There are three main types of fingerprint sensors: capacitive, optical and ultrasonic.
Each of these sensors operates slightly differently depending upon the material and collection methods used in the mould.
Reaching this success rate was difficult and tedious work.
The results show fingerprints are good enough to protect the average persons privacy if they lose their phone.
The researchers used a 3D printer to create molds and cured them in a UV chamber.
To start the testing process, the researchers used infamous gangster Al Capones publicly available fingerprints as an example.
Mobile devices proved to be the best targets, as most people commonly use fingerprint sensors on their devices.
For a regular user of fingerprint authentication, the advantages are obvious, and it should be used.
