Heather - good info... Porn is an impusle buy, but its also a product where people will do alot of things to get their hands on it
Offering offline payment option should be seen as a last billing option, when credit cards, dialers etc. doesn´t work. I know we are getting contacted by surfers in some Arabic countries wanting to buy access, but do not have credit cards, and dialers are blocked by their country... theres not much we can do, but tell them to get a credit card - this would be different with ex. western union because they are already widely spread in most countries (we do not accept western union payments - yet).
Western Union QuickPay sounds like a good idea. Surfers only need to know 3 things to send you a payment, company name, company code, and their reference (temp memberID or their e-mail address). A few mins after they send the money, then you (or a automated system) will know, and can activate his account (the whole process on the paysite could be automated - no need for anyone to manual check or enter any infomation).
The money are settle into your bank account 2 days after.
I would think this is the best offline payment option, because it can be automated on the paysites. The payment option is world wide. Accept different currency - settle in US dollars. Money are somewhat secure since they use the Western Union network. Only drawback is that surfers need to go to a western union agent, but if there are no other choice, then some will go that "extra mile" for porn
