A 'Scan with camera' button opens the phone's own camera app; the photo is shrunk
on the phone and read on the server with zbarimg, then goes through the normal add
flow (also available on the sticker step). Works over plain HTTP on iPhone and
Android - no HTTPS needed.
- /api/scan: JPEG/PNG only (checked by magic bytes before ImageMagick sees it),
12 MB cap, login required, 20 s timeout, temp files cleaned up
- UPC-A reads (zbar reports 13 digits with a leading zero) normalised to the 12
digits printed on the item so duplicate checks match
- tests/gen_photos.py + tests/check_scan.py: phone-like photos (tilt, blur, noise,
low light, upside down, EXIF rotation, small, UPC, Code 39 sticker); 10/10 read
at the size the page sends

Quick Add:
- barcode choices: automatic (zero-padded, >= 7 digits), scan a pre-printed
sticker per item, or none for now; bulk 'give barcodes to items without one';
reserve a block of numbers and print the sheet ahead of time (link opens
Koha's range printer prefilled)
- default shelf saved on the server (shared by every device)
- item types follow Koha; CSP allows cover redirects; aria attrs fixed
Koha bootstrap:
- default lending rule (3 weeks, 25 items, 3 renewals, no fines) - a fresh
Koha refuses every checkout without one
- automatic library-card numbers (start at 1000001), fines off
- Koha's own auto-barcode off (one numbering scheme)
- patron card template (Avery 5371) and layout with a scannable barcode
- LIBRARY_CODE, SHELVES and ITEM_TYPES honoured at first install
Why 7 digits: decoded printed sheets - 7-digit Code 39 read back 40/40, 6-digit
all-numeric symbols were reinterpreted as Code 32 for ~1 in 10 values.

- Quick Add: choose the shelf/room (Koha LOC values) once; every scanned item
gets it and the choice is remembered; invalid values are ignored
- install.sh --status shows localhost in loopback mode; port probing works
without ss
- library/README.md; kiosk Readme.md add-on section and licenses
