NAV's digital receipt reporting from September 2026 is a sensible bridging step before the wider online cash register phase out by July 2028. For retail and hospitality businesses still on traditional registers it is going to require either a hardware upgrade or a software route to digital reporting, either way there is cost. The fact that the existing online cash register network is being phased out gives some reassurance, NAV is committing to the digital reporting model rather than trying to maintain both indefinitely.
