Frequently Asked Questions

‍

Do I need a good credit score for both cards?

‍

The American Express® Blue Business Cash Card generally requires a good to excellent credit score for approval. In contrast, the Capital One Platinum Secured Credit Card is specifically designed for individuals who are building or rebuilding their credit history.

‍

What is a security deposit for a credit card?

‍

A security deposit is a refundable payment required to open a secured credit card, like the Capital One Platinum Secured. This deposit usually determines your credit limit and is returned when you close the account in good standing or graduate to an unsecured card.

‍

Can I use a business credit card for personal expenses?

‍

It is strongly advised to keep business and personal finances separate for accounting and liability reasons. Using a business card for personal purchases can complicate tax reporting and pierce the corporate veil, which protects your personal assets.
