Payzone has won the contract to provide BetEire Flow with online toll payment services for the M50
Payzone has the contract for five years with an option to extend it for a further three years.
Drivers are expected to have the option to pay M50 tolls via the internet, mobile phone or at one of 2,000 shops that stock Payzone mobile phone credit.
Payzone was formed after the merger of electronic payments firm Alphyra and British cash machine operator Cardpoint.
