To compare 1D and 2D barcode scanners, it’s helpful to know which
scan engine reads what type of barcode.
1D barcode scanners
Laser scanners are the most popular type of barcode scan engine because they can scan barcodes at distances greater than two feet. However, they only read
linear, or one-dimensional (1D), barcodes such as UPC-A, which is widely used by retailers and grocers.
Another example of a 1D scanner is a
linear imager. Unlike a laser scanner—which uses a beam and mirrors to read barcodes—a linear imager captures an image of a 1D barcode to read it. Linear imagers are a great option when scanning barcodes that are less than two feet away.
2D barcode scanners
The Datalogic QD3400 is a 2D, general purpose barcode scanner that is used for a variety of tasks.
Two-dimensional (2D) scanners can read both 1D and
2D barcodes. They can also read damaged or poorly printed barcodes, which makes them ideal for environments where reliability and flexibility are important.
Companies with field service personnel prefer
2D barcode scanners because they can capture images of documents and signatures, which minimize their risk of fraud. They can also read barcodes from any angle for complete and accurate scans.

Which is best for you?
Because of their versatility, 2D barcode scanners are quickly replacing 1Ds as the scanner of choice for most organizations. However, they aren’t always a perfect fit for everybody.
