DCB HDFC DCB add-on card for international lounge access

[devskd]

Hi,
I am planning to give an add-on card to my sister, just for international lounge access.
But I am worried since I have heard international transactions don't require OTP. what all things I can do to make sure card is secured?
also,

1. do lounge access internationally require us to put our pin?
2. Can I just turn on Merchant Outlet Usage in international transactions and set limit to 1000 Rs and give her the card for lounge access and turn off all the rest (online, tap& pay, atm etc)?

1. pin not required AFAIR, if you want to set pin, use mycard web app of hdfc
2. yes. Did the same with all add ons
