# Introduction RMH is an on-premises retail point-of-sale (POS) system that requires a robust, appropriately configured, and secure network to function properly. This guide identifies best practices that partners should follow when setting up a store's network to optimize RMH app performance and reduce the risk of service interruptions. Poorly designed and improperly configured networks are the primary source of technical issues that stores experience with their POS system, such as loss of POS lane connectivity, issues with peripheral connectivity and payment processing, and exposure to computer viruses and malware. There are many ways to set up a store's network. This guide focuses on the most common store network configurations. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
