    Other apps that use QR Code

    WhatsApp, however, is not the only application that uses technology to speed up the search process for users. We list other examples below.


    Instagram has a feature called Name Tag, which is nothing more than a code that, when scanned, allows you to find the person's profile. You can customize yours with selfie, emoji or colored background.

    The feature can be found by tapping on your profile picture in the bottom right corner of your screen. Then, access the icon formed by three lines at the top right and, in the menu that opens, go to Name Tag. In this item, you can either view, edit and scan your own tag or read other people's tags.


    TikTok users can use TikCode, a personal QR code that features the app's logo and the user's photo. You can save the code on your device to send it to anyone you want and scan it to add your friends.

    Find your TikCode or add your friend's at Eu and then on the little doll with the + icon at the top of the page on the left. Then go to the icon in the upper right corner, which refers to scanning. So, scan someone's code or access yours at My TikCode.


    Snapchat was one of the first apps to use QR code scanning as a way to add other users. Your Snapcode is easily found in the user section. Just tap on the profile picture in the upper left corner of the screen.

    To add someone using the code, go to the doll icon with the + icon. Then, go to the app icon located in the search bar and look for the desired Snapcode in the app's image gallery.

    After all, what is a QR code?

    QR Code is a shortened version of the term Quick Reponse Code, which, in free translation, means quick response code. This two-dimensional code (with horizontal and vertical reading) is capable of storing different types of data.

    This information can be accessed using their own reading apps or just the cell phone camera, in the case of more modern devices. The technology stands out for allowing reading even with up to 30% of the surface damaged. It also has more memory capacity than the normal barcode.

    As a rule, a QR code has no defined validity. That is, it does not expire. What can happen is that servers or code generators act in bad faith, not directing the user to their information directly.

    Some of these services send whoever scans the code to the site itself and, after a few seconds, forward it to the desired content. After a while, these generators end the redirect, releasing it only upon payment.

    In other words, the code is still working. However, the targeting created by the service that prevents users from reaching your website, profile, document, etc.
