The first barcode scanner found its use at a store in Ohio in 1974. The clerk scanned the UPC on a product. It changed the way of payment. The UPC barcode was 1D in nature. It integrated the digital and the physical world. A product with a barcode could scan, and access data in the barcode for payment. The 1D barcodes could carry a small amount of data. To carry and read large amounts of data, stacked 1D came into the picture. But, the piled data was not only difficult to read but also large.
To resolve this situation 2D Barcode got introduced. It could store large amounts of data, readable and compact in size. It carries data in the vertical and horizontal directions. It can hold a large amount of information from tens to hundreds of information.
Advantages of 2D barcode scanner
· One of the advantages of a 2D barcode scanner is to read more data, less storage space, and decoding. QR code is one of the examples of a 2D barcode.
· 2D barcodes are in almost all industries. The 2D barcode scanner reads barcodes in all directions. The image sensor reads the barcode irrespective of the position of the scanner. It then directs it to decoder software. The software reads all characteristics on the barcode. The position of the scanner does not matter reducing fatigue and the number of reads.
· The technology used in barcode sensors and a digital camera is the same. The only difference being, the barcode sensor uses a greyscale image. The 2D barcode scanner is capable of taking the picture on the barcode and sending it to the computer.
2D barcode scanners are reliable and there is only one moving part, the trigger switch. The trigger switch technology reads images in a particular fashion. There is no failure and run downtime. With this, you only have happy customers at the store or while scanning the barcode.
Disadvantages of 2d barcode scanner
Pricing: 2D barcode scanner price is higher than the 1d barcode. It is a new and emerging technology. Though it has gained prominence and is used across industries, it is still an evolving one. As it has more than one technology involved, the 2D barcode price is higher.
Distance:One of the disadvantages of a 2D barcode is the reading distance. It lacks reading distance capabilities. The UPC reading scanner can read at a distance of 2 inches as well at a 10 inches distance. The 1d barcode scanner can read at a near distance of 2 inches and 18 inches distance. 2D barcode scanners can read from a 3 feet distance. The most used are the gunshot, cordless ones, mounted style ones and the countertop ones.
There are leading 2D barcode scanner suppliers in Pune. There is a wide range of barcode scanner options. With 2d barcode scanner billings, payments are much simpler. You can see it everywhere. Be it a QR code for shopping, reward points, product billings and online communication (e.g. Web Whatsapp). It has taken over the manual billing system for the better and to only evolve further in the coming years.
