Information about QR Code
A QR code is a type of 2D barcode consisting of black and white pixels arranged in a specific pattern. QR codes were invented in Japan for tracking the automotive industry during the manufacturing process. Unlike UPC barcodes, QR codes have become more popular and are widely used, often printed or stuck on products and machinery, due to their quick scanning capability and excellent storage capacity for storing multiple information.
QR codes can contain data such as numbers, alphabets, binary, control code, etc. and can encode up to 7,089 characters within a symbol.
There are two types of QR codes: static QR codes and dynamic QR codes, which are created using QR code generating software.
To ensure that a QR code can be scanned, you need to determine two things:
– The size of the QR code
The more information encoded in the QR code, the smaller the dots are. This happens when you create a static QR code. The smaller the dots, the more difficult it is for smartphones to decode. If you have more data to input into the QR code, switch to a dynamic QR code.
– The distance between the QR code and the scanner (usually a smartphone).
The closer the distance between the scanner and the QR code, the faster the data can be read and displayed. If the distance is too far, the scanning time will be longer, and if it is too far, the device may not recognize and read the encrypted information of the QR code.
