The credit card-sized card has an LCD screen (1) for displaying the parking place code (2), date and time (3) and remaining credits (7). Each parking place or house is assigned its own code, the first two digits for the town, the third and fourth digits for the owner of the parking place or house, and the fifth digit for the parking charge zone. Number keys (8) are provided on the rear side for inputting the parking place code. Input/output contacts (10) are used to transfer data and replenish credits. The card uses an internal clock, database and microprocessor. |
