we already did testing of plastic notes in 2014. then suddenly we havent heard anything. we've been interested in plastic notes since 2011. you would get used to plastic notes just like you did get used to colorful notes we have now.50% more for a population like India can be significant. There is a school that opposes giving so much power to some small entity. I don't get the logic here. If already we are outsourcing currency production abroad because we lack the expertise & skill then how does allowing Canada or Australia to do it endanger interests. Maybe they think the Paks might be able to penetrate them easier than say the UK but this doesn't really wash. Maybe they are taking the cheap way out and relying on changing currency more often in the future to stymie the Paks.
I did have some Canadian currency for a while but after the initial novelty of plastic wore off it just felt strange. Also its quite small like these new Indian notes. That physical downsizing gives the impression of devaluation. It reminds me of coins. The 5 rupee coin was thick and heavy then it started to get lighter and it won't be long before it weighs as much as a one rupee coin. Remember what that looked like earlier ? Heavier metal and bigger unlike the parking token of light metal used these days.
and 50% more is something we can afford if we can afford to do largescale experiments like demonitization. Also we print our own currency, we don't outsource our currency production abroad. that would be a huge national security risk. also these new plastic notes can be of standard indian size notes, not necessarily be canadian size notes.
