Privacy-friendly contact without a phone number
Less exposure, more control.
A controlled contact layer is safer than putting a personal number on a public sticker, sign or device.
Lower exposure
A QR form keeps permanent contact details off public stickers, notes and signs.
More control
You can change notification channels and respond to abuse more easily than with a public number.
Clear context
A short instruction next to the QR code explains why someone should scan it.
