Don't write on Bank Notes - RBI
IT has been brought to the notice of Reserve Bank of India that members of public and institutions write number, name or messages, etc. on the watermark window of banknotes, thus defacing the banknotes. The watermark window has an important security feature which distinguishes it from a counterfeit note. Any defacement on the window will not allow the common man to identify one of the features of a genuine note.
The RBI requests the public to refrain from doing anything that leads to defacement.
