Frequently asked questions
Which formats can it read?
Linear codes including EAN, UPC, Code 128 and Code 39, plus 2D codes such as QR and Data Matrix.
It will not read a damaged label. Any advice?
Try the image upload mode with a sharper, well-lit photo taken square to the label. That often succeeds where a live camera pass fails.
