SFI offers a number of ways to make payments so a credit card is not a necessity. I've seen other answers on your question where you were told where to go to see these possibilities - so I don't want to waste your time by repeating what others have already said.
Besides these other payment methods you can also follow another route. Use your MRP and t-credits won or earned to buy more t-credits, play games or bid on auctions with double MRP attached - to get the MRP but not to win the auction. Just make sure you bid on something you can use should you actually win the auction.
Concentrate on advertising to recruit affiliates and to make sales - this way you earn money and once you earned enough you can get the SFI card - which would immediately solve your problem of no credit card. Once you have that card you can do all your SFI income and expenditure through it - and it is you business card.
