Repeatability of Contactless and Contact Fingerprint Capture

A new generation of contactless fingerprint capture devices has recently emerged. These devices provide the ability to capture a fingerprint without making physical contact with the finger. There is anecdotal evidence that the process of capturing a fingerprint by making contact with it also introduces a certain amount of physical distortion to the finger being pressed against the collection medium.

It is hypothesized that because contactless collection devices do not need to make physical contact with the finger bring captured, the resulting collections from contactless devices are expected to have no mechanical deformation introduced to the finger and provide better intraoperability and as well as better consistency between captures from the same device.
