Quick in - quick check in.
The concept of using geofencing tools for Telegram mini-applications and chatbots.
Due to the technical limitations of chatbots and mini applications, it is possible to use geofacing tools along with native applications.
Existing technologies, such as: GPS in the background, Bluetooth beacons, Wi-Fi MAC address traps use native mobile OS methods in the background
mode. And they are not suitable for chatbots and mini-applications when the parent application within which they operate is not active.

We created a concept for using geofacing tools based on our own smart beacon technology. This is a unique concept that opens up new horizons for the applicability of mini applications.

The hybrid concept is presented in the form of a fully functional prototype (but is not limited to it), consisting of:

iOS app clips;
mini application "Telegram refueling", emulating the refueling service without leaving the car;
geofencing beacons.

Please note that you need to familiarize yourself with the entire repository for the competition. Including readme file https://github.com/lekontcev-i/Competition-Tg

Quickin prototype.

Screensaver: Video demonstration of the real operation of Smart beacons in a mini application, with the Telegram application inactive, after successfully saving the network to the user's devices - push on a second visit.

Demonstration of the case "Fuel up without leaving the car."

Cool concept. But the mini app technology is not showcased well enough in my opinion.

I think that the column selection should be done inside the mini-app along with the amount and the fuel type. Also scanning the column witht the QR code can be a nice way to enter this information!
