Reserve Bank of India (RBI) published Rupees 10 polymer notes recently. The note is made of polymers (plastic) in the place of normal cotton notes. Yes, the notes we use today are made of pure cotton, not paper. The plastic notes have the lifespan of 5 years which is 5 times greater than normal notes. It doesn't get dirty. RBI destroys thousands of currency notes every day. We have been facing currency problems.

It is not less than a miracle that now blinds can see their surroundings with this innovation. Scientists of WICAB Inc. got success in developing a gadget called BRAINPORT which demonstrated the ability to interpret images for a human brain.
