This document summarizes PARKTxT, a text service that allows car park customers to check how much time and money they have spent parking. It provides updates on tariff changes and targeted offers from local businesses. The 6-member team plans to launch the service in Belfast in May 2010 through partnerships with major car park operators. They forecast revenue growth over 3 years based on conservative estimates of 20% customer usage from the 1000 parking spaces at two launch sites.
