Unique approach combines multiple sensing methods to prevent identity fraud

New York, NY — May 6, 2026SLC Digital, a pioneer in SIM-based identity authentication and fraud prevention, today announced that it has secured a new patent for an advanced biometric authentication system that uses a graphene-based sensor to verify identity more securely.

Today's biometric systems, such as fingerprints or facial recognition, typically rely on a single signal. That makes them increasingly vulnerable to spoofing, especially as AI tools make it easier to replicate voices, faces, and other identity markers.

SLC Digital's patented system takes a different approach. Instead of relying on a single type of biometric input, the technology combines three sensing methods—optical, ultrasound, and electrical signals—into a unified graphene-based surface. This enables the system to capture both surface-level and deeper biological features, creating a more complete and significantly harder-to-fake identity profile.

"This new patent represents a significant step forward in biometric authentication," said Travis McGregor, CEO of SLC Digital. "By combining multiple sensing modalities in a single hardware-based system, we can move beyond surface-level biometrics toward a deeper, more secure form of identity verification."

The technology is designed to operate in a compact, smartcard-sized device, enabling secure, portable identity verification. As part of a broader hardware-rooted identity architecture, it anchors trust in tamper-resistant devices rather than easily manipulated digital signals—helping organizations verify that a real, authorized individual is physically present during sensitive transactions.

The patent reflects SLC Digital's continued investment in hardware-rooted identity technologies designed to address the growing limitations of traditional authentication methods in an era of AI-driven fraud and digital impersonation.

SLC Digital was awarded the issuance of United States Patent No. US20250307373A1 - System and method for human authentication using graphene membrane for unobstructed optical, ultrasound, and capacitance sensory and communication in distributed computing card format.

About SLC Digital

SLC Digital is an identity authentication company that helps organizations prevent account takeover and high-risk digital fraud, through the most secure communication channel available for digital authentication. Identity is verified through the SIM/eSIM and mobile network, establishing hardware-based, cryptographic proof that the real, authorized device is present and trusted—ensuring that only legitimate users can perform sensitive actions. The company works with global partners including GSMA, IDEMIA and Monogoto to deliver secure, network-native digital trust at scale, and is a member of the NVIDIA Inception program, which supports startups advancing AI-driven technologies.
