5 Ways to Use a QR Code

a convenient way to store all kinds of data in a small space

The QR code term stands for Quick Response Code. QR codes are square barcodes (two-dimensional barcodes) that were first developed and used in Japan. Like any other barcode, a QR code is nothing more than a way to store information in a machine-readable optical label. The data contained by a QR code can be anything from simple text, to email addresses, to phone numbers and so on.

QR codes store data using patterns of black dots and white spaces, arranged in a square grid. These patterns can be scanned and translated into human readable information, with the help of an imaging device, like a camera or a scanner, although the most common way to scan QR codes nowadays is to use your smartphone’s camera and a specialized app for reading QR codes.

Why are QR codes useful?

 QR codes are easy to generate and use. They are a convenient way to store all kinds of data in a small space. If the data you want to store in a QR code is made of only alphanumeric characters, a single QR code can hold up to 4000 characters.
 
 The truth is that you can store lots of types of information in a QR code and it all depends only on your imagination. For example, you could also use a QR code to point someone to your Facebook page, or you could use it to display a poem you wrote. It is all up to you.
