Each answer points to the article where the topic is covered in full. ## About the codes ### Do the codes expire? No. A code made by the web part contains the data itself — the link, the contact, the network settings — and works as long as this data is valid. It does not depend on the web part, on the page or on the license: a code that was downloaded or printed keeps working even if the web part is removed. ### Is there a limit on the number of codes or scans? No. You can make any number of codes, and each of them can be scanned any number of times. ### Are the codes static or dynamic? Static. The data is written into the code and cannot be changed after the code is printed. To change where a printed code leads, change what is at the address it contains — for example, update the page behind the link — or print a new code. ### Can I see how many times a code was scanned? No. A static code is read by the phone without any request to the web part, so the scans cannot be counted. To measure interest, encode a link to a page whose visits are counted, such as a SharePoint page with page analytics. ### Is the data that I enter sent anywhere? No. The code is generated in the browser, and the entered data is not sent to Vitextra or to third parties. The data is stored only when a page editor saves it with the page. See [KB10275. Privacy and Security in QR Code Generator: Where Your Data Is Processed and Stored](https://vitextra.com/en/support/kb/10275). ### What can be encoded? Nine types of data: a link, a text, a business card (vCard), Wi-Fi settings, an email, an SMS, a phone number, a location and a calendar event. See [KB10264. QR Code Data Types: URL, Text, vCard, Wi-Fi, Email, SMS, Phone, Location and Event](https://vitextra.com/en/support/kb/10264). ### How much data fits into a code? Technically, up to a few thousand characters. In practice a code stays easy to scan up to a few hundred characters; beyond that the dots become too small for print. See [KB10273. Error Correction and Size: Making QR Codes Reliable to Scan and Print](https://vitextra.com/en/support/kb/10273). ### Does the web part make barcodes of other types? No. The web part makes QR codes only. ### Is an internet connection needed to scan a code? Not to read it. A text, a contact, Wi-Fi settings and an event are taken from the code itself. A connection is needed only for what happens next, for example to open a link. ## About the design and the files ### Can I use the colors and the logo of my company? Yes. The shape and the color of the dots and of the corner markers, the background, a gradient and a logo in the center are all adjustable. See [KB10265. Customizing the QR Code Design: Shape, Colors, Gradient and Corners](https://vitextra.com/en/support/kb/10265) and [KB10266. How to Add a Company Logo to a QR Code](https://vitextra.com/en/support/kb/10266). ### In which formats can I get the code? **PNG**, **JPEG**, **SVG** and **WebP** as a file, and PNG through the clipboard. The size of the image is set from 300 to 4000 pixels. See [KB10268. Downloading and Copying a QR Code: PNG, JPEG, SVG and WebP](https://vitextra.com/en/support/kb/10268). ### Which format is best for print? SVG. It is a vector format and stays sharp at any size. ### Why is my code not read? The usual causes are a low contrast with the background, a logo that is too large and a code that is printed too small. See [KB10276. Why Doesn't My QR Code Scan?](https://vitextra.com/en/support/kb/10276). ## About the web part ### Where does QR Code Generator work? On modern pages of SharePoint Online and in Microsoft Teams, as a channel tab or a personal app. Classic pages and SharePoint Server are not supported. See [KB10274. How to Add QR Code Generator to Microsoft Teams](https://vitextra.com/en/support/kb/10274). ### Is the code that I prepared kept on the page? Yes. Everything that is set up while the page is edited is saved when the page is published, and the visitors see the prepared code. See [KB10269. Publishing a Preconfigured QR Code on a SharePoint Page](https://vitextra.com/en/support/kb/10269). ### Can the visitors of the page change my code? They can change the data and the design in their own browser and download their own codes, but their changes are not saved. Only an editor of the page changes what is published. ### Can the page show the code alone, without the fields? No. The fields and the design sections are always shown next to the code. To show a code alone, download it and insert it into the page with the standard **Image** web part. ### Can several codes be placed on one page? Yes. Add the web part several times; each instance keeps its own data and design. ### Can codes be generated in bulk or from a SharePoint list? No. The web part makes one code at a time from the data entered in its fields and is not connected to lists or other web parts. ### Who can use the web part? Everyone who can open the page can make, copy and download codes. Adding the web part and saving a prepared code requires edit permission on the page. ### Which languages are supported? The interface is available in 50 languages and follows the language of the user. Some labels added in recent versions may be shown in English until their translations are released. ## About installation and licensing ### How is the web part installed? A SharePoint administrator uploads the package to the app catalog once, and the web part becomes available on all sites. See [KB10263. How to Add QR Code Generator to a Page and Create Your First QR Code](https://vitextra.com/en/support/kb/10263). ### Does the installation require the approval of API permissions? No. The package requests no API permissions. ### Is there a trial? Yes. The web part is installed with a trial period. The status of the license is shown in the **About** group of the property pane. ### What happens when the trial ends? The web part shows a notice in place of the generator until a subscription is activated. Codes that were downloaded or printed earlier continue to work. 💡 **Tip** An overview of all capabilities is in [KB10262.
