POS network best practices

This guide provides tips on how to set up your network to improve the reliability of POS and card terminal performance. 

Follow these network best practices

1. Use a segmented network with a dedicated POS network. Do not set up your POS devices and card terminals on a shared public WiFi network.
2. Use a DHCP server to define unique static IP addresses for your printers and card terminals.
3. If you use intrusion detection (IDS) and prevention systems (IPS), make sure they are using up to date firmware and signatures.
4. Connect your cash registers and terminals to an uninterrupted power supply (UPS).
5. Consider having a cellular backup connection:
    
   • Have an automatic cellular failover on your main router
   • Have a back-up 4G/3G router
   • Have card terminals that have a built-in cellular connection, such as P400m.
      
6. Follow the ROLLER Payements card terminal network configuration recommendations.
7. Make sure to engage an IT professional if you need help setting up your network. Each venue's network setup will be unique; a professional can help ensure the best results for your venue.
