Hey MsCheyenne, Credit card processing can and should remain your primary billing mechanism, not least due to the rebills. But alternative billing can also add to your bottom line. For traffic fom countries with high fraud or low card penetration, check out
www.password-by-phone.com whereby surfers pay you on a per minute basis. They can also be used in conjunction with CCBILL's cascade feature.
Also, for the unbanked or digitally nervous, you should consider accepting cash, see sig.
Happy new year btw :-)
