Is anyone familiar with (or even know the name of) the script used at SFI Pay and apay.biz. From the looks of things, they're the same script which leads me to believe it's a commercial product.

Thanks!

looks like the solarpay script just search it on yahoo or google or whatever u use
from what ive heard it has some security issues

It maybe Diesel Pay script.. Take a look http://www.dieselscripts.com/diesel-pay.html
