Innovations in fingerprint capture devices

摘要

The image capture device plays a key role in fingerprint authentication. In recent years, we have seen remarkable innovations in these devices, which have reduced the size, lowered the price, and improved the performance. These new sensors have paved the way for deployment of fingerprint authentication beyond law enforcement applications to more widespread personal authentication. This paper provides an overview of fingerprint capture devices. Sensor issues and future trends are also discussed.
