What's a 2D code?
Quick Reponse Code is a matrix bar code, first run by the Japanese company Denso Wave Innovative. A 2-dimensional code can store more data than traditional 1-dimensional bar codes and support error correction functions, even if partially damaged.
High-quality output
2D code generated using Canvas Rendering to ensure that there is a high degree of clarity at any size, suitable for printing and professional design.
Full platform compatibility
The 2D code generated is consistent with international standards and can be micro-trusted, paid, iOS/Android primary cameras and various types of scans, App. Perfect identification.
It's completely private.
All the generating logic is executed locally in your browser, and your text or URL will not be sent backstage to protect data privacy.
What's the 2D code for?
A 2D code is appropriate for connecting the underline material to a web page or digital content. You can encode the campaign pages, menus, product descriptions, contact details, social home pages or Wi-Fi information into two-dimensional codes and then place it in posters, business cards, tableboards, packaging and mail. The input should be as concise as possible and remain valid after the link is released, otherwise the page that opens will be disabled even if the two-dimensional code itself is identifiable.
2D size, colour and printing suggestions
The screen display and paper printing require different dimensions. The more complex the two-dimensional code, the more intensive the modules, the less able to over-shrew the printing. It is recommended that the dark-coloured outlook be used to fit the light background, that the surrounding blank area be preserved, that the 2-D code not be cut to the edge, and that the low contrast to the background colour not be used. Before official release, scanning was tested at physical distance and light using different mobile phones.
How do you check when the scan fails?
Confirms that the input link can be opened normally, and then checks if the 2D code is stretched, covered, reflected or compressed. If the content is longer, shorter links can be used; If 2D code is printed on packaging or posters, leave-overs should be added and output sizes increased. Download images without changing the width ratio in the layout software and reproducing larger PNGs as necessary.
The difference between static 2D and dynamic 2D
This tool generates static 2D codes, encodes content directly into the pattern and cannot generate a modified image that has been downloaded on this page. When the target address, statistical scan data or validity period is needed, dynamic 2D services with jump management functions are usually used. Either way, target links, privacy policies and access rights should be confirmed before publication.
