Tips for Improving Fingerprint Verification

Instructions

The Fingerprint Sensor of Ultraloq Smart Lock is an electronic security system that uses fingerprints for biometric authentication to grant the users access to your Ultraloq Smart Lock.

The Fingerprint Sensor of Ultraloq Smart Locks is different from Smartphones, Computers, and other devices due to the unique hardware and algorithm. Please follow the following instructions to register, and don't refer to any other methods. 

 

Common causes of Low-Approval Fingerprint Verification

The following are some circumstances that can increase the chance of fingerprints failure:

1. Frequently washing/disinfecting hands.

2. Activities that require the use of the fingertips include weight-lifting, rock climbing, gardening, or playing guitar.

3. Frequent or regular handling of paper or typing.

4. Exposures to chemicals, such as bleach, chlorine, acetone, antibacterial products.

5. Age: Skin becomes smoother, and ridges become harder to capture with age.

 

Tips for Successful Finger Verification 

Common Tips 

> The finger is clean, and without any callus, it's not peeling or injured.

> Don't tap too quickly or move your finger around while scanning the fingerprint.

> Cover the Fingerprint Sensor completely with some pressure, not too light or rigid.

> We recommend that each user register multiple fingerprints.
