New Delhi, Nov 16 (PTI) To stop repeat money exchangers thronging banks with invalid currency notes, banks have started applying indelible ink mark on the right hand index finger of customers in the select metro cities

SBI and few other banks in Delhi have started using indelible ink. As per the government statement, 11 branches of SBI are using the method to weed out customers queuing up again and again to exchange invalid currency notes

As per the Standard Operating Procedure (SOP) for exchanging notes, concerned bank branches and post offices would put indelible ink mark on the right index finger of the customer so as to identify that he/she has exchanged the old currency notes once

The move comes amid reports of long queues and chaotic scenes at banks and ATMs across the country for past several days after Prime Minister Narendra Modi last week announced the withdrawal of old Rs 500/1000 notes in the biggest crackdown on black money, corruption and counterfeit currency

The notes withdrawn accounted for 86 per cent of the cash circulating in the Asia's third-largest economy

The indelible ink is supplied to the bank/post offices by Indian Banks' Association (IBA) in coordination with the banks and consultation with RBI

This procedure is being introduced to begin with in the metro cities and expanded to other areas later, the RBI said in a statement

Identified bank branches are provided with black indelible ink bottles of 5 ml each and the cap of the bottle includes a small brush for applying the ink

According to SOP released by the RBI, indelible ink can be applied by the cashier or any other official designated by the bank before the notes are given to the customer so that while the exchange of notes is taking place, a few seconds elapse which will allow the ink to dry up and prevent removal of ink

Indelible ink on the index finger of the left hand or any other finger of the left hand cannot be used.
