One day, I found behind the windshield in my wife's car a form for a phone number, which you can see in the photo above. A question jumped up in my mind: why is there a form, but no phone number? To which a brilliant answer was received: so that no one would know my number. M-yes ... "My phone is zero-zero-zero, and do not think that this is a password."
Women are sometimes not very logical in their actions, but with their spontaneous act they can lead to something interesting.
Emotions
I vividly imagined a man scraping ice from the windshield of her car in winter in order to get to the phone number on the form and get through, now he is already on target and ...
“Saw, Shura, saw. She's golden."
Having learned this interesting thing, I began to think about how to make sure that she was calm, and the family budget did not suffer from punctured tires and broken mirrors.
At first, I thought that I could take BLE beacons, which I have some of. Such as in this mine .
Here they are in the photo:
It would be possible to make an application that would notice that it is running near a beacon with a certain number. This number would correspond to identification data that would be stored on the server and would be used to call the owner so that the caller could not see this information. That is, the phone number, email address or account in the social network or messenger would not be displayed in any way when called.
I even managed to persuade the respected . A prototype was even made. But then the oncoming wave of routine washed away all these dubious undertakings.
After a year or so, I spoke about this idea to a respected . In general, he liked the idea, perhaps the service people needed. But he criticized the way of its implementation to smithereens. He said that I was trying to draw my beacons by the ears to a problem that could be solved in a simpler way. He told it so beautifully that I believed it.
And offered a regular QR code. Here's one:
Then filed a prototype of the secure call service - . Here you can try the service.
After registration, you need to print a sticker with a QR code and stick it on your movable or immovable property outside or inside behind the glass so that the QR code can be scanned by a mobile phone. Then anyone. who will be nearby will be able to call you by the QR code in the ways you specified using a smartphone. In this case, your personal data will remain confidential.
If people need the service, publications will be continued by the respected . So subscribe to it. And I will continue my usual topics: .
We strongly hope for a lively reaction and criticism from professionals and users.
Thank you!
