NH Nonghyup Bank became the nation’s first bank to start the blockchain-based services.

Its app enables customers to get a notification on bills covering national and national taxes, fines, apartment utility bills, credit cards, and insurance premium.

Once customers get a notification, they can immediately pay the bills.

The services replace the current email, fax and Web page notification.

The app uses main features of blockchain technology, making it transparent and free from forgery, a Nonghyup spokesman said Wednesday.

The bank would file a patent application for the services.
