uwp智能卡提取用户信息

我正在构建一个UWP应用程序,我的目标很简单。我的电脑与智能卡读卡器相连,因此在运行应用程序后,我希望用户将其智能卡插入智能卡读卡器,然后我希望我的应用程序提取他们的所有信息(即:名字、姓氏、地址和其他类似信息),以便 自动填写表单 这样他们就可以很容易地注册到我的服务中,而不必在每个文本框中填写他们的所有信息。

到目前为止我所尝试的

protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);
        string selector = SmartCardReader.GetDeviceSelector();
        DeviceInformationCollection devices =
            await DeviceInformation.FindAllAsync(selector);
        var dialog = new MessageDialog("Number of devices : " + devices.Count.ToString());
        await dialog.ShowAsync();
        var device = devices[0];
        SmartCardReader reader =
            await SmartCardReader.FromIdAsync(device.Id);
        IReadOnlyList<SmartCard> cards =
            await reader.FindAllCardsAsync();
        var dialog2 = new MessageDialog("Number of cards in this device : " + cards.Count.ToString());
        await dialog2.ShowAsync();

        var card = cards[0];
        using (var conn = await card.ConnectAsync())
        {
            // after establishing connection, how can I extract the user information out of their smart cards?   
            var answer=await card.GetAnswerToResetAsync();
            // the above line is supposed to give a buffer can that be converted to string to extract out the requied data?
        }
        reader.CardAdded += Reader_CardAdded;
    }

    private void Reader_CardAdded(SmartCardReader sender, CardAddedEventArgs args)
    {
        //args has no method to extract data as well
    }
