Cashless car parking is to be rolled out across Northern Ireland after a two-year pilot.
The system allows motorists to pay for public car parking by credit or debit card and extend their stay over the telephone without the need to return to their vehicle.
A trial began in Belfast almost two years ago and was then introduced to Londonderry, Lisburn, Newry and Omagh in January.
"It makes sense to give other towns which have pay-and-display parking the same opportunity to make use of the scheme," he said.
"The scheme provides a viable alternative to coins at parking machines, allowing a credit or debit card payment substitute and it gives people a convenient way to extend their parking stay."
The system has seen more than 130,000 calls since its introduction last year.
"This is a clear indication that motorists have benefited from using the service," Mr Kennedy said.
