Use eID APDU codes with node pcsclite

I need to access the eID information through node. For this I have found a package (https://github.com/santigimeno/node-pcsclite) to do this. The site has an example which seems to work (do something atleast. I have copied the following code :

#!/usr/bin/env node

var pcsc = require('pcsclite');

var pcsc = pcsc();
pcsc.on('reader', function(reader) {    console.log('New reader detected', reader.name);

reader.on('error', function(err) {
    console.log('Error(', this.name, '):', err.message);
});

reader.on('status', function(status) {
    console.log('Status(', this.name, '):', status);
    /* check what has changed */
    var changes = this.state ^ status.state;
    if (changes) {
        if ((changes & this.SCARD_STATE_EMPTY) && (status.state & this.SCARD_STATE_EMPTY)) {
            console.log("card removed");/* card removed */
            reader.disconnect(reader.SCARD_LEAVE_CARD, function(err) {
                if (err) {
                    console.log(err);
                } else {
                    console.log('Disconnected');
                }
            });
        } else if ((changes & this.SCARD_STATE_PRESENT) && (status.state & this.SCARD_STATE_PRESENT)) {
            console.log("card inserted");/* card inserted */
            reader.connect({ share_mode : this.SCARD_SHARE_SHARED }, function(err, protocol) {
                if (err) {
                    console.log(err);
                } else {
                    console.log('Protocol(', reader.name, '):', protocol);
                    console.log('info : ' , reader)
                    reader.transmit(new Buffer([0x00, 0xB0, 0x00, 0x00, 0x20]), 40, protocol, function(err, data) {
                        if (err) {
                            console.log(err);
                        } else {
                            console.log('Data received', data);
                            reader.close();
                            pcsc.close(); 
                        }
                    });
                }
            });
        }
    }
});



reader.on('end', function() {
        console.log('Reader',  this.name, 'removed');
    });
});

    pcsc.on('error', function(err) {
        console.log('PCSC error', err.message);
    });

I then navigate to the directory and use node + "filename" and it gives me the following output :

output

As far as I can tell it is this part (the APDU code):

 reader.transmit(new Buffer([0x00, 0xB0, 0x00, 0x00, 0x20])

that will give me a certain piece of information.

I need some more documentation about all of this, specifically a list of APDU's that I can use; for example the APDU to read the eID picture.

I've searched with every keyword I could think of so far, and haven't found anything useful. Really hope someone can point me in the right direction.

You can read this website to learn more about smart card and how it works. I'm not the expert in this matter but the website helps me a lot.

http://www.cardwerk.com/smartcards/smartcard_standard_ISO7816-4_5_basic_organizations.aspx

"3B 98 13 40 0A A5 03 01 01 01 AD 13 11" is your card ATR which probably is "Belgium Electronic ID card". You can check ATR from this website

https://smartcard-atr.apdu.fr/

To retrieve data from smart card:

  1. Send command APDU contains CLA 1 byte, INS 1 byte, P1 1 byte, P2 1 byte, Lc field, Data field, Le field.
  2. You will get response APDU contains SW1 1 byte and SW2 1 byte. You need to read the manual to understand its meaning.
  3. Then send the get response command to retrieve the data

In you case, 69 is SW1 86 is SW2. The meaning is "Command not allowed (no current EF)"
