ATM card users were unable to withdraw money under the cross-banking system on Monday afternoon due to IT technical errors, resulting in payday chaos.
Call centres of commercial banks were flooded with complaints from customers that they could not withdraw money by using the ATM machines of other banks, which normally can be done without a problem. As Monday was the last day of the month, payday for many people, the number of ATM users increased two or three fold over average daily use.
Weidt Nuchcharoen, senior executive vice president of Krungthai Bank, said the investigation found the problem arose from a system error at National ITMX Co, which is the system provider for the intra-bank clearing system, causing the break down of the ATM pool.
