Welcome Savings Bank Implements Blockchain-based Bank ID for Enhanced Customer Convenience
Welcome Savings Bank, one of the mutual savings banks in South Korea, has announced a significant step towards enhancing identity security and customer convenience with the incorporation of Bank ID, a blockchain-based decentralized identity (DID) solution operated by the Korea Financial Telecommunications and Clearings Institute (KFTC), a payment services institution.

DID technology to prevent identity fraud
The utilization of DID technology marks a notable stride in preventing identity fraud. By storing user data on a secure distributed ledger, the system becomes highly resilient to counterfeiting or forgery attempts, ensuring a safer environment for customers’ personal information.

With this initiative, Welcome Savings Bank has become the first savings bank in the country to implement Bank ID, a solution predominantly adopted by prime commercial banks. This strategic move bolsters the bank’s digital competitiveness and improves customer convenience. With Bank ID, users can enjoy seamless access to their accounts across 18 Korean financial institutions without the hassle of logging in separately for each one, streamlining their banking experience.
Customers of Welcome Savings Bank can utilize the bank’s mobile app to acquire a Bank ID by undergoing a verification process through a one-time password or security card. For existing Bank ID holders, adding Welcome Savings Bank to their list of banks is a straightforward procedure.
The decision to embrace this innovative technology highlights the bank’s commitment to meeting the high standards set by prime commercial banks. By aligning with industry trends and bolstering their digital capabilities, savings banks like Welcome and other subprime banks can deliver improved convenience and a seamless banking journey to their valued customers.
