Biometrics backed mobile payment service Samsung Pay has launched in India.Samsung phones like the Galaxy S6 and Galaxy S6 Edge alongside the upcoming Galaxy S8 and Galaxy S8+ are also expected to be compatible with the service.The payment service will be launched on Visa, Mastercard and Rupay payment cards. ICICI, HDFC, Standard Chartered, SBI, Axis bank cards will be supported, along with Paytm and Amex cards.Nearly 90% of all POS machines in India work on magnetic technology for payments with cards. The Samsung Pay service uses a similar technology. The service creates a magnetic field between the POS machine and the phone to replicate a card transaction.There has been no word on whether there could be any link up between Samsung Pay and the Indian government's own planned biometric mobile payment system, Aadhaar Pay.
