FACE RECOGNITION SYSTEM

Means

A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database.
It is typically used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. SOURCE

For better understanding if you are one of the users of social networking site Facebook, Facebook uses this type of technology is called "Photo tagging".

Facebook Purpose:

"people can use facial recognition to help them easily identify a friend in a photo and share that content with them. This is the same feature that millions of people previously used to help them quickly share billions of photos with friends and family."

As we announced last year, we temporarily suspended our photo tag suggestion feature to make some technical improvements. Today, we're re-enabling the feature in the United States so that people can use facial recognition to help them easily identify a friend in a photo and share that content with them. This is the same feature that millions of people previously used to help them quickly share billions of photos with friends and family.

How Does it works Facial Recognition System in the Next-Generation

Uniqul system installs facial recognition cameras to checkouts in shops
A customer nods at the camera and the software scans their face
This is compared to a database of stored faces and linked payment details
The shopper confirms the transaction using a touchscreen display

Bank cards are already being replaced by phones and wristbands that have payment technology built-in but the latest threat to the lowly plastic in your pocket could be your face. A Finnish startup called Uniqul has launched what it calls the first ever payment platform based on facial recognition. The system doesn’t require a wallet, bank card or phone - instead a camera is positioned at the checkout and takes a photo of a shopper's face when they are ready to pay. It then scans a database for the face and matches it to stored payment details in order to complete the transaction.

cash machines set

The Diebold Millennial ATM uses facial recognition instead of bank cards
Unique one-time security codes are sent to the phone by text message
The user then enters this code to withdraw their money
It is just one of the concepts recently showcased at a London conference

Ohio-based security firm Diebold has created a touchscreen cash machine that works like a tablet computer, uses facial recognition and QR codes to identify and authenticate users, and has built-in safety cameras. While German-based engineers at Wincor Nixdorf have developed a machine that remembers the user's withdrawal history to offer more personalised options.
