Abstract: A PDA device is used to record the ID of a vehicle boot RFID tag and to transmit to the tag and to a host entity violation data such as summons number, license number, time and date stamp, issuing person ID, location of the vehicle, scofflaw data and so on. This data may be entered into the PDA electronically via a communication network such as the internet or LAN system or manually via a keyboard. The host entity has a data base which is uploaded with this information and has correlation of RFID tag numbers to an unlock combination number for each boot. When the boot is attached to a vehicle this PDA data is transmitted to the host entity whose contact telephone number is attached to the vehicle being booted. The driver contacts the entity to pay the fine and receive in return the unlock combination. The driver thus can release and remove the boot within minutes of returning to the vehicle and can return the boot at his leisure.
