The Technology Behind CarNotify: QR Codes, WhatsApp, and Anonymous Chat Explained
How QR car alert technology works at CarNotify: random tokens, secret activation, email alerts today, and anonymous chat on the alert thread — WhatsApp as a future channel, not a leaked number.
Searches for “how QR WhatsApp car alert technology works” often assume the sticker opens a WhatsApp chat with your personal number. That would be a privacy failure. CarNotify uses a web scan, server-side notify, and optional in-thread chat.
QR and tokens
Each sticker has a long random token in the URL. Shop cards add a scratch secret so a stolen unused pack cannot be claimed easily. Failed secrets lock out.
Notifications and chat
The current release delivers owner alerts primarily by email. WhatsApp and SMS are product directions, not an excuse to print those handles on the car. Chat is scoped to one alert id and a scanner session.

Stop printing your phone number on the car. Create a CarNotify account or activate a shop sticker.
