QR code and barcode scanner
This scanner reads QR codes and barcodes with your phone camera in the browser, with nothing to install, and keeps what you scan in lists you can export. It is free, and once the page has been opened one time it also works with no network.

How to do it
- Open the scanner and choose a mode: Stock count, Check-in or Verify run.
- Start the camera and point it at a code. The rear camera is tried first, and you can switch camera or turn on the torch.
- If the camera is blocked or missing, scan from a photo or type the code instead.
- Open the list to review the codes, then export a CSV that opens in Excel.
Three modes for three jobs
Stock count: scan each item, and a repeat scan adds one to its quantity. You can fix a quantity with plus and minus and give a code a product name.
Check-in: the first scan of a ticket lets it in, and a second scan is stamped VOID. Import a ticket list first and a code that is not on it is turned away.
Verify run: import the codes you printed, scan them, and see what is missing. Worked example: you printed 3 codes and import them. After you scan two, the list says 2 of 3 found, and the third is marked Missing. A code you scan that was never in the run shows as not expected.
Your lists stay on your device
Lists are saved in this browser. If the browser will not let the page save them, the scanner says so, and they stay on the page only until you close it, so export a CSV before you leave. Several lists can exist, with rename and delete.
The CSV has the code, product name, quantity, format, last scanned time and status, and opens in Excel. The camera needs a secure https page, which is why a page opened another way shows a message and offers photo or typing instead.
Offline and what it reads
The decoder is a small WebAssembly file served from the app itself, not from the internet, so after one visit scanning works with no connection. It is the same reader the generators use for their scan checks, and it reads many formats, including QR codes, Data Matrix, EAN, UPC and Code 128.
Questions
Does it open links from codes?
It lists the text of the code. It does not open a link for you, which keeps a scan from sending you somewhere unexpected.
Why does the camera not start?
The browser may have blocked it for this site, no camera may be found, or the page may not be on https. The scanner names which one and offers photo or typing.
Do my scans leave my device?
No. Codes are read in your browser and the lists are saved in it.
Can I scan from a picture?
Yes. Use Scan from a photo, and if the picture is blurry or far away the scanner tells you no code was found.
