There's very easy ways for hackers to steal your debit card and credit card numbers and information through computer software and a device called a skimmer.
The skimmers can be on the credit card readers at checkouts, gas pumps, ATM machines etc.
The hacker could even be standing behind you with a device in a backpack or other bag and could be skimming the information off of your credit and debit cards.
