Default OV-Chipkaart

Hello people,
So I recently was playing around with some NFC apps, and I found out my OV-Chipkaart (Dutch public transit card) was read by my phone. Unfortunately I got a lot of numbers and stuff I didn't understand. Does anybody know more about this?


Phone: Samsung Galaxy Nexus
Root: Unlocked & Rooted by Wugfresh's Galaxy Nexus Root Toolkit v1.4
ROM (testing): ParanoidAndroid 1.9.1Alpha
Kernel: franco.Kernel 4.0.3/4

Vodafone (Libertel)
The Netherlands


I feel like I contribute far too little to this forum. Therefore, if you have ANY questions about my phone, rooting, flashing, or anything related, just PM me. Feel free!!
PM me!


Samsung Jet (S8000) --> HTC HD2 (T8585) (Broken) --> Samsung Galaxy Nexus (i9250) (Current)

The card is encrypted. If you get the key (there are a couple of articles on the internet which tell you how to get it), you should be able to read the entire card. Without the key you can only see the expiration date.
I saw it was possible to add your own MIFARE key in the TagInfo app. The only thing you need to get this key is an RFID-reader for your PC and some processing power (and the appropriate software).

Default UID

Each contactless chip (incuding the Mifare you have) has a unique id which is accessible to any contactless reader, in this case you phone. Unique id enables the reader to overcome collision for reading one chip at a time. This is is probably used as the id of your card by the system it is being used.

i tested it on my personal ov chipkaart but it didn' t work because i haven' t made a dump off the card. i haven' t got a reader for it so maybe if a xda that lives in Rotterdam/Cappele a/d Ijssel is kind enough to make a dump for me

I also recently checked my bus-card and the phone could read some of the info in the card, so i was wondering if it is possible to clone the info in the card to some other nfc tag, which would be cool, and also if i use the phone as rifid reader, mentioned above, connected to pc with usb then theoretically it would be possible to reprogram the card...?
And also another question, is it possible for the phone to send out same info which is on the card so i could use phone instead of bus-card at the bus?
EDIT: I read previous topics and realized that this is impossible.

The ov-chipkaart part is now available and working in the source of github/wandcode/farebot. I have tried and confirmed that this is working. You will need to crack the MiFare classic keys first, this is only possible on a ov-chipkaart by NXP-semiconductors (so not the Infineon version)

I don't have a RFID card reader... Is it possible to dump the chipkaart keys with the Samsung Nexus and then crack the keys with the PC?
