UPI is digital transaction. But still RBI have to print equivalent paper currency. Digital Rupee is electronic currency. There is not much difference whether you use UPI or Erupee. Till RBI not give incentive to Erupee, people will not adopt Erupee. RBI should stop printing above 100 in paper currency. Then people will be force to adopt Erupee. There will be no impact on banking system. Yes there will be merger of banks and employees will be lesser consumed.
