Demonetisation process is inching towards normalcy and slowly and steadily getting momentum to achieve its end use in unearthing black money. The government asks banks to start using indelible ink to mark and identify persons who exchange old Rs. 500 and Rs. 1,000 notes to ensure that the facility is not used multiple times, even as people continued to queue up for cash to meet their daily needs at banks and ATMs across the country. A small mark of indelible ink, used during elections to prevent multiple voting, will be put on the right hand finger of persons exchanging the recalled currency. If the system works foolproof then we can have an overall control over exchange of notes. But just like in voting people can turn out again and again after erasing out the mark using chemicals and fool the bank staff by picking a different counter to cheat.
