Although it does not look anything like a barcode, it works in a very similar way because it has information stored in the combination and pattern of the dots within the square. The main use for them today is to store the URLs of the company or product and this can be read by most of the mobile phones that are on sale today.
Naturally the company’s marketing department is overjoyed by the introduction of QR codes on company products’ as the camera on the smartphone will scan this and can often open the user directly to the app store, depending upon however the producer wishes this to operate. Most companies decide that the user is directed to the URL and then the website of that company can be accessed which means that the full range of products and other services can be seen. However, QR codes can display information such as a telephone number, or it can compose a text message, or even an email is possible.
QR codes are now found just about everywhere and when you are ordering labels that have barcodes on them, adding a QR code is going to give you an advantage over competitors that do not include them on their labels.
