Frequently Asked Questions

‍

What is the difference between a secured and an unsecured credit card?

‍

A secured credit card, like the Capital One Platinum Secured Credit Card, requires a refundable security deposit that typically determines your credit limit. An unsecured card, such as The American Express Blue Business® Plus Credit Card, does not require a deposit and extends credit based on your creditworthiness.

‍

Can I apply for a business credit card without a registered business?

‍

Yes, you can often apply for business credit cards as a sole proprietor using your Social Security Number. This is a common option for freelancers, gig workers, or anyone with a side hustle who wants to separate their business and personal expenses.

‍

Which type of card is better for building credit from scratch?

‍

A secured credit card is specifically designed to help people build or rebuild their credit history, as they are generally easier to qualify for. Most business credit cards, by contrast, require an existing good-to-excellent credit score for approval.
