How do I link my existing debit/credit cards?

Just like bank accounts, connecting your debit and credit cards is just one click away. When you sign up, you can choose your card issuer from the list of banks and the card issuers screen. Go on to provide your online credentials and the rest will be taken care of by Line automatically.

If you want to add more cards later, you can go to the left Menu section > Settings > Account & Security> Bank Accounts > Link another card
