copying the numbers and codes from the backs of the gift cards while they're still in stores, then waiting until they're purchased and activated before using the information to make purchases. Because the cards are usually purchased as gifts, the theft isn't discovered until the recipient tries to use it.
To prevent gift card theft, DHS officials recommend checking to make sure the protective scratch-off area on the back of the card hasn't been tampered with before buying it. They also suggest buying gift cards that are kept behind store counters, whenever possible.
