If you think any of the parking companies requesting this information are doing this because they are trying to commit identity theft, then I recommend you turn off your computer now. It takes 4 keys for somebody to be able to view that data in our database and nobody has more than 1 key. I can only speak for our company, but the technology we use is something similiar to what they use in the pentagon. Other companies may have it just sitting on a post it note on a wall, but we defintely don't, because my number is in there as well.
I am more worried about when I go into a doctors office and they have me fill out my information on a piece of paper. I could hack into their system in about 3 seconds blindfolded.
