- Given the general reluctance of people (only five per cent of all transactions are electronic) to adopt electronic payments (plastic money/online payments), it remains to be seen how payment banks can build a pure transaction fee-based business. There does not appear to be a specific mention of whether or not payment banks will be required to pay interest on the deposits accepted – and if so, whether it will be in line with those for existing licensed commercial banks. Paying interest on demand deposits will translate into significant added costs for payment banks and may make the whole project unviable. - The absence of Internet and wi-fi connectivity in rural belts poses a clear challenge. This can be tackled effectively if the government and RBI become proactive and involve TRAI/telecom companies in providing immediate e-platforms.
