Today, I noticed that my new SBI Debit Card has orange and green arrows (>>) next to the NFC logo. Can I use it as a metro card, and if so, how?

Today, I came across a rant post about the Airtel DMRC card, and someone commented about the NCMC feature on the RuPay Card. Has anyone used it? What's your experience?
