How biometrics protect your credit cards Automatic translate

Banks that issue credit cards using modern biometric authentication technologies ensure reliable protection of personal data when paying for online purchases. Financial institutions are implementing facial recognition and fingerprint authentication for transaction confirmation. Customers gain an additional level of security without having to enter passwords.

What is biometric security in banks?

Biometrics uses a person’s unique physical characteristics for identification. Banks use facial scanning, fingerprints, and voice recognition. The unified biometric system stores data in encrypted form. The Central Bank of the Russian Federation regulates personal information processing standards. This technology replaces SMS codes and one-time passwords.

Access to a credit card requires confirmation via a smartphone equipped with a biometric sensor. Fraudsters will be unable to use the stolen data without the owner’s physical presence.

How does face and fingerprint authentication work?

Facial recognition analyzes facial features using the front-facing camera. Algorithms compare the image with a reference image in the Unified Biometric System (UBS) database. The fingerprint is scanned and converted into a digital template. Banks do not store the original biometric data, only hashes.

Two-factor authentication combines biometrics with a password or PIN. Credit cards with this type of protection are resistant to phishing and social engineering. Two-factor authentication does not affect access to biometric features.

Advantages of biometrics over traditional methods

Security is enhanced by the uniqueness of biometric parameters. Convenience means there’s no need to remember complex passwords. Transaction confirmation is reduced to 2-3 seconds. The National Bureau of Credit Histories (NBCH) notes a reduction in the number of fraudulent transactions with biometrically protected cards.

Missed SMS confirmation codes don’t affect your credit rating. Customers are less likely to block their cards by mistake.

Risks and limitations of biometric technologies

Data privacy requires strict control. Leakage of biometric templates is irreversible — a fingerprint cannot be changed like a password. Banks are required to comply with Federal Law No. 152 on personal data. False positives are possible in poor lighting or if a finger is injured.

Tip: Set up a backup login method — password or SMS — in case biometrics fail.

Which banks have already implemented biometrics?

Sberbank, T-Bank, VTB, and Alfa-Bank offer face or fingerprint login in their mobile apps. Credit cards with biometric security can be selected through online services. OKB has seen a 35% year-over-year increase in the share of cards with this feature.

Recommended: Check the security settings in your bank’s app and enable biometrics if supported.

How to set up biometric security on a card

Open the bank’s mobile app. Go to "Security" or "Login Settings." Select your authentication method: face or fingerprint. Follow the instructions for scanning. Confirm activation with a code sent via SMS.

Please note: Biometrics only works on devices that support the feature — check your smartphone’s compatibility before setting it up.

Technology is changing financial security standards. Biometrics makes using credit cards more convenient and secure. Manage your access settings and update your app regularly. Adapting to new security methods reduces the risk of fraud.
