I have started using less cash too. I have noticed that there are less people trying to trick me when I use less cash. Just QR code works.No drama on change. No getting chocolate for 1 buck when you lack change. A lot of bad people can be kept away when you use digital cash.

No drama of debt and other cash based issues. In short I am going to welcome this cashless world though there are big issues too but better go forward than back. :)
