Barrier Free: M50
The M50 motorway around Dublin does not have a plaza. The eFlow Barrier-Free toll system between Junction 6 and Junction 7 records trips by photographing a vehicle's licence plate number. Drivers without an electronic toll tag or eFlow video account must pay for their journey before 8pm the following day to avoid late payment penalties. Payment options include:
 Online at www.eflow.ie
 Calling 0818 50 10 50 / +353 1 461 0122 to pay by card
 Paying in any Payzone branded outlets nationwide
 Registered customers can use their electronic toll tag or eFlow video account

Most major Irish car rental companies (e.g., Enterprise, Budget, Europcar, Sixt) provide an automated M50 toll tag system, often called EXPRESSTOLL. This allows you to drive through the barrier-free M50 tolling point, with fees (approx. €3.80 per trip + service fee) charged directly to your credit card, avoiding hefty fines. [1, 2, 3, 4, 5]
