Frequently Asked Questions (FAQ)
Is Bento a Credit Card or Debit Card?

Bento is a commercial prepaid debit MasterCard. You can use your Bento card at any establishment that accepts MasterCard. Bento is a credit card alternative that you can swipe as a credit card. If a merchant asks “credit or debit?” it’s ok to say credit, and because it is a business prepaid debit card there’s no credit risk since the card is funded with cash from your bank account.
How does Bento work?

After you sign up, you connect your bank account and safely transfer funds into your Bento account. All of the Bento cards use the same account, so you don’t have to move money between people/card accounts. The business owner or unlimited number of other admin’s can set spending controls for each card, and can create additional cards at any time by logging into Bento. Cards are mailed to the business owner immediately after they are created in Bento. Your first card is created and mailed to the business owner immediately after signing up, and is in the business owner and company’s name. The business owner must activate all cards before giving them to employees.xxxxxxx

from FAQs, funding source of this prepaid is your bank account.

OP, although this is a debit card, in order for it to be useful for MS, it MUST allow funding to come from a credit card without getting charged cash advance. that's how you can profit from it, using your bank account to put funds on this card has no benefits I can think of right now.

Even if one has a legit business that they'll approve, I don't think this will be useful for MS unless I missed something.
