IDFC does not have credit card business in all locations where they have branches. They mostly do CC business in TIER 1 cities I believe.
I applied for one 2 days back and got the virtual card in 45 min straight. Process was the best I have seen till date. I hold no previous relationship with them.
It is disappointing that there is no clear indication to why the application was rejected but which other bank does that? You can say that the internal policy one liner as an industry standard for rejection. 😉
Also they started CC business just 1 year back or so.
Hopefully in future they will extend their CC business PAN India and everyone can apply for one.
