Anyone doing business on the Internet must accept credit cards.
Your success depends on it. 99% of all transactions online are
made using credit cards. If you don't accept credit cards as a
form of payment, you'll not only be missing out on a huge
windfall, you'll also be setting yourself up to fail.

Accepting credit cards offers your customers convenience, while
projecting an image of reliability, credibility, and
professionalism. It says to the world that the banking
establishment has put its trust in you, and recognizes you as a
responsible entrepreneur. In many people's eyes, if you're good
enough for the bank, then you're good enough for them.
