Next-gen tech: Now, dip into digital wallet via watch, ring

How about wearing a wrist watch or a small ring on one’s finger which does the work of a pre-paid wallet of your smart phone.

The wrist watch and the ring are among other devices like key chains and friendship bands that can be embedded with a chip to work like a pre-paid wallet. The Reserve Bank of India (RBI) displayed these devices among the next-generation contactless payment options at the G20 Summit that ended here today. The device can just be tapped at the scanner, provided by the merchant, to make a payment.
