Serialcarder it’s true they won’t generally want to issue cards to people above a certain age (60 or 65 yrs).
I recently applied for SBI CV Prime in my father’s name using his existing regalia card which has a >5L limit. Application went through smoothly and is approved as well - pending receipt of card. I got it done offline through a mall kiosk with sbicard agent as I do not trust their online application process much. Although agents were not much better - they make lot more mistakes but are easier to follow up with and chase in case of rejection or other application issues.
Planning to do the same for Axis Vistara card as well and let you know how that goes.
