Abstract: An electronic parking meter (20) is disclosed for unattended supervision and sale of space usage for a lot having a plurality of numbered parking spaces. After parking his vehicle, a customer proceeds to the meter (20) and is sequentially instructed to initially enter his identification data through a key pad (36), then enter coins and/or paper currency in any sequence to purchase space usage, then activate a transaction complete button (46), and then take a printed receipt from a strip printer (48). A computer (52) in the meter (20) computes the length of time purchased from the amount of money entered in accordance with the current rate. A cathode ray tube (34) provides visual verification of the identification data entered, and also displays the amount of money paid, the length of time purchased and expiration time. These totals are cumulatively updated as more money is entered. The printer (48) provides a lot status log in response to coded command for efficient lot inventory.
