You can get the manual 'knucklebusters' on ebay or at many different places online - they'll run $20-$60. The plate with your company name would be about another $15, and the forms are pretty cheap. You don't *have* to have one, but I know I wouldn't use my card unless someone had a proper terminal, either electronic with direct hookup or a manual one using "real" credit card forms. I use Propay - at night I run the numbers through, haven't had a bad one yet. All you need to enter is the cc number, expire date, amount, and zip code. You can input name/addy/cvs code if you want
