It is illegal, you know
? We can't help you, but let me give you some tips: you should find a timestamp on the ticket. Find it, find out how it's calculated, and you're on your way (as long as the part containing the timestamp isn't write-protected).
Once you find the problem, I highly suggest you to report the problem to those concerned by the vulnerability, so that they can fix the problem, and maybe reward you somehow
I have already worked in this very field, it is a rather fascinating one
How can i get this files from my bus card ? i have phone with nfc and rooted. whic program actually thx
I just published an app on here called UltraManager
. If your bus card is a Mifare Ultralight tag, you can use my app for the purpose. Otherwise, there are some good apps on Google Play, just look for "NFC tag reader"
