The increase of contactless payment amounts has been implemented in 75% of retail grocery and convenience store outlets nationwide.
Banking and Payments Federation Ireland said the failure to reach 100% in retail grocery is down to one chain - believed to be Tesco - being unable to increase the contactless amount without significant inconvenience and difficulty across its branches.
The increase in the limit will be online at some remaining outlets from Friday.
The head of Payment Schemes with the BPFI, Gill Murphy, told RTÉ News that "critical services" like pharmacies had all competed the increase. She said Boots would be complete in the next couple of weeks.
Gill Murphy said there had been "massive progress" in getting the increase in place so quick.
She said there had been a call from consumers and retailers to make the increase and she said businesses worked well with the BPFI to make it happen.
Yesterday Tesco said that while it had scoped the project thoroughly and looked at every possible way to introduce the change seamlessly, in order to do so, it would have to carry out a manual fix on over 4,600 terminals in 151 shops across the country.
