Your camera may automatically scan them. More manufacturers have included QR scanners straight into the default camera app as QR codes have grown more widespread. Many Android phones' internal cameras seek for a typical QR code with a white backdrop and black data points/eyes. A QR code with data points that are lighter than the background will be ignored by some Android internal cameras. (for example, white on black, light blue on dark blue, and so on.)
If you want to give it a shot, here's how to do it: Scan the QR codes above using your phone's camera. Simply open the camera and point it at the QR code above. If your camera supports it by default, a little link to Lê Mai Viet Nam webpage will appear on the screen. If not, you'll need to download a QR code scanner app.
