In India, a bunch of financial services apps, from ICICI to Paytm Money and HDFC Bank, have started using face recognition, negating the need to enter a PIN for transactions
Over the years, companies have offered everything from number locks to patterns and even fingerprint scanners to protect phones, and for authentication in place of passwords or to initiate payments.
Of late, there has been a move towards the phone recognising user’s face and then opening the screens for her. Samsung has, for instance, experimented with iris scanners, and has settled with face unlock, where the phone matches ‘face’ to what it has in its records. A lot of other Android phones, too, use face unlock in one way or the other. Apple, meanwhile, has been using Face ID, which is more complex than face unlock on Android phones, as it uses more layers of data.
