QR codes are tremendously useful because they can store a lot of information in a small matrix of dots, and therefore, are found more and more around us in our daily lives: public transport, food, events, festivals, digital certificates, among others. With an application to read them as QR Code Reader, you can make your phone interpret it, using it to download applications, find locations, or have access permission to a web service, among many other utilities.
QR Code Reader is one of the fastest barcode and QR code readers on the market.
The functions of the app are not limited to reading or interpreting QR codes, which is its main function. It has others such as its ability to read barcodes (more common than the previous ones) and even a built-in flashlight that in situations of poor visibility will help the app to do its job properly.
How does it work? It is very simple. After installing the app, simply give it permission to use the camera of the device and point it at the QR or barcode. Then, depending on its content, the app will either open the information directly or send you to a browser to open the website or download the file it contains.
