Until today, there existed such Fingerprint Biometric Readers that required your touch to authenticate yourself as an authorized person. However, the latest research shows that the future of fingerprint scanners lies in a "no-touch" activity by an individual for gaining access. Recently, NIST (National Institute of Standards and Technology) has funded a number of startup and companies to develop touchless Fingerprint readers.
The Contactless Biometric Technology requires the person’s presence, but from meters away. As the fingerprint scanners can sense and read your fingerprint information while you are standing few meters away from the scanner.
