If someone steals your credit card, they will have two things, your name and your credit card number. This enables them to act as you, meaning stealing your identity, and illegally charging things to your credit card without intent to pay for them. Protect your credit cards, social security number, and bank account numbers in safekeeping, and don't carry too much with you at one time. Otherwise, you could face a disaster if someone charges items you didn't buy to your credit card!
