Does exist method to call beep inside device when card is attached?

[cuamckuu]

This is part from main.cpp, that might be helpful. It will wait for card to be attached and then calls for beep() function which you can define yourself

        DeviceNFC device;
        std::cerr << "[Info] NFC reader: " << device.get_name() << " opened.\n";

        while (!device.pool_target()) {
            std::cerr << "[Info] Searching card..." << std::endl;
            std::this_thread::sleep_for(std::chrono::seconds(1));
        }
        beep() // Here is your code

error: ‘beep’ was not declared in this scope

You should define that function yourself and make "beep" and other stuff you want there, that's why there is comment
