QR tags on a door register, done once and done right.
A QR label is a pointer to a record. Get the identity, the placement and the access rules right at the start and repeat visits get faster forever; get them wrong and you spend two years peeling labels off doors.
Section 01How to do it
-
01
Fix the door IDs before you print anything
The label is only as good as the ID under it. Agree the numbering with whoever owns the building, get it into the register, and only then print. Reprinting a block is cheap; re-identifying one is not.
-
02
Choose the label format for the environment
Standard labels for internal doors in dry conditions. Tape-printer labels where the surface is awkward, the door gets cleaned aggressively, or a rigid label would be picked at. Both print from the app.
-
03
Decide what a scan should show
Staff scanning to capture is a different question from a resident scanning out of curiosity. Where the record holds sensitive detail, gate it behind the per-inspection PIN rather than assuming nobody will try.
-
04
Place them consistently, and clear of the assembly
Pick one position and repeat it on every door, so a scan becomes a reflex rather than a search. Keep the label clear of everything that makes the door a fire door: intumescent and smoke seals, the certification label and any manufacturer markings, hinges, closers and ironmongery. A label fixed over a component can affect how the door performs and may void its certification, so agree the position against the manufacturer’s guidance and the building owner’s policy before you print a block.

05
Verify on site, not at the desk
Walk the block and scan every label once. A mis-mapped tag found on the day it was fitted costs a minute; found at the next inspection it costs the credibility of the whole register.
Section 02What the app actually does here
- Each door carries its own signed tag ID, so a scanned label resolves to exactly one record and cannot be guessed at
- Batch label sheets print as PDF in two layouts, standard and tape; a single label is saved as an image
- Tags can be printed in advance as an unassigned batch, each one binding to a door the first time it is scanned
- Scanning works from a phone camera through a short link, with no app install
- The door keeps its ID across re-inspections, so history accumulates on one record
- Fire stopping penetrations have their own QR tags, printed as PNG rather than PDF
Section 03What goes wrong
Every one of these has cost somebody real time. They are cheap to avoid and expensive to unwind.
The single most expensive mistake. Every downstream record inherits the ID under the label.
Treat tags as pointers to records, not as credentials. Access control is what protects the record; the label just addresses it.
A label fixed to a fire door is an addition to a tested assembly. Over a seal, a hinge, a closer or the certification label it can affect performance and void certification — and it is exactly the sort of thing an auditor notices. Settle the position against manufacturer guidance once, then repeat it.
Generate a new tag and reprint the label — the door record and its history stay intact, and only the tag mapping updates.
