Reserve Bank of India has come up with a new feature for 100 rs currency notes to enhance the security. RBI has announced that they have given a new numbering pattern to the hundred rupees notes in order to keep check for fake currency. RBI has issued Rs100 denomination banknotes in Mahatama Gandhi series-2005 with a new numbering pattern and the size of the numerals in both number panels will increase from left to right. But the size of first three alphanumericals will remain same.
