On the add-on card: yes, the primary cardholder is fully liable for all spends on the add-on. There is no separate credit limit or statement. So only issue it to someone you trust absolutely — spouse, parents. Not friends, not siblings you have money disputes with.
Tip from someone who made this mistake: never max out the credit limit in the first 6 months. Banks track utilisation, and high utilisation right after approval often triggers a credit limit decrease or even an account review.
