I need some help. I am planning to write a web site (either in ASP.NET or PHP). which will sell stuff on the internet. I am learning Zen Cart and NopCommerce Framework for the shopping cart implementation. I have also started the process of purchasing the https certificate. I want to know will the credit card payment be made (I evaluated google checkout and it doesn't meet my requirement). I am not clear of the process of how my site can accept credit and debit card payments. Should I approach a bank like icici and ask them to give me guidelines on how payments can be accepted by my site and processed by them? Kindly connect the dots for me... how will my website accept the payment, how will it be routed to bank/visa... how will payment actually occur. What do I need to do, to make this technically happen.
