Frontline worker authentication: Crayonic vs OLOID vs Nymi
OLOID, Nymi and Crayonic all try to make authentication disappear for frontline staff, in different ways. OLOID uses “AI-powered computer vision” to check the user stays present (OLOID). Nymi Band 3.0 is a FIDO2-certified wristband with “continuous biometric authentication” over NFC (press release). The Crayonic Badge is a FIDO2 security-first wearable that signs workers in by presence.

How to choose
If every device already has a camera and staff can be seen clearly, camera presence is low-touch. If you want a wearable credential that never relies on a camera, compare the Nymi Band and the Crayonic Badge on form factor, how login happens at the workstation, and what else the device must do on your floor. How continuous authentication works with the Badge.

Frequently asked questions
What is the best authentication for frontline workers on shared devices?
One that is phishing-resistant, takes seconds, locks on walk-away and needs no personal phone. Camera presence, biometric wristbands and badge wearables each meet some of these; the Crayonic Badge combines FIDO2 credentials with presence-based login and logout.
Does the Crayonic Badge use a camera?
No. Presence comes from the Badge itself and a Crayonic Bridge at the workstation.
Is the Crayonic Badge FIDO2 certified?
Yes, FIDO2 Level 1, with Level 2 certification expected in H1 2027.
