I'm already holding 3 cards from axis: Axis MyZone VISA(LTF), Axis airtel visa (chargeable) and axis indian oil master (Migrated from citi) card.. Can i apply for MyZone Rupay LTF card which is showing und Apply Now -> list of cards? Will it replace my existing MyZone VISA card with this? or do i need to close visa card first and then apply for rupay ?
