The Details

The Challenge: Security that Doesn’t Compromise Usability

Many online payments services rely on password-based logins, which are the most insecure of authentication methods. Passwords have been cited as the root cause for the vast majority of data breaches in recent years and are often frustrating for consumers because they can be complex and hard-to-remember.

With the rise in biometric authentication services, consumers are coming to realize the convenience of using this method for easy login. Recognizing the opportunity to leverage existing smartphone features such as cameras, BC Card set forward to integrate biometrics into the paybooc application.

The Solution

BC Card wanted to find a better way to authenticate paybooc users for an easier and more secure payment experience. After considering a number of authentication methods, the company launched FIDO-based fingerprint, voice and facial biometric authentication methods for paybooc users.

paybooc was the first system among Korean financial institutions to provide FIDO® Certified voice and facial recognition.

The FIDO-based voice authentication system is built to identify distinct features of the user’s voice, and is able to distinguish between a recording and an authentic voice. The FIDO-based facial authentication system recognizes the user’s facial features through the mobile device camera. Both systems utilize on-device cryptographic credentials and biometric data to protect from remote spoof and other attacks (i.e. the use of sounds, pictures and videos to mimic the user).

Verifying customers has become an important issue for the mobile payments industry, and biometric capabilities are rapidly evolving to create a safer and more reliable service for users. BC Card chose FIDO Authentication as a way for consumers to have secure logins with the ease of standards-based, interoperable authentication utilizing biometrics.

The Result: 1.2 Million Registered Users, 1 Million Monthly Transactions

As of May 2018, over 1.2 million users have registered in paybooc using biometric authentication, making over 1 million transactions monthly. This number is on a steady increase, as users recognize the ease of using biometrics as authentication as well as the extra security FIDO standards provide users. In the payments industry, mobile transactions are on the rise, and paybooc’s FIDO biometric authentication can adapt to any device.


BC Card’s decision to adopt the FIDO standard for authentication with biometrics was prompted by a need for stronger authentication for its mobile payments services, but also a seamless user experience. FIDO provides interoperability, ensuring that users can be authenticated on a wide array of device choices regardless of mobile carrier, device maker or online service. FIDO Authentication is a fast and convenient alternative to solutions like passwords, which are often difficult to remember, because it requires only a single gesture to log on.

BC Card also chose FIDO as a safeguard against fraud. Spoofing, phishing and other attacks are a direct concern for any payments service looking to best authenticate users. The FIDO protocols use of on-device cryptographic credentials and biometric data cut out third-party and man-in-the-middle involvement and significantly reduce the chance for hacks or phishing.

This assurance, along with the standards-based architectures that can evolve, scale and change with the market make FIDO Authentication a secure, cost-effective, and simple choice for BC Card paybooc. Many biometric authentication services, including Samsung Pay, are FIDO-based, and the quickly spreading FIDO2 standard is well-known throughout Korea.
