For example, in the banking and brokerage industries, Japanese Public Key Infrastructure is often used to open accounts, and the effectiveness of its introduction has been recognized. It eliminates the need to copy identity verification documents, fill out and mail application forms, etc., which are required at the time of opening an account.
