PADS4 is a software platform for digital signage and smart buildings from NDS (Net Display Systems), a Dutch company in Eindhoven. The platform bundles modules for digital signage, workspace management (desks, equipment, meeting rooms), visitor management, wayfinding with real-time occupancy mapping, and flight information displays (FIDS). It targets sectors including retail, manufacturing, the public sector, transport, healthcare and education. The pages consulted do not state a delivery model (cloud or on-premise).
NDS is based in Eindhoven and, according to an M&A transaction listing, was sold to the French company LCS SAS, a provider of digital signage and workspace management solutions; the owner is therefore in France, within the EU. The sources consulted do not say where customer data is hosted or whether a hosted variant exists, so this should be confirmed with the vendor. The software is not open source. For a European organisation this means a vendor with Dutch development and a European owner.
