Is this inventory scanner really free, with no login?

Yes. There's no account, no trial, and no upload. The inventory scanner runs entirely in your browser. Items live in your browser's localStorage on the device you used to add them.

Where is my inventory data stored?

Locally, in this browser's localStorage on this device. We never send your items, quantities, or notes to a server. Clearing your browser data or switching devices will remove the list — export to CSV first if you need a backup.

Which barcode types can I scan into the inventory?

Any 1D or 2D format that this site's underlying decoder supports — EAN-8/13, UPC-A/E, Code 128, Code 39, ITF, Codabar, QR, Data Matrix, Aztec, PDF417. You can also paste or type any barcode value manually, so unsupported formats still work.

Can I use this as a warehouse barcode scanner on my phone?

Yes — it's designed mobile-first. Open the page on your phone, tap Start camera, and scan items down an aisle. Each scan auto-fills the barcode field so you only need to add the product name, quantity, and location.

How do I export my inventory list?

Click Export CSV. You'll get a standard comma-separated file with columns for barcode, product name, quantity, location, notes, and the time the item was last updated. Open it in Excel, Google Sheets, or import into any inventory or ERP tool.

Can two people share the same inventory list?

Not yet — this MVP is a single-device tool with no login. Two people can each maintain their own list and merge the CSV exports. A multi-user, cloud-synced version is on the roadmap.

About this inventory scanner

This inventory scanner is a free, browser-based barcode inventory system. It pairs a one-tap camera scanner with a simple editable table so you can build a stock list without signing up, installing software, or paying a subscription. Everything stays in your browser — useful for small shops, makers, classrooms, home cataloguing, and field inventory checks.

The same decoder behind our online barcode reader powers the camera here, so it handles standard retail and logistics symbologies. For more detailed validation, open the GTIN validator alongside this page.

When to use it

Doing a quick stock-take in a small shop without a full POS system.
Cataloguing books, tools, parts, or hobby supplies at home.
Building a warehouse barcode scanner workflow on a spare phone before committing to enterprise software.
Scanning incoming deliveries into a CSV that you can hand to accounting.
Teaching students how a barcode inventory system works, end to end.

How it works

1Step 1
Start the camera
Grant camera access once and point at a barcode. The scanner decodes it and auto-fills the barcode field.
2Step 2
Or type manually
No camera? Paste or type the barcode directly into the form — handy for keyboards and wedge scanners.
3Step 3
Add product details
Give the item a name, quantity, location, and optional notes. Defaults to quantity 1.
4Step 4
Edit or delete
Each row has edit and delete actions. Quantities can be bumped in place as stock moves.
5Step 5
Export to CSV
Download the full list as a CSV any spreadsheet, accounting or ERP tool can import.

What to avoid

Treating this as your only copy. Export to CSV regularly — clearing browser data wipes the list.
Assuming the same list appears on another device. Without a login, each browser has its own inventory.
Scanning barcodes through thick plastic wrap — glare often beats the decoder; tilt or remove the wrap.
Using emoji or commas inside the notes field if you plan to re-import the CSV into a strict parser.
Relying on the scanner alone to validate GTINs. For check-digit confirmation use the GTIN validator.

Tips & tricks

Bookmark this page on your phone's home screen — it behaves like a lightweight inventory app.
Use the Location column consistently (e.g. "A1-03") so you can sort by it in a spreadsheet later.
If you scan the same barcode twice, the existing row is highlighted so you can increment quantity instead of duplicating.
Export CSV after each major session — treat the local list as working memory, not the source of truth.
On laptops, a USB wedge scanner types straight into the barcode field. The camera tab isn't required.
