There are chances that you might get a fake currency during any transactions. Circulating a fake currency is an offence and it is very difficult to detect fake currencies. It is always a good idea to check for the genuineness of the currency when you get any note. Reserve Bank of India has started a new website that helps to detect fake currencies. It is http://www.paisaboltahai.rbi.org.in/
The site which means “Paisa can talk” gives details about the features present in a genuine Indian currency note. One can find the features of 10, 20, 50, 100, 500, 1000 Rupee notes in this website. Besides these, there are downloadable posters and films which bring awareness about fake currencies.
