First of all, we must be clear that it is a QR code. QR codes are codes that contain information that can be read by a camera, QR codes are two-dimensional, that is, it is necessary for the Vodafone Smart Tab 4G camera to read both the width and the height of the QR code and can contain more information than a barcode (one-dimensional).
QR codes are often used to open a web address from a mobile device such as the Vodafone Smart Tab 4G using its 5 MP camera or if used with a specific application, it can offer information about a product, service or serve to authenticate a user.
On the Smart Tab 4G you may have to download a QR reader or QR scanner app, since the code reader is not included in the camera software.
Estimated time: 2 minutes.
1- First step:
To read or capture a QR code on your Smart Tab 4G you have several options, if your Vodafone Smart Tab 4G has the Play Store application store, look for its icon and click on it.
If, on the other hand, your Vodafone Smart Tab 4G doesn't have a Play Store, see the following article: Google Play alternatives
2- Second step:
At the top of the Play Store application store there is a search engine, click on it and type “QR” or “QR scanner”.
3- Third step:
There are many applications to read or capture QR codes for your Vodafone Smart Tab 4G, we suggest that you choose the application that has the highest number of positive votes. We also recommend that you read the opinions of other users to avoid problems and misunderstandings. Keep in mind that the first results can be ads.
4- Fourth step:
We select one of these applications to scan QR codes from your Vodafone Smart Tab 4G, in this tutorial we have selected as an example an application called “QR & Barcode Scanner” but the operation should be the same in any other application to read QR codes, nowhere If we recommend this particular application, we are not responsible for its use or possible problems it may cause.
5- Fifth step:
Once installed you will see the option “Open”, if you wish you can return to the home screen of your Vodafone Smart Tab 4G, you will have the application icon on this screen, if you cannot find it, drag to the right until you find it. Open the app.
6- Sixth step:
When you open the application for the first time on your Vodafone Smart Tab 4G it will ask for permissions to access the camera, we do not recommend accepting any other permissions that are requested such as access to the location or to Bluetooth since they are not necessary, it is only necessary permission to take photos and record videos.
7- Seventh step:
We point with the Smart Tab 4G camera at the QR code that we want to read, trying to make it appear correctly focused and content within the square that appears on the screen or at least within the viewing space, that is, we cannot bring the camera too close to prevent the code is cut off. The QR code must be able to be seen in its entirety on the screen of the Smart Tab 4G, the code does not have up or down, so it does not matter from which angle we approach it.
8- Eighth step:
Most of the QR codes contain a web address to open from the browser (Chrome, Firefox, Opera, Brave) so the option to open the content of the QR code from the browser should appear, click to open the web page. Most of the free applications for reading QR codes contain advertisements so you may have to close the advertisement or avoid clicking on the wrong link.
With these simple steps we have learned to read QR codes from our Vodafone Smart Tab 4G. Most QR codes are used to open websites, either to see the menu of a restaurant or to access a discount code or offer.
