Call-Me Codes Explained
A phone call QR code is the simplest code of its kind, since it carries nothing but a phone number. The generator wraps the number in a tel link and encodes it into the pattern. When someone scans the code, their phone recognizes the tel instruction and opens the dialer with the number already entered. On most phones the call does not start on its own; the dialer shows the number and the person taps to confirm. That confirmation prevents accidental calls and keeps the user in control. Because the number lives inside the code, the flow works the instant the camera reads it, with no web page to load. The appeal is friction removal: instead of reading a number off a sign and typing it digit by digit, the scanner reaches a ready to call screen in one step, with no chance of a misdial. If you want people to save your full details instead of calling, the vCard QR Code Generator is the better fit.
