Dec. 1, 2006 -- OzoneCard International has unveiled a new credit-card service for businesses, offering a line of credit up to $50,000 without cash repayment, the company said Friday.

Under the new service, businesses can pay off purchases by accepting the OzoneCard as receipt for payment from other cardholders. The card has no monthly or annual fees, but can only be used for purchases from other OzoneCard merchants, the company said.
