Hello everyone, so I am going to be developing a website for a friend of mine. He owns this business that allows people to come to his store, pay 20 dollars and play some games. He wants on his website, a paying system, where users can pay 15$ instead of $20, and when they come to his store, he can see they prepaid. I had some ideas on how to do this, but my questions are:
1) Can paypal handle this kind of system, where my website can read if they paid the money and add their name to an MySQL database?
2) If not, then how would I go about doing this in PHP, ASP... etc...
I would gladly appreciate any help. Thank You!
