Mizuho Bank said Friday that it will suspend work to transfer data for digital accounts for the foreseeable future, following a recent system glitch that caused an outage at most of its ATMs in Japan.
The move is designed to focus on identifying the cause of the glitch and preventing any recurrence.
In January, the Mizuho Financial Group Inc. unit began to charge fees for paper passbooks for customers who newly open accounts and launched a digital account service allowing users to check their transactions online.
Since late last month, the bank has been working to transfer into digital accounts the data on accounts for which no record of transactions appears on passbooks for at least one year.
But about 80% of the bank’s ATMs became unavailable temporarily on Feb. 28, when the data transferring work placed an excessive burden on the bank’s computer system.
ATM users whose cash cards or passbooks were swallowed by such machines were forced to wait a long time for help. On Wednesday, another system glitch hit the bank’s computer system.
