Systems and methods for pairing for-hire vehicles with their associated medallion are disclosed. Some for-hire vehicles, such as taxis operate with a for-hire vehicle meter (taximeter). In some embodiments, the meter contains an identifier of a medallion that is associated with the meter. The meter may then determine if it is connected or properly associated with the medallion. If the meter is connected or properly associated with the medallion, it will then access the identification information of the medallion and determine if identification information matches its contained medallion identifier. If the identification information does not match, the meter may shut down and thereafter be non-engageable. The relationship between the medallion and the meter is advantageously used to enforce restrictions on the operation of the for-hire vehicle including, for example, time and location of pick-up restrictions. In other embodiments, meters and medallions communicate their identification and locations to a central server. The central server then compares the locations to determine the distance between the meter and the medallion. If the distance does not satisfy a predetermined range (indicating the meter and the medallion are close together), the central server may generate an alert or it may command the meter to shut down. The central server may also advantageously be used to enforce restrictions on the operation of the for-hire vehicle. Meters and/or medallions not attached to their assigned medallion and/or meter may also be tracked via the central server.
