I would like to start a service where by users send in a particular code to partake in, the code gets verified and then if its the correct code the user gets to partake , basically its based on a process similar to how recharging your phone works. However i don't know the exact way which recharging your phone works. Is there a certain system or database which verifies the cards ?
@guddsid, i have a solution that does exactly what you discribe, maybe you might feel like contacting me. sacomtechit@yahoo.com is my mail, will be expecting you mail.
