Why I get the same device ID with my ProximityDevice in Windows Phone

Question

I'm trying to get some info from my credit cards, and I have the impression that the only thing I can get is the NfcAdapter ID.

I'm using this code :

public partial class MainPage
{
    ProximityDevice _proximityDevice = ProximityDevice.GetDefault();

    public MainPage()
    {
        _proximityDevice.DeviceArrived += DeviceArrived;
    }

    private void DeviceArrived(ProximityDevice proximityDevice)
    {
        Deployment.Current.Dispatcher.BeginInvoke(() => Debug.WriteLine(proximityDevice.DeviceId));
    }

Even if I try another credit card, I always get the same info :

\\?\SWD#Nfp#NfcAdapter#{fb3842cd-9e2a-4f83-8fcc-4b0761139ae9}

I have 2 questions :

1- Why I get the same info everytime ?

2- Is there a way to get other infos in my credit cards ?

UPDATE

I have a Nokia Lumia 930

You get the same information each time because the proximityDevice represents the hardware inside your phone; it does not represent the card. It should actually be the same as _proximityDevice.

So how can I get the info from the credit card and not the hardware inside my phone ? – Wassim AZIRAR Feb 09 '15 at 10:15
The link above from @Kulasangar explains why. – Peter Torr - MSFT Feb 09 '15 at 16:06
