Prime Minister Narendra Modi in a surprise address to the nation on Tuesday night said currency of Rs. 500 and Rs.1,000 will cease to be legal tender from midnight on Tuesday. He said the decision was taken to root out the menace of black money and corruption. New bills for Rs. 500 and Rs. 2,000 are being printed and will be sent to banks. They will be in limited supply initially, necessitating a cap on how many are available to an individual. The new 2,000 rupee note, said the Reserve Bank or RBI in a statement, will include several features like a see-through register with the denominational numeral 2,000 which can be seen when the note is held up against light. For the visually-impaired, there will a raised print of Mahatma Gandhi's portrait, the Ashoka Pillar emblem, bleed lines and identity marks. The latest move is estimated to more than double annual growth at online payment companies. The note will also have a colour-shifting windowed security thread with the inscription 'भारत', RBI and 2,000. The colour of the thread will change from green to blue when the note is tilted.
