You’ve probably seen the image of four blocks with lines flowing through them to make a grid pattern at some point or another, whether it be when using an online shopping app or scanning a product at the grocery store. What you may not have realized was that this image was actually the QR code-a machine-readable code that can be read and processed by smartphones in order to access content such as websites, text, or email addresses. This QR code guide will teach you the fundamentals of QR codes, including how they function and the many ways in which they may be put to good use.

In order to store up to 4,296 alphanumeric characters, a Quick Response Code is a two-dimensional barcode. It is the most popular form of encoding data in the world, and it has been around since 1994. The QR code was supposedly invented in 1994 by the Japanese company Denso Wave Inc. for the Toyota Motor Corporation. The use of this technology has since expanded into other fields, including marketing and entertainment.

QR codes can be used in a variety of ways, from linking to relevant information on mobile devices to playing interactive videos or games. While most people find it helpful to be able to scan QR codes with their phones, it’s important to keep in mind that doing so might reveal a lot about you if you don’t know what you’re doing.

Type 1 (Model 1) is the most common type of QR code. It is possible to store up to 2MB of data, or 4,296 alphanumeric characters. Model 2 codes have the same storage capacity and size as Model 1, but there is additional flexibility for error-correcting levels. Micro or Mini QR codes are typically square shaped and less than 10% the size of model 1 codes. They can only hold up to 256 symbols, but they’re great for storing URLs or contact information. IQR codes are an even smaller version of the micro code and can only hold up to 16 symbols. SQRCs combine the greatest qualities of model 1 and micro codes into a single code that is small enough to fit in the subject line of a text message, or email yet has a vast storage capacity of 26 bytes.

Creating a Quick Response Code is easy! All you need to do is take any message, URL, or contact information and put it into a square. This square can then be read by scanning the code with any Smartphone device. The amount of detail that your QR code contains determines what type of code you will use.
