Ok, so here's my situation:
Is there any safe way of verifying the 'user'. In other words, can MY client be sure that he is receiving valid order forms and not just order forms from spammers (I'm not talking about a simple recaptcha embedded). It's a complete waste of time if someone orders R1000 worth of produced goods and the person ordering it turns out to be a spammer. I was thinking of a direct bank deposit, but would like to know other recommendations as well. What do you guys recommend for a situation like this?
