Can unregistered fingers be accepted?
Every Fingerprint is unique, so the pattern of significant points that are recorded for a registered finger is also unique. However, for practical use, Fingerprint devices are set to accept less than a 100% match of the pattern of registered points. This is to allow for a damaged finger or a finger placed at a different angle or position on the sensor during verification where something less than 100% of the registered points are scanned. Thus, there is some flexibility in use to ensure that authorised people are not frequently rejected.
The typical reduced acceptance level does introduce a small probability, estimated at 1 in 100,000, of an unregistered finger being accepted. However, this risk is probably a lot less than the chance of someone finding, borrowing or stealing your key.
