      If your payment system runs over WiFi, and if that WiFi link and your payment server/client apps also do not implement any extra security measures, then your security is screwed. Anybody with a laptop and some free software can sniff your traffic, insert extra packets, etc. God help you.

      Luckily, most modern WiFi equipment supports the WPA2 standard for link-layer encryption and authentication. If you just enable WPA2 on your router and set a halfway decent password, nobody will be able to bother you. WPA2 is very, very secure (from a cryptanalysis perspective), as good as the best stuff that protects bank transactions, military secrets, etc.

      Or, you might be able to encrypt the app traffic via SSL or a VPN, using app-level passwords for authentication. Depends on what the PoS terminal and server platforms support.

      Either way, make sure you physically lock down both the terminals and the server. If anybody (e.g., rogue employee) can view a cleartext password or modify a security configuration from the PoS terminal UI, or if they can open the case and pull a hard drive, you lose.
