One day, I found a phone number form behind the windshield of my wife's car, as seen in the photo above. I was left wondering: why is there a form but no phone number? The genius answer I received was: so that no one knows my number. Oh well… 'My phone is zero-zero-zero, and don’t think it’s a password.'
Women can sometimes be illogical in their actions, but their spontaneous decisions can lead to something interesting.

I vividly imagined a guy scraping ice off her car's windshield in winter to reach the phone number on that form and call her, and he’s already at his goal and…
‘Saw it, Shura, saw it. It's gold.’
Knowing this interesting fact, I started to think about how to ensure both her peace of mind and that our family budget wouldn’t suffer from flat tires and broken mirrors.
At first, I thought I could use BLE beacons, of which I have a few. Just like in this one of mine .
Here they are in the photo:
It would be possible to create an application that would recognize it was running near a beacon with a specific number. This number would correspond to identification data stored on a server, used to call the owner in such a way that the caller wouldn’t see this information. In other words, the phone number, email address, or social media account would not be displayed during the call.
I even managed to persuade the esteemed . A certain prototype was even made. But then the wave of routine washed away all these questionable endeavors.
After about a year, I told this idea to the esteemed . He generally liked the idea, possibly a service needed by people. But he criticized the implementation approach to shreds. He said I was trying to force my beacons into a task that can be solved more simply. He explained it so beautifully that I believed him.
And he suggested a standard QR code. Like this one:
Then I launched a prototype of the safe calling service — . Here you can try out the service.
After registration, you need to print the sticker with the QR code and affix it to the exterior or interior of your movable or immovable property, so that the QR code can be scanned with a mobile phone. Then anyone nearby can reach you via the QR code using the methods you specified with their smartphone. Meanwhile, your personal data will remain confidential.
If the service is useful to people, the publications will continue to be respected. So please subscribe to it. I will continue with my usual topics: .
We are greatly looking forward to live reactions and feedback from professionals and users.
Thank you very much!
