1D Barcode Vs 2D Barcode

1D Barcode Vs 2D Barcode

One-dimensional (1D) barcodes are linear barcodes,with vertical lines made of varying widths and gaps.

Two-dimensional (2D) barcode, encode data generally in square or rectangular patterns of two dimensions.

Laser scanner or 2D imager scanner? How do you know which one is right for you?

Lasers scanner depend on the reflection of laser light to get a good scan.Due to the nature of laser light, only a thin (linear) slice of the barcode can be read at any one time.Laser scanenr can not scan barcodes on screens as screens do not reflect laser light properly.

Imaging scanner works by taking pictures and running sophisticated image processing algorithms on each image to decode barcodes. With CMOS sensor, 2D Imager scanner can read barcodes from nearly every surface type including computer or mobile device screens, and even scan through glass surfaces, plastic shrink wrap.

If your barcode is 2D barcode or you need to read barcodes off a screen, such as computer monitor, smartphone or tablet, a 2D imager is likely the way to go.

According to the nature of its camera focus and photographing, imaging scanner is not sensitive to read long 1D bar code. If you want to scan one-dimensional barcodes longer than 10 cm /4 inch, we suggest you purchase laser scanner.Generally, when reading 1D long barcodes, laser scanner can read barcode more easily than imaging scanner.
