I have a site which selling UK calling cards, currently i am using E-junkie and Paypal for sending PIN numbers to customer instantly, I have to pay $15 per month to E-junkie, it's really a big amount for me, however there is a little profit from calling cards. I need a script which will send PIN numbers automatically, anything, free or payable. Need a good solution, please help me to find a good result.
I dont want to use e-junkie or similar type solution. If anyone knows where to find the script i will be glad to buy it.
