In this April 23, 2018, file photo, the logo for Visa appears above a trading post on the floor of the New York Stock Exchange. Visa says a problem that left people across Europe unable to use their cards was caused by a hardware fault, not a cyberattack. The card payments company says services are back to normal and its systems are working at "full capacity." It says the problem was caused by "a hardware failure within one of our European systems" and wasn't the result of "unauthorized access." 

Visa says a problem that left people across Europe unable to use their cards was caused by a hardware fault, not a cyberattack.

The card payments company says services are back to normal and its systems are working at "full capacity" on Saturday.

It says the problem was caused by "a hardware failure within one of our European systems" and wasn't the result of "unauthorized access."

Consumers in Britain, Ireland and other European countries reported having credit and debit card payments declined on Friday, and many businesses said they couldn't process Visa transactions.

The bank HSBC said Friday that the "industry-wide issue" affected Visa payments, though ATM machines were still working.
