Why are QR codes more commonly used than one-dimensional codes

The main reasons why QR codes are more commonly used than one-dimensional codes are as follows:

Large information capacity:

QR codes can store more information, including text, images, website addresses, phone numbers, and other types of data. In contrast, one-dimensional codes have a smaller information capacity, typically only able to accommodate information of a few dozen characters, and their content is limited to letters and numbers.

Widely applicable scenarios:

QR codes are widely used in various fields such as product sales, payment methods, electronic business cards, network links, social media sharing, electronic receipts, conference check-in, security verification, etc. due to their high information capacity and powerful encoding capabilities. The demand in these fields has driven the popularization and application of QR codes.

Reading convenience:

With the popularity of smartphones, reading QR codes has become more convenient. Users only need to scan the QR code with their mobile phone camera to quickly obtain information, without the need for specialized scanning devices. And one-dimensional codes require the use of specialized scanners for reading, and the scanner needs to maintain a certain angle and distance from the barcode.

Strong fault tolerance:

QR codes have a certain degree of error correction capability, and even if partially damaged, the original data can be restored through error correction algorithms. This means that even when the QR code image is contaminated or damaged to a certain extent, it can still be correctly recognized. However, one-dimensional codes do not have strong error correction capabilities, and once the barcode is damaged or contaminated, it may become unrecognizable.

Technological development and innovation:

With the advancement and innovation of technology, the generation and recognition technology of QR codes continues to be optimized, resulting in significant improvements in recognition speed, accuracy, and user experience of QR codes. This also provides strong support for the widespread application of QR codes.

In summary, QR codes are more commonly used in daily life than one-dimensional codes due to their advantages such as large information capacity, wide application scenarios, high reading convenience, strong fault tolerance, and technological development and innovation.
