Re: i need to update my credit card details on adwords
If it's only the expiry date that has changed (renewed card) you can do that by going to Billing - Billing Settings, identify your card, click on edit and change anything except the credit card number (you cannot change that).
If it's a new card, do the same, add the new credit card in the same section and then select is as the primary form of payment, if you want.
