@vivi here is an article showing steps for adding your bank account information: How do I set up or change my bank account in SAP C... - SAP Concur Community
If you do not see the Bank Information option, it might be that your company doesn't have the feature set up for the Group you belong to in SAP Concur.
I'm not sure what your question is about the credit card number. Will you be using SAP Concur Travel?
Also, if you could post in English, that would help me help you more quickly. 🙂
