I don't mean to sound forward but what's your background? What's your experience in mobile payment? It's hard to convince someone to put credit card info without giving much info about the company.
While we have no concrete experience in mobile payments, we have a good idea of the current state of the payments landscape. We are developing PaySimply on the side now and this is mainly a market test. We will be using Stripe/Paymill as a payment processor in this test, so everything is secure and PCI compliant. Should we include this in the landing page? We wanted to keep everything as simple as possible.
And no problem for sounding forward. It's best to be as brutal as possible :)
