Facebook has been in the process of developing a facial recognition tool linked to cameras in high end shops which will allow the staff to improve their customer service by gaining insight into customer’s user profile, it has been reported.

Facebook reportedly has applied for a patent for a technology that will gauge customer's emotions and brand choice by leveraging their Facebook profiles through crowd-scanning technology.

As reported by The Times, Facebook, in its patent application, has mentioned that it wants to provide improved customer service to visiting customers of a brick-and-mortar merchant location.

Facebook is further working on facial recognition to allow payment at shop tills.
