QR VS PHONE NUMBER

Both methods help people contact a vehicle owner, but they differ significantly in privacy and control.

The practical comparison

A printed number is instantly readable but permanently exposed. A QR code requires a scan and can be connected to a controlled alert workflow.

The key difference is that QR access can be paused, replaced or monitored.

  • Phone number: simple but public
  • QR alert: private and controllable
  • Phone number: no alert history
  • QR alert: activity can be logged

Which is better for most owners?

For owners who value privacy, a secure QR system is generally the better communication method.

The printed number may still be useful in limited contexts, but it provides less control.
