While xnPOS is generally deployed as a true cloud-based POS solution, local offline redundancy at the property / outlet level is needed to ensure continuity of business and trading regardless of internet availability. This is why xnPOS also enables an OTS (Outlet Transaction Server) to continue to trade locally, with local caching of all transactional postings, in the event that internet reliability or availability is compromised. Thus ensures an always-on POS solution even when it may be hosted in our data centre.
