A VMS vendor is saying that they support "Unified PoS", which is an NRF "architectural specification for application interfaces to point-of-service devices that are used in the retail environment." It claims that "UnifiedPOS provides a consistent and exact framework for programming point of sales devices that is platform independent and vendor neutral."
It's like the ONVIF of PoS integration.
Anyone have any experience with this or using it with any VMSes?
