Yesterday only I have applied Coral card from my branch and It is LTF.
I already have HPCL coral and Amazon LTF and have applied third card Coral as LTF.
After reading this thread, Just now I check with my branch and they said, you will get Rupay but it will be chargeable card.
So, Coral visa, Mastercard and Amex is LTF, but
Cora Rupay is chargeable.
