My finger won't scan. What is the problem?
If you are having problems scanning your finger on the ievo fingerprint reader, there could be a range of reasons for this. For a successful scan, you need:
- to be registered as a user in the system
- to have your fingerprint enrolled
- to scan the correct fingerprint
- to present and scan the fingerprint correctly
Troubleshooting fingerprint scanning
Are you registered?
Ensure that you have been registered as a user and had your fingerprint registered correctly.
Are you using the registered finger?
Ensure you are using the same finger that you registered with. Each finger has to be registered separately on the system, so if you only registered one finger, you have to present that finger for scanning. The most common finger used is the ‘index’ finger, unless advised otherwise.
Keep your finger still while scanning. In order to get the best scan possible, it is vital you keep your finger still while the sensor is scanning. Do not remove your finger until the sensor has finished its scan. The scanning process is indicated by a white light coming from the sensor plate. Once the scan is complete, remove your finger and wait for access.
Have you damaged your fingerprint?
If you have a cut, abrasion or damage on your finger, it could affect fingerprint recognitionas damaged skin may impair a previously recorded image. In this case, please re-register your finger, or register an alternative finger to use until the original is healed. Once healed, you may be required to re-register your fingerprint as scar tissue may be present which can alter your fingerprint.
Are you placing your finger correctly?
Ensure you are placing your finger on the scanner plate correctly: face down and flat.

Is there excessive dirt/debris on your finger?
Although ievo readers can scan through levels of dirt and debris, having a ‘clean’ finger will always increase the effectiveness of any reader. In addition, ensure that you are not pressing too heavily on the reader during a scan. Pressing heavily on the reader can squash your fingerprint, meaning that the key reference points are spread differently from the original scan.
