MoneyBack+ and Millennia are two popular cash-back credit cards from HDFC Bank. The MoneyBack+ is a revamped upgrade that was launched recently in place of the old MoneyBack. Given that, HDFC Bank allows only one credit card per customer which one to go for when we have both options.
Though the product pages of Millennia and MoneyBack+ mention a joining/renewal fee, they are issued Lifetime Free in most cases. HDFC Bank is issuing these Lifetime Free currently as well.
