Prepaid business cards are not credit cards because you're not borrowing any money. Instead, you're depositing a balance from an account onto a card to be used by employees.
A business credit card is where you borrow money on a card to pay for goods or services and then pay that amount back later - potentially adding interest if you fail to repay everything by a specific date.
To get a business credit card, your business will be subject to a hard credit check. There's no need for a credit check to get a prepaid business card.
