Payment Module for using credit off mobile phone account?

Hello all, I created a site about a month ago now and I have been doing a bit of research for it. My site sells peoples music productions for a 50/50 fee between me and the producer. However after doing allot of research I discovered that 30% of my custom go away as there 16 or under and do not hold a bank card. I do have PayPal setup but I found that the 30% of people I spoke to wished there could be a payment module such as mobile phone pay i.e. they pay for track by using credit off their mobile.

I am now looking / scouring the web to see if there is a payment
module available for Zen cart.

I am announcing this because I would be grateful if anybody knew anything about this or were I could get such module. Until this was brought to my attention I never realised how much custom is lost due to this. So it seems to be a great way to pay.

Thanks
Stuart.
