Yeah, maybe they're taking off in India and China because of a "leapfrog" opportunity. For example, pre-paid digital wallets are used to pay for ride-sharing, whereas in the U.S people just use the same card that they already use often at CVS, Starbucks etc. The other aspect that I think a lot of financial innovation will depend on is a "killer app". In India it's been phone 'recharge'--most people have prepaid phones, so you can add balance using the mobile wallet app instead of going out to find a nearby shop or kiosk to do it for you. And in the case of China, WeChat integrates so many services that it makes sense to have a wallet integrated into its many offerings. In the U.S, Venmo is instructive too, about focusing on a product rather than a method or technology.
