The new eParking system in Monaghan town was used just over 2,600 times last month.
This represents around five per cent of all parking in June.
However, Monaghan County Council expects this to rise to 40 per cent over the coming months.
Cashless parking in the town was first proposed last September, when Monaghan County Council announced it issued a tender for a new parking system.
The phone app and website for cashless parking was introduced in April and trialed through May without any promotion or advertising.
In May, the system was used 450 times, and that increased to 2,621 with promotion in June.
That equals close to five per cent of the estimated 52,000 parking transactions in the town for the month.
The council says "it is very early days in terms of usage of the system" and they expect this to rise to 40 per cent in the long term.
Separate to this, and in an effort to improve the cash pay parking system, Monaghan County Council is in the process of installing new machines at existing locations across the town.
