title: How to create payment gateway for an online transaction?
body: <p>In my web application there is an online transaction system for online reservation. I have no idea about how to implement this, i.e when an end user wants to do reservation, a form has to open showing different banks, by selecting bank, user will be allowed to enter his/her card credentials and I have to send this to third party payment gateway vendor and has to receive information from that party regarding the transaction status. </p>
  
  <p>How can we send and receive data from third party or is their is any way that we could eliminate the third party from transaction ?</p>
  
  <p>Please help ! Thanks in advance.</p>
