> One Tap Total Security

Arculus is a digital asset custody and authentication company. It provides a tap-to-transact hardware card and mobile app for cold storage of cryptocurrency and NFTs, plus passwordless authentication for businesses.

Arculus is a digital security company that provides cold storage and authentication hardware for digital assets. Its core product pairs a metal tap card containing a secure hardware element with a mobile app, letting individuals store cryptocurrency and NFTs offline while keeping private keys isolated from internet-connected devices. The offering is built around three factor authentication, combining a physical card, a personal PIN, and device biometrics to approve transactions.

The platform addresses the risk of software-only wallets and password-based logins by requiring a physical tap between card and phone over a short-range wireless connection before any transaction or authentication event can proceed. Private keys are generated and stored on the card itself and are never exposed to the connected app or device. Users can connect their wallet to decentralized applications and marketplaces to manage, swap, and transact with their holdings.

Beyond self-custody storage, Arculus offers authentication and payment solutions aimed at banks, fintechs, exchanges, and gaming platforms seeking to reduce fraud and password reliance. Its product lines span cold storage wallets, passwordless login and high-value transaction approval tools, and card-based authentication for loyalty and payment use cases. Arculus is used by individual holders of digital assets as well as businesses in banking, fintech, gaming, and cryptocurrency exchange sectors.

Businesses deploy it to reduce fraud, false declines, and call center burden while giving end users a hardware-backed login and approval method. (Service Provider, Live)
