Abstract

A parking data transfer system has first and second communications devices. The first communications devices each include a timing device, a first display for displaying a parking time and first transmitter for transmitting a notification when the time measured by the timing device has reached the parking time. The second communications devices each include a notifying device for notifying receipt of the notification transmitted by the first transmitter. The first communications device modifies the parking time on receipt of an updating signal transmitted by the second communications device.
