Scan lists for inventory

Keep continuous mode on and scan items one after another: each new barcode is added to the scan list, and scanning the same item again increases its count. Export the list as a CSV file for Excel or Google Sheets. The list stays in your browser until you clear it.

What does “check digit valid” mean?
EAN, UPC and ITF-14 barcodes end with a check digit calculated from the other digits. If it matches, the number was read and printed correctly.

Can I use it for stock counting?
Yes. With continuous mode on, every new barcode is added to the scan list and repeat scans increase the count. Export the list as CSV.
Is anything uploaded?
No. Everything runs on your device and the scan list is stored only in your browser.
