QR Codes Introduction and Key Features – What is a QR Code?

Overview

  • Key Features in a QR Code

Various industries use QR codes, also known as Quick Response codes, to direct users to specific websites or networks, share information, process mobile payments, and store data.

To offer a quick overview of QR codes’ history, in 1994, a Toyota subsidiary developed these codes. Its use is to monitor the production of automobiles and auto components by the corporation. In 2000, it became internationally standardised. Then, by 2002, mobile users in Japan had notably embraced QR codes.

Key Features in QR Codes

How do QR codes work? What information does a QR code contain? Below enumerates the key features of QR codes.

1. Quiet Zone

The quiet zone is the white border of the code. This isolates the code from other printed information.

2. Finder QR Patterns

On the corners of your QR codes are three black and white squares. This easily confirms the shape of the code.

3. Alignment QR Patterns

Alignment patterns make sure the code is readable even if the angle distorts or bends to a curve.

4. Timing QR Patterns

The straight line running vertically and horizontally is the timing pattern. It’s between the three finder patterns, consisting of alternate black and white squares. These lines make it easy to determine the individual data cells within a QR code. Similar to the alignment pattern, this is useful when the view of the code distorts or has damages.

5. Version Information

If you don’t want to hire personnel for round-the-clock security, you can count on the license plate reader to keep watch of everyone coming and going through the parking lot. The data stored in the server will always be available in case of any incidents. 

6. Data Cells

The rest of the black and white squares that are not identified as one of the standard features mentioned contain the actual data of the code.

QR codes work similarly to barcodes. It is machine-scannable and can be instantly read by mobile scanners or smartphone cameras. Scanning the code translates the stored information. The information in the QR code can be numeric, binary, alphanumeric, or in Kanji).

In Qbasis, the use of QR codes to automate processes can be integrated into a business management system. For instance, in visitor management system software, the QR code can be stamped on visitor passes or tickets so the scanner can easily obtain visitor information. Contact us to learn more about how your business can utilize QR codes’ advantages.
