Scanblip: a private contact channel for parked vehicles

Field notes

The service assigns each vehicle a permanent QR and routes scanner-submitted reasons and messages to the owner by email, without revealing either party’s phone number, name, or email address. Owners can download PNG or SVG files, print the code themselves, pause or replace it, and block visitors. The free tier covers up to five vehicles; a weatherproof sticker is described as planned rather than currently available.
