Square has launched a free debit card that will allow small business owners to more quickly tap into the money they receive in payments. Christina Riechers, Square's payments product lead, told Cheddar on Friday that the card was designed to help businesses manage the "tight cash flow gap." With the card, business owners who receive a payment through Square will immediately have access to those funds for business expenses. She said the Square Point of Sale app will also allow them to see all their finances in one place.
