Any mention of the biometric technology is incomplete without face recognition, also known as facial recognition. While this technology has been around since the 1960s, it gained mainstream acceptance only in the last few decades.

According to a recent research, the global market for face recognition is likely to reach $8.5 billion by 2025. The facial recognition technology is widely used in many applications. Here are top 10 ways the facial recognition technology is redefining the way we do things:

1. To enforce law and order

Many forensic experts and law enforcement officers are using facial recognition tools—along with other biometrics—to identify potential criminals and terrorists. This also includes retail store-related crimes such as shoplifting and thefts where facial recognition comes handy in identifying culprits.

2. To unlock your smartphone

Using facial recognition for unlocking a smartphone is no more restricted to Apple iPhones. Many popular smartphone brands such as Huawei and Samsung are using the technology for the user’s convenience. Besides, facial identification is being widely used in popular social media apps such as Instagram and Snapchat. Bringing the technology to the banking sector, some banks are trying to incorporate facial scan authentication for a much secure ATM access process for its customers.

3. For better marketing and advertising

Personalized marketing and targeted advertising are quite popular among marketing and product companies. Facial recognition is driving this trend to the next level. With face recognition tools, it is no more just about understanding user behavior in a particular age group or showing product recommendations to targeted users, but enabling an individual form of advertising. For instance, by embedding tech devices such as cameras and sensors in its stores’ devices, Walgreens is deploying facial recognition to advertise its products according to individual tastes and interests.

4. For finding missing persons or children

A 2018 NCRB study revealed that the number of missing people including children and older people is increasing in India. In countries like ours where there is already a dearth of police officials available per case, the face recognition technology is the only way forward in tracking missing people. The results so far have been impressive. According to media reports, in 2018, Delhi Police were able to identify and find nearly 3,000 missing children within just four days of launching a facial recognition system. Besides tracing missing people, facial recognition tools can be used in finding victims of human trafficking as well.

5. For faster flight boarding

The face recognition technology can remarkably reduce the average boarding time for air travelers. In India, Cochin International Airport is all set to introduce facial scanning for the passengers, ensuring faster boarding process. In a similar use case, British Airways developed self-boarding airport gates to board over 240 travelers in just 10 minutes without any major queues.

6. To enforce border security

Face recognition can be effectively used for coordinating border security across domestic and international borders—such as in the EU countries. This is among the best technologies for stopping frauds related to fake passports or travelers using multiple identities. For example, EU-LISA is developing a cross-border entry-exit system in the EU that can record biometric data of all non-EU passengers including their facial data.

7. To facilitate faster hotel check-ins

It is not just flight boarding that facial recognition technology can help in. It can also facilitate faster check-ins at hotels as well. Despite all the available technologies, hotel check-ins and checkouts are still a manual process and involves long queues. Biometrics such as face recognition can help hotel guests skip the manual check-in process completely. Besides making it a contactless process, it can improve the overall guest experience.

8. For diagnosing diseases

Imagine your doctor diagnosing your disease simply by looking at your face. This is now possible, thanks to facial recognition tools. For instance, automatic detection of Acromegaly disorder is possible using facial photographs. The process was successful in over 95% of the cases. Other conditions that can be diagnosed using facial recognition include Down’s syndrome, Parkinson’s disease and DiGeorge syndrome.

9. For access control to personal devices

In addition to smartphones, facial recognition can also be used for unlocking or access control to other personal devices or apps including social media platforms. In addition, face recognition is being developed to unlock a user’s residence, car and even credit card. For example, Chinese car manufacturer Bryton is experimenting with facial recognition technology that allows drivers to start their cars simply through a face scan.

10. To track attendance

Be it a church or school meeting or any entertainment event, the face recognition technology is now equipped to track attendance and even improve security. I helps in identifying regular (or not so regular) attendees and even people with bad behavior. An example of this case is the Churchix facial recognition tool that can track church congregations across many countries using CCTV cameras.
