This information can then be used without the person's consent, leading to a person's bank information, or even worse information being stolen, and used against that person.
Getting this information may not be as hard as one would think. And once the thief has it, their next few steps are relatively simple. Before you know it someone else out there could be overcharging credit cards, applying for loans, and even committing other crimes, all using something that doesn't belong to them: Your name!
The internet is not the only place people can find information about you either. Some people think that identity theft can only happen if they loose their wallet for example, but this also is not true. The list of places people could find this information is almost endless; "your doctor, accountant, lawyer, dentist, school, place of work, health insurance carrier, and many others have your identifying information. If some criminally minded person is working at the office (or just visiting) decides to use this information to assume your identity, you would not know it. Also if this information is not disposed of with a shredder, a "dumpster-diver" could pick up the information and begin the crime against you. You do not need to lose your wallet or have anything tangible stolen from you for someone to take your identity.
