Not necessarily. We applied for a second BizBlack card in my family without HDFC savings account. I had the account with bank and same card, but said family member didn't had any relationship. Application went thru and card was approved in-principle (as all formalities were met); but was later denied.Is it mandatory for hdfc biz black approval to have hdfc savings or current account?
Spoke with RM on my behalf (with Imperia status) that we will be adding the said member to family banking; and now the card is approved and dispatched; still haven't opened the account though.
So they are flexible, provided you know which screw to tighten with HDFC!!
