Pen Testing Point Of Sales Application

Hi Team,

We are attempting to perform penetration testing on POS (Point of Sales) Application. Did any one come across such testing before. We need some help on how to perform pen testing and what tools are used?

We tried intercepting the traffic in order to conduct penetration testing on POS applications such as Oracle Xstore and Samba POS. However, we are currently unable to capture the traffic. Could you please assist us in determining if Burp Suite supports POS applications?
