Some of the potential uses of facial recognition software include:

• To prevent voter fraud during elections
• At ATMs instead of a PIN
• As a computer login

Successful deployments include:

• The German Federal Police employs a facial recognition system on a voluntary basis, which allows members to pass through the completely automated border security system in the Frankfurt International Airport.
• The German Federal Criminal Police Office provides facial recognition on mugshot pictures for every German police agency.
• The Australian Customs Service department uses a computerized border processing system known as SmartGate, which includes facial recognition software to compare the passport holder's face with the image in the passport to certify that the correct owner is carrying the passport.
• The U.S. State Department uses a large face recognition system with more than 75 million photographs, which is regularly used to process visas.
• Almost all casinos employ a face recognition system to identify card counters or doubtful personalities in their black list.
