Asalam o alakiam , My question are credit cards haraam even if i pay the full amount before the grace periods charges interest and if they are haraam can i keep them just for credit scores or ids ?

AAWW

Muslims in the US are exempted from the prohibition of using credit cards because of the dire need of using it in this society.

The above permissibility is stipulated with paying the balance in full before its due date, and refraining from conducting any transaction might incur Riba.
