This isn’t about going cashless. It’s about making cash smarter. The RBI will drop 2 billion plastic notes into circulation; 1 billion of each denomination; to see how long they last, how secure they are, and whether they actually save money in the long run. Paper notes wear out fast in India; especially low-value ones handled thousands of times. Polymer could cut replacement costs, reduce waste, and even fight counterfeiting with features like transparent windows. The government says this is just an experiment; no plans to phase out paper notes yet. But if the trial works? This could quietly change how we use cash for years to come.
