Biometric Security, 
Built for Privacy

The Nymi Band processes your fingerprint image during enrollment. It translates the image into a mathematical template, and then discards the fingerprint image (these are never stored).

Securely in protected memory within the Nymi Band, where it remains until deleted. It is not accessible from outside the device.

Until you delete it, which can be done at any time; simply place the Nymi Band on a charger, tap twice on the fingerprint sensor, and once you see the "Delete User Data" screen, press and hold your finger on the sensor until completed. Just know you will have to re-enroll your Nymi Band after a reset.

Your fingerprint template can’t be accessed by your employer or anyone else, and you can delete it anytime using the Nymi Band’s security wipe feature.

Yes—any time you link your Nymi Band to an account it may store information like your username. Passwords are not stored on the Nymi Band.

No.

Traditional biometric solutions require enrolling on multiple devices and often store data centrally, posing security risks. They also struggle with PPE. The Nymi Band stores biometrics securely on the band itself, enabling authentication across shared devices without central storage or re-enrollment—and it works with PPE.

Centralized PII storage increases cybersecurity risks as they are attractive targets. It removes user ownership and control of that data, and often requires data replication, which amplifies exposure (similar to the vulnerabilities of duplicating private keys in cryptographic systems).

With any solution, consider how many copies of your biometrics are made, where they are all stored, and how/if you have the ability to delete all copies at will.

The Nymi Band makes one copy of your biometrics (as a mathematical template) and it’s securely protected in your band where you can delete it forever at any time with a simple 10-second reset.
