About Arculus
Arculus is a cold storage wallet solution developed by CompoSecure, a leader in metal payment card technology. The Arculus Key Card looks like a premium metal credit card but functions as a hardware wallet. It uses NFC technology to communicate with the Arculus mobile app, requiring a physical tap of the card to authorize any transaction.
The device has no batteries, cables, or screens, making it extremely durable and user-friendly. It employs 3-factor authentication (biometric, PIN, and card tap) to secure assets. Arculus is a legitimate and innovative security product for crypto holders who want simplicity without sacrificing safety.
