Enable payment cards as an authenticator
Better multi-factor security, with card-based authentication
Digital banking has transformed how customers interact with financial services. But as digital convenience has increased, so have security threats. Traditional single-factor authentication – relying on usernames and passwords – is no longer sufficient in a world of phishing, credential theft, and sophisticated cyberattacks.
To truly protect customers, financial institutions need authentication that is both stronger and simpler. A solution that enhances security without adding friction. One that fits naturally into users’ everyday lives while elevating the digital experience.
The answer may already be in their wallet.
Payment cards: the natural authentication device
Payment cards are already engineered for secure transactions. They are cryptographically protected, globally standardized, and universally trusted. Most importantly, they are always with the user. This makes them uniquely positioned to act as powerful multi-factor authentication devices in the digital world.
G+D enables issuers to integrate authentication capabilities directly into their payment programs –transforming physical cards into secure digital access credentials for banking apps, transaction approvals, onboarding, and beyond.

The better way to authorize logins and payments
By making your payment cards authentication devices, you can unlock a whole host of capabilities and optimizations – while keeping both your card and your account details secure.

Many implementation options for authentication
There are a number of methods to provide added security to cardholders, from two-factor authentication to multi-factor authentication using card bodies as authenticators.
FIDO2 Pass Keys
Designed to be frictionless, pass keys improve sign-in success by linking app logins to device authentication (such as through PIN, pattern, or biometrics).
- Global browser support
- High phishing resistance
- Requires new applet

Proprietary NFC Data Exchange Format (NDEF) solution developed by G+D
Secure communication between NFC-capable devices (like mobile phones) with NFC cards for authentication. This solution requires cards to be reissued, but offers an improved customer journey.
- Custom use-cases for smoother customer experiences
- Proprietary app/server required
- Data delivery and other actions activated by card tap to phone

EMV®-native authentication
Turn existing payment cards into authentication devices without the need for a new applet.
