Barcode scanners are used to decrypt the QR codes on the item labels. This system comprises of a digital technology where information regarding an individual item is stored in a database that can be accessed via a data collection terminal and by a scanner. The first of this technology was used in motor industry, and it was credited for its ability to enable stock tracking as well as improve management of orders.
There are three major types of barcodes, and these are; the One-Dimensional which commonly uses the line-like UPC, used to label items in shopping malls and retail markets, the Two-Dimensional codes, the commons being the QR-code, and the Three-Dimensional code, this is a recent innovation. All these systems require different scanners each, to read and interpret due to the difference in coding dynamics.
Types of Barcode Scanners.
* The fixed scanners, this type of scanners are mounted and fixed on specific positions like on the retail shop front desk. They use a laser beam to scan and read mostly the one-dimensional code on items to reveal the price.
* Wearable or portable scanners, as the name suggest they are carried around and can be in different makes such as wrist bands or finger scanners. They also majorly utilize laser light to read and scan for the item details. These devices vary in sizes to suit the preference of the bearer.
* The computer or phone scanner, these scanners make use of software installed on their operating system and by the aid of the phone camera, they capture the barcode image, and the software interprets it.
* 3D scanners, these are used to scan for the Three-Dimensional code which requires more thorough scanning since they are embossed on an item, and a scanner must pick the code from all angles.
Scanners connect with the data storage unit either wirelessly or through cords. Majority of the portable ones does not have cords and instead use radio waves of internet connection to retrieve the data. Different scanners work suitably under specific conditions such as weather and perimeter distances between the data source and the scanner itself. It is also advisable to have the knowledge of the type of code you intend to be reading whenever you are purchasing for a scanner.
To conclude this article, I suggest you familiarize with this new technology that is widely getting employed all over the world to enable swift management of products and improve security in the business industry.
