The problem with a big printed number
A phone number displayed on your dashboard can be harvested by anyone walking past — a common source of spam and scam calls.
A QR keeps the number out of plain sight; only someone who actually needs to reach you scans it to call or text. It's not full anonymity (scanning reveals the number), but it clearly cuts indiscriminate collection.
Phone QR vs SMS QR
Phone QR: scanning opens the dialer immediately — best for urgent move-your-car requests. In 'Create QR', choose the 'Phone' type and enter the number.
SMS QR: scanning opens a message screen pre-filled with text like 'Could you please move your car?'. It's lower-pressure for the sender and leaves a record. Choose the 'SMS' type and set the number plus a default message.
Creating and placing it
Download the PNG, print around A6–A5 size, add a line like 'Scan to reach me', and place it on the dashboard. Laminate against sunlight, but avoid high-gloss finishes that cause glare.
Behind windshield glass, reflections can block scanning — test from outside the glass before settling on a spot.
Privacy tips
If exposing your real number worries you, put a virtual/alias number (carrier or app service) in the QR instead — if it changes, just regenerate the QR.
Generation happens entirely in your browser; the number you enter is never sent to or stored on this site's servers.
