Create your QR Code for free. Link management and more. A cutting-edge solution to make a connection between your content and your audience. The QR Code is a two-dimensional version of the barcode, usually composed of black and white pixel patterns. Denso Wave, the Japanese subsidiary of Toyota equipment manufacturer Denso, developed them for marking components in order to speed up the logistical processes of their automobile production. Today, it has found its place in mobile marketing with the widespread adoption of smartphones. « QR » stands for « Quick Response » which refers to instant access to information hidden in the Code.
A QR Code, or Quick Response Code, is a two-dimensional barcode that was initially created in 1994 by a Japanese company called Denso Wave. QR Codes can store a variety of information, including numeric, alphanumeric, binary, and Kanji characters. They have gained widespread use due to their ability to store large amounts of data and their quick readability.
There are several types of QR Codes, each designed for specific purposes. Here are some common types:
Numeric QR Code (Numeric Mode): This type is used for encoding numeric characters (0-9). It's suitable for applications that require only numerical data.
Alphanumeric QR Code (Alphanumeric Mode): This type can encode alphanumeric characters (0-9, A-Z, and some special characters). It is commonly used for encoding website URLs, contact information, or any data that includes both numbers and letters.
Binary QR Code (Byte Mode): This mode is used to encode binary data, making it versatile for encoding any type of data, including images, audio, and other binary files.
Kanji QR Code (Kanji Mode): This mode is optimized for encoding Kanji characters, which are logographic characters used in the modern Japanese writing system. This mode allows for efficient storage of Kanji characters in QR Codes.
QR Code (Extended Channel Interpretation): This type allows the encoding of characters from various character sets by using the ECI protocol. It enables the use of different character encodings in a single QR Code.
Structured Append QR Code: This type is used when the data is too large to be encoded in a single QR Code. It allows splitting the data into multiple QR Codes, known as "blocks," and each block contains a part of the information.
Micro QR Code: A smaller version of the standard QR Code, designed for applications where space is limited. Micro QR Codes come in different versions, and each version has a varying number of modules (black squares) to store data.
QR Code with Logo: While not a separate type, QR Codes can be customized by adding logos or images in the center. This is often done for branding purposes, but care must be taken not to interfere with the code's readability.
The choice of QR Code type depends on the type of data you want to encode and the specific requirements of your application.
