ING Bank Romania shut down its whole electronic payment processing system on Saturday afternoon, due to technical problems, the bank announced, Romania-Insider informs.

More than one million people who have cards issued by ING have been affected as they couldn’t withdraw cash from the ATM or use their cards for shopping, and the problem was still not solved late on Saturday evening.

Moreover, ING clients couldn’t even use the Home’Bank system for online payments or to check their balance. The system was back online around 22:00.

The retailers who have card acceptance terminals from ING haven’t been able to use them either. Thus, some retailers who have exclusive contracts with ING, haven’t been able to serve clients who wanted to pay by card and could only process cash purchases. Such has been the case of Lidl, one of the top supermarket chains in Romania.

ING Bank is one of the top local banks in terms of card payments. At the end of last year, the bank had over 1.2 million cards issued, some 1.1 million of which were used by individuals and close to 100,000 were company cards.
