The Financial Supervisory Service demanded that Toss submit a plan to improve its system after 2.1 billion won was withdrawn twice due to an automatic transfer error. The Financial Supervisory Service will review the improvement plan submitted by Toss and then consider whether to conduct an on-site inspection.
According to financial authorities on the 4th, the Financial Supervisory Service on the 2nd demanded that Toss draft and submit a system improvement plan related to the duplicate withdrawal error. It is known to have requested measures such as upgrading the internal program used for withdrawals and increasing the number of staff to check the possibility of errors multiple times. The Financial Supervisory Service is also keeping in mind the possibility of conducting an on-site inspection if problems are found during the review process.
From 2:02 p.m. to 2:40 p.m. on the 1st, an error occurred in which the same amount was withdrawn twice from some customer accounts with automatic transfers set up. The error occurred in 21,000 automatic transfers for 15,000 customers, totaling 2.14 billion won. Toss explained that the error was a system error that occurred during the automatic transfer processing and said it advanced all the withdrawn amounts.
Errors are occurring one after another in Toss's core services. In March, after Toss Bank displayed the exchange rate at the 470-won level instead of around 930 won per 100 yen, a surge of exchange transactions took place, resulting in an incident amounting to 27.6 billion won. Last month, at Toss Securities, an error occurred in the mobile trading system in which Kolmar Korea's first-quarter consolidated results were displayed on a separate basis.
A Financial Supervisory Service official said, "For now, we are not considering an on-site inspection, and we have requested system improvements from Toss."
