QR Codes, PDFs, and Mobile Access
How sticker purchasing works, what happens when you scan a QR code, and how PDFs are generated and reused in the field.
Buying QR stickers
QR stickers are purchased at the company level. After entering the desired quantity, the system sends the user to Stripe checkout. Once payment succeeds, the QR inventory becomes available inside the company workflow so each sticker can later be linked to a specific procedure.
Examples
- Order a small batch for pilot rollout on one line.
- Order by area so each department owns its sticker inventory.
Linking and unlinking
A procedure can be opened and linked using the Link QR action. The user can scan the sticker with the camera or manually enter the UUID. If equipment changes, the sticker can be unlinked and reused elsewhere. The system also checks whether a QR code is already linked before allowing reuse.
What happens when a worker scans a sticker
The public scan route reads the QR UUID, looks up the stored PDF reference, and opens the associated document in an embedded viewer. If the QR code is invalid or has not been linked yet, the user sees a clear status message instead of a blank page.
Tips
- Link the procedure before applying the sticker to equipment.
- Test scan one sticker from each shipment before broad rollout.
- If a PDF was just updated, give the regeneration process a moment to complete.
PDF regeneration and downloads
PDFs are part of the normal procedure lifecycle. Download PDF is available from linked procedure rows, and shared-step updates can trigger background regeneration for all affected procedures so field documents stay aligned with the latest edits.
