Go there - I don’t know where


    Once I found behind the windshield in my wife’s car a form for the phone number, which you can see in the photo above. My question jumped up: why is there a form, but no phone number? To which a brilliant answer was received: so that no one would find out my number. Hmmm ... "My phone is zero-zero-zero, and don’t think it’s a password."

    Women are sometimes not very logical in their actions, but with their spontaneous act they can lead to something interesting.


    I vividly imagined a man scrubbing ice from the windshield of her car in winter to get to the phone number on the form and get through, now he’s already at his target and ...

    "Saw, Shura, saw. It is golden."

    Having learned this interesting thing, I began to think how to make sure that she was calm and that the family budget was not affected by punctured tires and broken mirrors.

    At first I came up with the idea that you can take the BLE beacons, which I have some. Such as in this article of mine .

    Here they are in the photo:


    One could make an application that would notice that it was running near a lighthouse with a certain number. This number would correspond to identification data that would be stored on the server and used to call the owner so that the caller could not see this information. That is, a phone number, email address or account in a social network or messenger would not be displayed at all when called.

    I even managed to persuade the respected Ktator to do this . Some prototype was even made. But then the oncoming wave of routine washed away all these dubious undertakings.

    After a year or so, I talked about this idea to a reputable webhamster . In general, he liked the idea, perhaps the service people need. But he criticized the path of its realization to the nines. He said that I was trying to pull my beacons by the ears to the task, which is solved in a simpler way. He told it so beautifully that I believed.

    And he offered the usual QR code. Here is one:


    Then webhamster sawed off the prototype of the secure call service - qrcall.org . Here you can try out the service.

    After registration, you need to print a sticker with a QR code and stick it on the object of your movable or immovable property outside or inside behind the glass so that the QR code can be scanned with a mobile phone. Then any. whoever is nearby will be able to call you via the QR code using the methods you specified using your smartphone. In this case, your personal data will remain confidential.

    If the service will be needed by people, the publication will continue the respected webhamster . Therefore, subscribe to it. And I will continue my usual topics: navigation, the Internet of things and radio .

    We strongly hope for a lively response and criticism of professionals and users.

    Many thanks!
