QR Code Information

Japan started experiencing economic growth back in the ‘60s. This is the same time that supermarkets started out and were selling different commodities that ranged from clothing to food stuff in various neighborhoods.

Cash registers started being used at all checkout counters and they required for the commodities’ prices to be manually keyed in. This in turn saw many cashiers experience wrist numbness and eventually end up with the carpal tunnel syndrome. In turn, the demand for a way to save these cashiers from their agonizing pain grew hence the creation of a POS system. This system was created to prevent people from wrist problems caused by repeated actions for keying in commodities prices in computers.

The POS barcode system

In the POS system, an item’s price is automatically displayed on a cash register when the barcode printed on the item is scanned using optical sensor. Once the scanning took place, the item’s information (mostly name and price) was displayed on the computer screen.

Word about this device spread like wildfire and was subsequently used all over the globe. However, as time went by, its limitations became obvious and people started looking for ways of reducing those limitations. This meant, finding a way these barcodes could store more information and be able to read more characters other than just the 20 alphanumerical characters.

QR Code information

This desire to have barcodes store more information led to the creation of QR codes. Also known as quick response codes, these are 2D codes that have the ability to store different characters including Japanese characters and can store massive information.

These codes also don’t need scanners like those used in supermarkets. All they need is a smartphone that has a QR code reader app installed. The camera takes the place of a scanner.

Here is how you can brand a QR code:

  • Launch the web browser you are using and access an online QR code generator. Make sure the generator you are using has an error-correction feature like that of Visualead.
  • Type the data you wish to encode in your QR code in the appropriate boxes in that generator.
  • Set that error correction feature. It increases the QR code’s size slightly and also increases the code’s performance when a section of the code gets concealed by an image or logo.
  • Click on “Generate” for the code to be created then save it when finished.
  • Open the graphics package your compute has. Drag then drop that QR code image in the workplace for graphics.
  • Resize the code by editing it. Test it then save it to your computer.
