Rs.1000 notes introduced in October 2000 contain a readable, windowed security thread
alternately visible on the obverse with the inscriptions ‘Bharat’ (in Hindi), ‘1000’
and ‘RBI’, but totally embedded on the reverse. The Rs.500 and Rs.100 notes have
a security thread with similar visible features and inscription ‘Bharat’ (in Hindi),
and ‘RBI’. When held against the light, the security thread on Rs.1000, Rs.500 and
Rs.100 can be seen as one continuous line. The Rs.5, Rs.10, Rs.20 and Rs.50 notes
contain a readable, fully embedded windowed security thread with the inscription
‘Bharat’ (in Hindi), and ‘RBI’. The security thread appears to the left of the Mahatma's
portrait. Notes issued prior to the introduction of the Mahatma Gandhi Series have
a plain, non-readable fully embedded security thread.
On the obverse side of Rs.1000, Rs.500, Rs.100, Rs.50 and Rs.20 notes, a vertical
band on the right side of the Mahatma Gandhi’s portrait contains a latent image

This feature appears between the vertical band and Mahatma Gandhi portrait. It contains
the word ‘RBI’ in Rs.5 and Rs.10. The notes of Rs.20 and above also contain the
denominational value of the notes in microletters. This feature can be seen better
under a magnifying glass.
