Hi Julie, thank you for your reply. I’ll search a way to use a debit card, since I’ve only credit cards and I do not trust the way Stripe works. I develop plugins to manage credit cards processing gateways and I don’t like embedded solutions (As you say, I’m just not comfortable with them). By the way, there’s at least one person who think that Stripe solution is not PCI compliant (http://pciguru.wordpress.com/2013/06/30/developers-beware-stripe/ )
I don’t really mind PCI compliance, since I prefer real security (which, in this context is: if I don’t give you my data, there’s no way you (or others via you) may use it).
I’m writing this just to give my 2 cents, not asking for other methods, I hope to find a way to pay with a debit card.
