What is a 1D barcode?
Linear, 1 dimensional barcodes are a row of parallel lines of varying thickness. The information is
stored in the widths of the bars and spaces. 1D barcodes are used in retail products.
What is a 2D barcode?
2D barcodes are a pattern of black and white blocks arranged in a square or rectangles. Two
dimensional barcodes can hold significant amount of information and are more typically used than
1D barcodes. 2D barcodes are used for manufacturing, warehousing, etc.
For command barcodes not available in the guide, contact support@socketmobile.com.
After scanning a command barcode, power off and on the scanner to make sure it's
configured.
Note: Most computer monitors allow scanning the barcodes directly on the screen. When
scanning from the screen, be sure to set the document magnification to a level where you can
see the barcode clearly, and bars and/or spaces are not merging.
Make sure the scanner is not connected to a host computer or device before scanning a
command barcode.
