Technology has penetrated the finance sector so much that it now seems impossible to imagine banking without computers, mobile devices, the internet, and transaction methods like the Unified Payments Interface (UPI). However, traditional cash still retains its significance. According to a Reserve Bank of India (RBI) report, cited by PTI, note circulation has moderately grown over the last three years. Interestingly, currency circulation is still growing despite digital transaction modes. The RBI document says, “Despite moderation in the growth rate of NIC (Notes in circulation) in the last three years, analysis indicates that the growth will continue to be positive over the foreseeable future, though the pace is expected to be slower over the next decade,”.
