Belgium Identity Card feature crashes on IIS W3WP.exe

Question

My registration tool has a feature which allows candidates to load their personal information (like name, address, ..) from an ID.

When I compile the application with the build-in webserver in VS2010, and press the button to load ID information into textboxes, there is no problem. When I publish it on the localhost (with IIS), it crashes when I press the button.

This is what I received in my event viewer:

     0 
   APPCRASH

I'm working on a 64-bit laptop, use the Belgium Identity Card SDK.

Here you can find my code for the button;

        protected void Button1_Click(object sender, EventArgs e)
    {
        //READ eID
        ClearTextBoxes();
        try
        {
            BEID_ReaderSet ReaderSet;
            ReaderSet = BEID_ReaderSet.instance();

            BEID_ReaderContext Reader;
            Reader = ReaderSet.getReader();

            bool bCardPresent = Reader.isCardPresent();

            if (Reader.isCardPresent())
            {
                if (Reader.getCardType() == BEID_CardType.BEID_CARDTYPE_EID
                    || Reader.getCardType() == BEID_CardType.BEID_CARDTYPE_FOREIGNER
                    || Reader.getCardType() == BEID_CardType.BEID_CARDTYPE_KIDS)
                {
                    try
                    {
                        Load_eid(Reader);
                    }
                    catch (Exception ex)
                    {
                        labelEx.Text = ex.Message;
                    }
                }
                else
                {
                    labelEx.Text = "No valid card, please insert a valid IDcard";
                }
            }

            else
            {
                labelEx.Text = "No IDcard found, please insert your card";
            }

            BEID_ReaderSet.releaseSDK();
        }

        catch (BEID_Exception ex)
        {
            BEID_ReaderSet.releaseSDK();
            labelEx.Text = "No valid cardreader found, please connect a valid reader";

        }

        catch (StackOverflowException ex)
        {
            BEID_ReaderSet.releaseSDK();
            labelEx.Text = "Error: " + ex;
        }

        catch (OutOfMemoryException ex)
        {
            BEID_ReaderSet.releaseSDK();
            labelEx.Text = "Error: " + ex;
        }
    }

        private void Load_eid(BEID_ReaderContext Reader)
    {
        try { 
        BEID_EIDCard card;
        card = Reader.getEIDCard();
        if (card.isTestCard())
        {
            card.setAllowTestCard(true);
        }

        BEID_EId doc;
        doc = card.getID();

        txtFirstN.Text = doc.getFirstName();
        txtLastN.Text = doc.getSurname();
        txtDOB.Text = doc.getDateOfBirth();

        //CUT GETSTREET IN STREET AND HOUSENO
        string street= doc.getStreet();
        string[] words = street.Split(' ');

        txtStreet.Text = words[0];
        txtHouseNo.Text = words[1];

        txtPostalCode.Text = doc.getZipCode();
        txtCity.Text = doc.getMunicipality();
        //sText += "Country = " + doc.getCountry() + "\r\n";

        }

        catch (Exception ex)
        {
            BEID_ReaderSet.releaseSDK();
            labelEx.Text = "Error: " + ex;
        }
    }

How can I solve this problem?

Answer 1

Most likely your Application Pool is running under a user which does not have a privilege to access the card reader. This would cause a driver fault which can crash the w3wp.exe process.

Change it to a dedicated user and assign appropriate privileges for this user, or for testing purposes, set it to run under localsys.

Answer 2

Move your code to Javascript (in the browser/html).

I don't think the IIS user has the permission to communicate with the ID reader API.
