I haven't faced a single problem with it in Hyderabad, Bangalore and Goa (Paytm, Pine Labs, ICICI, Axis, HDFC POS machines iirc) . With the chip, the card gets marked as "Rupay" network on the receipt. The contactless payments do not work at all unless it's a HDFC POS machine. Also, it gets marked as "Diners Club" network on the HDFC POS machine.
