Navigation. In museums, shopping malls and exhibition halls, QR codes help visitors get information about routes, exhibits or event schedules.
Electronic business cards. Paper business cards require a lot of resources and are often lost or end up among unnecessary things. A more effective tool is a code that will provide access to all the necessary information about a company or person: contact information, links to the site and other important resources.

Depending on the task being solved and the type of information, QR codes are divided into three types: static, dynamic and micro.
Static QR codes
These codes contain fixed information that cannot be changed once created. They always lead to the same link every time they are crawled. If the URL of the page changes, the code will stop working and a new one will be needed.
Static codes are used to transmit permanent information such as page links, contact details, product information, discount messages and individual offers.
Dynamic QR codes
These codes are used for short links up to 20 characters. When scanning, the user gets to an intermediate site, where the system processes the data and redirects him to the desired page.
The advantage of such QR codes is that the information can be changed without re-creating the code. This is convenient for advertising campaigns when you need to quickly change the landing page.
Micro QR codes
Micro QR is a smaller version of standard QR codes, ranging in size from 11×11 to 17×17 cells, containing up to 35 characters. They are ideal for transmitting small amounts of information.

Pros and Cons of Using QR Codes
Pros
Fast and accurate. Scanning takes seconds and eliminates the need to manually enter the link. This reduces the likelihood of error.
Convenience. Any data can be “sewn” into QR codes: from links to contacts and promo codes.
Cost-effectiveness. Using codes in advertising or packaging allows you to reduce the cost of printing additional data.
Traceability: UTM tags allow companies to track crawl statistics and evaluate campaign performance.
Cons
Inconvenient for mobile users. If the QR code is placed on a website that you open from a mobile device, it is difficult to scan - the user will have to look for workarounds.
Dependence on scanning conditions. Poor lighting, low contrast or small code size may make it difficult to read.
Internet required. Most codes lead to online resources, which requires an internet connection. This can be a problem in areas with poor connectivity.
Security: Users may not trust such codes for fear of being directed to malicious sites or phishing pages.
