And a set of stolen or forged plates makes that so much more difficult.
[TELECOM Digest Editor's Note: You are correct on that. In the 'semi- automatic' days of gasoline credit cards (1970's mostly) when the dealer had to manually fill in the gas ticket and imprint your credit card by hand, then you had to sign, Amoco made a point of writing down the license plate number of vehicles. Then, if the owner of the credit card refused payment and claimed his credit card had been stolen, or forged or whatever, clerks at Amoco would look at the microfilm reels of driver's records for the state in particular and look up the name and address of the license plate holder. That particular driver would then get a letter; not exactly threatening, but not exactly friendly, either:"Dear Mr. Jones: On (date) at (time) at (location) a (vehicle make and model) registered to you received a fill up of gas by using a credit card, the owner of which stated to us under oath was stolen/misused/ abused. We would very much appreciate a response from you telling us how you think this may have happened. Sincerely, Amoco Credit Department". Mr. Jones (if he was the purchaser) was in effect put on notice that the collectors did not want to hear any more nonsense about his alleged 'stolen credit card' (if the same Jones was also the card holder). Often times however, Jones would write back to say that his license plates had been stolen. PAT]
