PM Modi launched the National Common Mobility Card (NCMC) on Monday at the inauguration of the first phase of Ahmedabad metro train service. 

According to the Economic Times, the NCMC is an indigenously developed card that will allow users to pay for multiple kinds of transport charges across the country. The inter-operable transport card can be used to pay for toll taxes, parking charges, and even retail shopping.

PM Modi further added how only limited countries have this technology that has been developed in the country itself. 

Our dream of 'One Nation One Card' has been realised. People can also withdraw money using this Common Mobility Card. This RuPay card can be used for travelling in metros in any part of the country. In simple terms, we have merged the RuPay card with the mobility card. Now, we have this 'Made in India' card. Only a select few countries have this technology of 'One Nation One Card'.
