PM Modi will launch NCMC services on the Airport Express Line on Monday. After the launch, commuters will be able to use the NCMC on any corridor of the Delhi Metro. The idea of NCMC was floated by the Nandan Nilekani committee set up by the Reserve Bank of India. NCMC will allow passengers with RuPay debit card, issued in the last 18 months by 23 banks, including SBI, UCO Bank, Canara Bank, Punjab National Bank etc, to be swiped for Metro travel.

Prime Minister Modi in March 2019 had launched the indigenously-developed NCMC to enable people to pay multiple kinds of transport charges, including using metro and bus services across the country.

Dubbed as ‘One Nation One Card’, the inter-operable transport card allows holders to also pay for their bus travel, toll taxes, parking charges, retail shopping and even withdraw money.

The NCMC, which will be fully operationalised on the Airport Line will also be a major milestone as anyone carrying a RuPay-Debit Card issued in the last 18 months by 23 banks (all these are NCMC compliant as per directions of the Department of Financial Services, Government of India), from any part of the country will be able to travel on this line using that card, the Delhi Metro said.
