QR codes are everywhere nowadays. We scan them at restaurants to read menus, connect to Wi-Fi at the office, access promotional offers, and many other places.

QR codes can have custom designs, including different colors, backgrounds, and logos. By adding design elements to QR codes, you increase the overall size of the code.

On Android, navigate to the Wi-Fi network’s page to pull up a QR code that your friend can scan on their phone. How do I share my Wi-Fi with another phone?
