No card, phone, or cash needed! This tech lets you pay with just your face

Cash, cards, and mobiles might soon be history. This new technology lets you pay using facial recognition. Private lender Federal Bank has rolled out SmilePay, a facial authentication technology that allows customers to make payments using just their facial recognition. The system, introduced at the Global Fintech Fest, is the first of its kind in India, and it operates on the government-backed BHIM Aadhaar Pay infrastructure.
