21 Amazing Uses for Face Recognition – Facial Recognition Use Cases

Since the 1960s, face recognition has appeared in one form or another, but recent technological developments have led to the widespread popularity of this technology. This technology is no longer regarded as something like the science fiction movie "Minority Report". With the release of iPhone X, millions of people have now mastered facial recognition technology that can protect their data and personal information. Although mobile phone access control may be the most recognizable way to use facial recognition, it has been widely used in a variety of use cases, including crime prevention, incident protection, and making air travel more convenient.
We have compiled 21 current methods of using facial recognition to make the whole world safer, smarter and more convenient.

Prevent retail crime

Currently, facial recognition technology can be used to immediately identify when known shoplifters, organized retail criminals, or people with a history of fraud enter retail premises. Personal photos can be matched with a large database of criminals so that when shoppers enter the store to prevent threats, loss prevention and retail security professionals can be notified immediately. The face recognition system has radically reduced retail crime. According to our data, facial recognition can reduce external shrinkage by 34%, and more importantly, it can reduce violence in retail stores by up to 91%.

Unlock phone

Various mobile phones, including the latest iPhone, now use facial recognition to unlock the phone. This technology is an effective way to protect personal data and ensure that even after the phone is stolen, criminals still cannot access sensitive data.

Wise advertising

Facial recognition can make advertisements more targeted by making educated guesses about people’s age and gender. Companies like Tesco are already planning to install screens with built-in facial recognition at gas stations. It is only a matter of time before face recognition becomes a versatile advertising technology.

Search for missing persons

Facial recognition can help us find missing children and those who have been trafficked by human traffickers. As long as the missing persons are added to the database, they can immediately identify law enforcement officers through facial recognition (whether it is an airport, retail store or other public place) and alert them. In fact, 3000 missing children were found in India in just four days!

Help the blind

Listerine has developed a breakthrough facial recognition application that can use facial recognition to help blind people. The app can recognize when people smile and alert blind people through vibration. This can help them better understand social situations.

Protect law enforcement

Like the one provided by FaceFirst, mobile facial recognition apps have helped police officers by helping them identify people on the spot from a safe distance. This can help them by providing them with contextual data, telling them who they are dealing with and whether they need to be cautious. For example, if a police officer pulls down a wanted murderer at a routine traffic stop, the police officer will immediately know that the suspect may be armed and dangerous, and can request reinforcement.

Auxiliary forensic investigation

Facial recognition can automatically identify individuals in security videos or other videos, thereby helping forensic investigations. Face recognition software can also be used to identify dead or unconscious people at the crime scene.

Identify people on social media platforms

The Facebook team uses facial recognition technology, which can automatically recognize when and where Facebook members appear in the photos. This makes it easier for people to find the photo they are in and can suggest when to tag specific people in the photo.

Diagnose the disease

In addition to judging facial attendance, face recognition can also be used for medical diagnosis, and can detect changes in diseases based on changes in facial appearance. For example, the National Human Genome Institute Research uses facial recognition technology to detect a rare disease called DiGeorge syndrome, in which part of the 22nd chromosome is missing. Facial recognition helps diagnose the disease in 96% of cases. As algorithms become more complex, facial recognition will become a valuable diagnostic tool for various situations.

Identify VIPs in sports games

Face recognition can bring more good user experience to fans. When season ticket holders participate in sports events, facial recognition can be instantly recognized. Event venues can provide them with stolen goods, allowing them to skip the line and other VIP privileges, thereby increasing the season for ticket holders.

Protect the school from threats

The face recognition monitoring system can immediately identify when deported students, dangerous parents, drug dealers or others who pose a threat to school safety enter the campus. By reminding school security guards in real time, facial recognition can reduce the risk of violence.

Orbital school attendance rate

In addition to making schools safer, face recognition can also track student attendance. Traditionally, the attendance sheet allows students to sign in to another student who is leaving the class. But China is already using facial recognition to ensure that students will not skip class. Tablets are being used to scan students’ faces and match their photos with databases to verify their identity.


Face recognition can help the casino identify the moment a cheater or dominant gambler enters the casino. In addition, the face recognition function can also identify members on the voluntary exclusion list. If they are gambled, they may have to pay huge fines to the casino.

Stop toilet paper thief

In China, the theft of toilet paper from public toilets is a big problem. Fortunately, face recognition can be solved. China has installed machines in public toilets that can scan people’s faces before releasing toilet paper. It will not release more paper to the same person until 9 minutes have passed.

Promote safe transactions

In China, there is a financial services company called Ant Financial that allows customers to scan their faces to pay for meals. Customers place an order through a digital menu and then use facial scanning as a payment option. After providing their phone number, they can purchase meals.

Verify identity in ATMS

Since facial recognition is a powerful identity authentication tool, it seems that facial scanning will eventually completely replace ATM cards. But at the same time, facial recognition can be used to ensure that the person using the ATM card is what they say is their true identity. Macau's ATMs are currently using facial recognition technology to protect people's identities.

Make air travel more convenient

Airlines have begun to use facial recognition to help people check their luggage and board and board more quickly. It seems that we are rapidly moving towards a future in which air travel is not only safer than ever before, but also more convenient than any period in history.

Church attendance

The church has begun to use facial recognition to see who is showing up in its congregation. This can help them determine who to ask for donations and which members to contact to get them to participate more often.

Find lost pets

Finding Wanderers is an application designed to help owners reunite with their lost pets. The app uses face recognition (an animal's face in this case) to match photos uploaded by pet owners with a photo database of pets in shelters. The app can then immediately warn the owner if they have found their pet.

Identify the driver

More and more car companies are trying to use facial recognition methods. One use of facial recognition in cars is to use faces instead of keys as a means of starting a car. Face recognition can also be used to change radio station and seat preferences based on who is driving. Facial recognition can even make drivers safer by identifying and warning them if they are drifting or not on the road.

Controlled access to sensitive areas

Face recognition can be used as a means of access control to ensure that only authorized personnel can enter facilities such as laboratories, board meeting rooms, bank vaults, athlete training centers, and other sensitive locations.
