THE PROJECT

A scan to connect.
A number kept private.

KnockMe is a digital calling bell built around customer-owned QR codes. A code identifies both its owner and a named context, such as a home, car, bike or wallet, so a visitor can reach the right person without needing their private phone number.

The browser experience connects visitors to the owner’s mobile app. The project combines QR handling, a PHP/MySQL backend, real-time messaging and mobile notifications around a chat-based contact experience.

WHAT IT BRINGS TOGETHER

The moving parts.
One connected experience.

01

Context-specific QR codes

Owners create QR codes associated with identifiable places or belongings, giving each contact request a meaningful context.

02

Browser-to-app contact

A visitor scans a QR code in a browser and connects with the owner through the mobile app’s chat experience.

03

Real-time messaging

The backend and WebSocket services support the exchange of chat messages between the visitor experience and the mobile client.
