How they differ from static codes, suitable print sizes, analytics and data-protection considerations.
The analysis of the results from dynamic QR codes is conducted by evaluating metrics such as scans, location data, and user behavior. These data can be captured and analyzed using specialized software tools. The obtained...
Read answerDynamic QR codes do not require regular updates as long as the underlying URL or the information they point to remains current. They offer the advantage of being able to change the target address at any time without havi...
Read answerA QR code stores characters as a black-and-white pattern of square modules. The three large squares in the corners serve for alignment, allowing it to be read even when tilted or rotated. Built-in error correction ensure...
Read answerA static QR code contains the target directly in the pattern – once printed, it cannot be changed. A dynamic QR code, on the other hand, contains a short redirect address. The actual target is located on a server and can...
Read answerAs a rule of thumb: the width of the code should be about one-tenth of the reading distance. At a distance of 30 centimeters, this means about 3 centimeters; at 3 meters, about 30 centimeters. Additionally, there should...
Read answerYes, if the evaluation is set up correctly. Scanning a dynamic code triggers a server request, which involves the IP address – and this is generally considered personal data. The use is permissible if there is a legal ba...
Read answerFor everything that doesn't fit on the packaging: detailed product information, user manuals, spare parts, disposal instructions, and reordering. Dynamic codes are almost always the right choice here, as packaging can be...
Read answerWith a static QR code that contains the network name, encryption type, and password. Devices connect automatically after scanning without typing. Important: Guests should be on a separate guest network – a code that lead...
Read answerA fast, mobile, and accessible HTTPS page that directly displays the promised information or action without detours is suitable. For WCAG 2.2 at Level AA, the content should wrap at 320 CSS pixels in width; actionable ta...
Read answerWhen a campaign ends, the QR code can either be deactivated or remain active, depending on the company's goals. With dynamic QR codes, there is the option to change the target URL or delete the code without needing to ch...
Read answerYes, it is possible to collect QR statistics without the use of cookies. Instead, alternative methods such as server-side analytics or the use of anonymized IP addresses can be employed. These approaches allow for the co...
Read answerA QR landing page requires consent for tracking when personal data is processed that allows conclusions about the behavior or identity of users. This is particularly the case when cookies or similar technologies are used...
Read answerQR codes can be used to label branches, posters, or batches by embedding specific information in each code that refers to the respective unit. This includes creating individual QR codes linked to a URL or a database to r...
Read answerUTM parameters are crucial for tracking the performance of QR campaigns. They allow for the identification of the source, medium, and campaign in web analytics. To use UTM parameters correctly, they should be appended to...
Read answerDuplicate scans in evaluations can be prevented through various methods. A common practice is to implement unique identifiers assigned to each scan. Additionally, a database check can be performed to identify already rec...
Read answerYes, QR codes can be both time-limited and password protected. The time limitation is implemented through the programming of the QR code, so it no longer works after a certain period. Password protection is achieved by l...
Read answerA QR code can be configured to call a URL upon scanning that detects the user's language and displays the corresponding language version of the website. This is often done by using browser or device settings that determi...
Read answerA QR code can refer directly to specific content within an app by using URL schemes or deep links. These links are typically designed to open the app when the QR code is scanned and navigate the user to the desired locat...
Read answerQR codes, Data Matrix, and barcodes are different types of machine-readable codes used for identification and data storage. Barcodes are one-dimensional and store information in vertical lines, while QR codes and Data Ma...
Read answerThe GS1 Digital Link is a standard that allows for the provision of digital information about products and services through a single code, such as a QR code. It is needed to ensure interoperability between different syst...
Read answerQR codes play a central role in the digital product pass as they provide a simple and efficient way to deliver digital information about products. By scanning a QR code, consumers and businesses can quickly access releva...
Read answerFor printed materials, error correction level 2 is generally sensible. This level allows for moderate error correction, ensuring that minor errors in the data are detected and corrected without compromising the efficienc...
Read answerHigh color contrasts between the code and the background are crucial for the reliable readability of QR codes. Ideally, the QR code should be placed in a dark color, such as black, on a light background, such as white. A...
Read answerQR codes can work on curved or reflective surfaces, but readability depends on various factors. Curvature or reflection can impair a QR code scanner's ability to correctly scan the information. A clear line of sight and...
Read answerDetecting a covered-up QR code can be done through visual inspection and technical methods. First, the QR code should be examined for signs of damage or irregularities, such as edges that do not finish cleanly. Technical...
Read answerYes, a QR redirect domain typically requires its own TLS certificate to ensure a secure HTTPS connection. This is important to protect the integrity and confidentiality of the data transmitted through the domain. A TLS c...
Read answerYes, it is possible to combine multiple target rules such as language, device, and location. This combination allows for a more precise targeting of the audience and improves the user experience. By using multiple criter...
Read answerManaging thousands of QR codes requires a structured system that considers teams and roles. First, clear responsibilities should be defined to ensure that each group knows its specific tasks. A central platform for creat...
Read answerThe export of QR code targets and scan data typically occurs through the management interface of the QR code software used. First, the desired QR codes must be selected. Then, an export function can be utilized to provid...
Read answerThe deletion or anonymization of QR scan data should be carried out in accordance with the provisions of the General Data Protection Regulation (GDPR). It must be ensured that personal data is deleted immediately when th...
