Which Barcode Reader to Choose: Laser or Imager Barcode Reader?

by John Devid Content Writer
Barcode is the next age technology where crucial and important information related to products and their manufacturer are represented in an optical form of various lines and symbols. These lines and symbols are read by an optical machine called barcode readers. The barcode technology has enabled companies to procure their products in a more safe and secured environment because barcodes have sped up the process of tracking and maintaining of the records of hundreds or thousands of items.

With the use of barcode readers, the various symbols and parallel lines are transmitted to a computer device and stored there for further reference. Because of Barcodes and readers’ huge demand in the retail and manufacturing industry, the technology for barcode reader has been evolving ever since. Therefore, it is imperative to understand the various barcode technologies, their benefits, usage and purpose. For instance, there are two types of technology is prominent in barcode readers scanners present. First, Laser barcode scanner and the other one is digital image scanner. This difficult job can be eradicated with a good understanding of the advantages and disadvantages of each type.  Both types of technologies can be effective with their appropriate applications. But for that one needs to know the array of features and benefits provided by the each barcode scanner.

How Does Laser Barcode Reader Works?

This article presents a brief explanation of laser scanning technology, its methodology and advantages. A laser scanner emits a laser beam (with the help of optics that are inside its body) and uses a lens to focus the beam with an oscillating mirror that moves the laser beam line across the barcode very rapidly.  Next, the barcodes reflect the laser beams back to the scanner, allowing the scanner to decode the signals.

The Advantages

Probably, the best benefit of a laser scanner is that it can read barcodes even when these codes are at a distance, making it ideal for long distance scanning. The speed of the transmission of the data is also faster than the other barcode technologies. Laser barcode scanner can read images or symbols in motion; still the accuracy level remains high.

Digital Image Scanner

Digital image readers on the other hand emits LED light that illuminates the barcode and projects the image back to the scanner for decoding.  It is similar to a digital camera, but works much fasterthan that.

One of the advantages of image scanners is that it can read both 1D and 2D barcodes.  It also offers the facility to read the scanned image from any direction because of its Omni-directional scanning. With a digital imager one can even capture images such as a signature or photographs of a damaged box.
