My firm did several research studies early on in the mobile payments era. Interestingly, the concept of digital/mobile payments is a much more widespread phenomenon when you look at it globally. M-Pesa in many countries in Africa is becoming the default way to send payments since carrying cash in many regions there is dangerous. In India, Paytm has grown incredibly as an alternate form of payments, and certainly in China cash is almost entirely gone thanks to digital wallets and payments mechanisms like AliPay and WeChat pay.
