India gives RBI go-ahead to test polymer ₹10 ₹20 notes

Polymer notes last 2-6 times longer

1 billion notes each of ₹10 and ₹20 will be rolled out for field trials, but do not worry, paper cash is not going anywhere yet.
These plastic notes last two to six times longer than paper, which means fewer replacements and less waste.
Over 60 countries (like Australia and the U.K.) already use them because they are tougher and more eco-friendly.
