I had asked tata neu customer care first, they said contact with hdfc bank customer support. Hdfc customer support said minimum 1.75 lac required to upgrade in infinity my credit limit 1.55 lac, I also tell them many people get upgrade at 1.50 lac but denied and said minimum should be 1.75 lac...
Yes, It's free of cost. I had a change in January for a regalia visa to rupay no charge on it and also confirm with customer care by email to be safer side.
Yes you can change the csc card network to rupay card then hassle free upi payment. But there are no benefits from this card it is useless card from hdfc.
I am holding hdfc business moneyback card with limit of 125000 but there is no upgrade offer on it. Since I am thinking about hdfc neu card is it worth taking it.
