What are QR Codes?
QR stands for Quick Response. It is a smarter version of the ubiquitous barcode, and was originally developed in Japan for the automotive industry. Machines can read QR codes faster than barcodes, and QR codes can store more data in less space.
If QR codes had stayed inside the factories, we probably wouldn't care, but now they are used for all kinds of things: coffee shop loyalty programs, e-tickets for sports and concerts, "find out more" links on classifieds or packaging, and share contact information.
For most of us, the main reason to use QR codes is to get a web link to find out more information about something or to get a password for a wireless network - scan the code and the information should appear in your web browser or connect to it. net.

All you have to do is switch to Lens mode and point the camera at the QR code you want to scan. On Samsung smartphones, the Bixby Vision app can also be used as a QR code reader.
However, if your phone is neither a Pixel nor a Samsung, you don't have to worry - if you have the Google Assistant you should already have the Lens option. It can be found via the camera icon when the Assistant is in use. If it's not there, you can download the Google Lens app directly from the Play Store.
