What's the Fingerprint Sensor of Ultraloq Smart Lock?

A Fingerprint Sensor is a type of electronic security system that uses fingerprints for biometric authentication to grant the users access to your Ultraloq Smart Lock. Fingerprint Sensors of Ultraloq Smart Locks are different from Smartphones, Computers, and other devices due to the unique hardware and algorithm. Please follow the next 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 being rejected:

1. Frequently washing/disinfecting hands.

2. Activities that require the use of the fingertips such as 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 to light or too hard.

> We recommend that each user register multiple fingerprints.

Special Tips

Except for the general tips above, some Ultraloq Smart Locks have different techniques for using the fingerprint sensor due to the unique hardware and software design. Please refer to the instructions below.

Troubleshooting for Failed Fingerprinting

If you have referred the tips above and are still get failure notifications while scanning the fingerprint, please follow the steps below.

Step 1. Power cycle your lock by removing and reinserting one of the batteries. If the battery is low, please replace them with brand new ones.

Step 2. Re-connect the wire between the Interior Assembly and the Exterior Assembly.
