How to program PROXY-CARD MATRIX?

Question

Programming

How is this contactless reader programmed?

Answer 1

You've already been told. You need to find out the format of the cards and read what and how they are programmed.
And you throw a photo of the READER, not the programmer.
But I'll google it for you.
1. Find your reader, for example here https://ipro-gsm.ru/internet-magazin-2/product/bes...
2. Read the technical description "Product
purpose Designed for use in access control systems as a contactless card reader Proximity of the Em Marin and Hid standard and conversion of the code of the read card into the Dallas TM and Wiegand 26 code."
We understand that he can work with Em Marin cards (another commercial name for a manufacturer that produces different types of contactless cards and key fobs), all of which actually use the RFID format
Read details about Em Marin ( https://ru.wikipedia.org/wiki/EM-4100 ) and RFID.
For programming - you can buy programmable cards and look for Chinese programmers for 1500 rubles, or original ones for 20,000 rubles. For example here https://proxrfid.ru/em-marine.html

Answer 2

Yes, it seems like it is not programmed. It's just a reader that reads data from the card and sends it to the controller.

Answer 3

You are doing absolutely wrong. You need to learn the language.
Example: jsfiddle.net/IonDen/4j8Lyz71

<select id="test">
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
</select>
Новая цена: <span id="price">1</span>

var $select = $('#test'); // сохраняем в переменную ссылку на селект
var $price = $('#price'); // сохраняем в переменную ссылку на блок с ценой

// на селект навешиваем слушатель, который следит за изменениями
$select.on('change', function () {
    var value = $(this).prop('value'); // если что-то изменилось, получаем value селекта
    $price.html(value); // ставим этот value в поле с ценой
});

Answer 4

$('.offer_list').on('change', function() {
    $(".newprice").html( $(this).find(":selected").val() );
});
