Review on NADAMOO 2D Wireless Barcode Scanner with Stand - USB Cordless Image Reader, Capture QR PDF417 Bar Codes from Paper and Screen, Auto Sensing for Supermarket, Library, Inventory Management by Marfel Fekete
Limitations for linear (1D) barcodes
If you use for linear barcodes (1D), you must have blank areas at the top and bottom, otherwise the scanner will get confused and won't recognize the linear barcode. Don't have barcode listings that are close together. Clearance required at top and bottom.
- CMOS imaging: Using a digital imaging CMOS sensor with a resolution of 300,000 pixels, which can recognize 1D and 2D codes from a screen such as a computer monitor, smartphone or tablet and so effectively that Compensated for problem that the laser scanner cannot determine the screen code.
- It's OK
