They can be protected with different (AES/DES) keys. Therefore it is most likely you can't just read the data, you need the keys first. You can use a NFC enabled phone and try [NFC Taginfo](https://play.google.com/store/apps/details?id=at.mroland.android.apps.nfctaginfo) to get some information of the card.\r\n\r\n(I will leave this issue open for some time.)"}}
