When you go to pay for that cup of coffee at your favorite coffee shop you have a variety of ways to pay which also include using your smartphone. Following trials in the Netherlands, US. and Canada, Mastercard is introducing fingerprint and selfie identification payment options in over 12 European countries. The Mastercard Identity Check Mobile app requires users to blink when prompted to complete online and app-based purchases. This new feature will be rolled out to areas outside of Europe over the next year.
