A Quick Response Code is a two-dimensional barcode that can hold up to 4,296 alphanumeric characters. It is the most popular form of encoding data in the world, and it has been around since 1994. The use of a QR code is said to have originated in 1994 when the Japanese company Denso Wave Inc. Since then, industries such as advertising and entertainment have begun to make use of this technology.

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 users find scanning QR codes with their phones convenient, there are also potential drawbacks to consider—namely, how much personal information you're sharing if you scan one without being aware of what it does first. Before scanning a QR code, make sure you understand what you're getting into by reading the explanation. You can read more on the subject here!

Type 1 QR codes are the most common (Model 1). It is possible to store up to 2MB of data, or 4,296 alphanumeric characters. Model 2 codes are similar in size and capacity, but they also allow for a greater number of error correction levels. A micro or tiny QR code is often square in shape, making it significantly smaller than a model 1 code (which may be up to 10 centimeters in size). They only contain 256 characters, but that's more than plenty for storing addresses and phone numbers in the current world. The IQR code, which is even smaller than the micro code, can only contain a maximum of 16 characters. SQRCs incorporate the best features of model 1 and micro codes into a single code that is small enough to fit in a text message, or an email subject line yet has a massive storage capacity of 26 bytes.

Making a QR code couldn't be simpler. All you need to do is take any message, URL, or contact information and put it into a square. Any smartphone may read this square by scanning its code. The amount of detail that your QR code contains determines what type of code you will use. This page has all the info you need about QR codes.
