The same idea in very different places: put the information on the object it describes.
Give every asset a tag and a page. See who is responsible, where it is and when its warranty ends, without a spreadsheet.
Track tools and equipment with your team's own phones. Every tap is logged, so you can see when each item was last handled.
Put the service history and the maintenance form on the machine itself, so technicians record work where they do it.
Let tenants report a problem from the spot where it occurs. You receive it with the unit and the appliance already identified.
Run inventory checks by tapping each item or shelf. NFC suits low-volume, high-value stock. For bulk counting, UHF RFID is the better fit.
Guests tap for room information and to report a problem. Housekeeping taps to confirm a room is done. No app for anyone.
Record fridge temperatures, cleaning and equipment faults at the point of work, with a time on each entry.
