Card Defender Network Requirements

Modified on Fri, 06 Oct 2023 at 03:49 PM


  • A supported payment terminal
  • An available network cable (RJ-45 end on a CAT-5/6/6e cable) connected to an existing network.
    NOTE: Some credit card terminals support a wireless connection, this is possible to use, but wired is always preferred for reliability.
  • LAN connections should have a 1ms ping response time with less than 0.1% packet loss on average.
  • Internet connections for having a ping response time to Google of less than 50ms and less than 0.5% packet loss on average.
  • If you are providing a “segmented” network to separate the POS terminals from the payment devices you MUST:
    • Be able to ping the payment terminal from the POS device
    • Be able to ping the IP of the credit card processing company from the payment terminal
    • These need to be tested and operational before we will start our work
    • If you don’t know what a segmented” network is, then this likely does not apply to you ?
  • If you restrict outbound traffic with a firewall see the Firewall Ports section below and attached are the list of Ports, URL's and IP Addresses that required by PAX.
