ABSTRACT:
An automatic system and method using prepaid cards for collection of the expressway tolls while the vehicle is moving at a normal driving speed where a computer-network is not required. Upon insertion of a valid prepaid card with a sufficient cash balance to pay the maximum toll for an expressway into a card reader/writer of an in-vehicle device, the device is turned `ON`. A transmitter in the device is actuated to continuously transmit an infrared signal to cancel the activation of an alarm at the toll facility and to activate a transmitter of the toll facility to transmit an infrared signal of a predetermined modulation frequency identifying each toll facility. A data processing means of the in-vehicle device calculates toll using information from the infrared signals received one at the entrance and another at the exit and reduces toll from the cash balance in the prepaid card. The card reader/writer rewrites the resulting amount onto the card. When the cash balance is less than the maximum toll, upon insertion of the card in the in-vehicle device an alarm is actuated to notify the driver. The prepaid card used can be a magnetic card. When the driver insists to pass through the automatic toll collecting booth without proper means for paying toll, an alarm at the toll facility is actuated together with a camera to take the picture of the license plate of the invader's car.
