Abstract:

The customer starts a parking experience by entering an identifier, such as a phone number or thumb print, using a Flow Thru Box to record the individual and the time they entered, combined with the capture of his/her License Plate information to identity the vehicle. The vehicle identity and the customer identity are then joined (such as identifier and time). This information is stored in a server for retrieval when customers wish to calculate their time for payment. The customer arrives at a Flow Thru Box and enters their information so the Flow Thru software can find their parking record stored on the server. That information is used to calculate the time parked and the associated fee. When the customer exits the facility in their vehicle the License Plate camera records the vehicle License Plate information and checks the server to determine if the driver of the vehicle has paid.
