# SLC Digital

> SLC Digital provides identity authentication technology through a dedicated channel between enterprises and their customers' devices. Using the SIM/eSIM and mobile network, SLC delivers hardware-rooted, cryptographic proof of identity and intent — eliminating reliance on passwords, OTPs, and app-based authentication that can be phished, forwarded, or socially engineered.

SLC Digital is headquartered in Albany, New York. The company's technology leverages the SIM card's secure element and mobile network infrastructure to establish an out-of-band authentication channel that operates independently of the public internet, phone numbers, and software layers. This approach shifts identity authentication from probabilistic, software-based signals to deterministic, hardware-rooted proof.

Key differentiators: app-less and OTP-less authentication, no phone number dependency, silent SIM applet provisioning, cryptographic proof of both identity and intent, and global coverage through mobile network operator partnerships.

SLC Digital is a member of the GSMA and NVIDIA Inception program, and partners with organizations including Monogoto and IDEMIA.
