Visa card services are back to normal said the company after hardware failure prevented people all over Europe to use their cards for payments.
It also apologised and said Friday's disruption was not associated with "any unauthorised access or cyberattack".
"Visa Europe’s payment system is now operating at full capacity, and Visa account holders can now use Visa for any of their purchases and at ATMs, as they normally would," said a statement by the company.
Payments made with Visa cards suddenly stopped working on Friday across Europe, including the UK. The problem appears to have started at around 2:30 p.m.
Banks and shops in the UK took to Twitter to alert customers about the disruption.
Angry customers stuck in queues for ATMs, also took to social media to vent about their cards not working.
A British traveller in Sicily said he was left stranded in Palermo because his Visa card didn't work.
Five hours after detecting the problem, Visa said the system was working "close to normal" and apologised for the trouble caused by the disruption.
