With all the stories of major retailers losing millions of credit card account numbers, you are probably scouring your monthly bills looking for fraudulent charges like a $1700 plane ticket or $1000 television you did not buy. That is a big mistake. Hackers are now using smaller transactions to garner money from hacked accounts.
This is a common way hackers commit fraud, and they can easily get away with it. Through the years, they have found it is much easier to steal a little money from a lot people, rather than a lot of money from a few people. For example, it is much easier to sneak a $10 charge on 100,000 cards than a $100,000 charge onto 10 cards, and in the end, the hackers end up with the same amount.
Large charges for electronics or airfare stick out like a sore thumb on a credit card bill. Busy consumers are much less likely to spot a small charge, or they might even decide a tiny fraud is not worth the phone call to get it removed and to face the hassle of getting a new card.
