Bogota - Transmilenio

[khoyot3]

I am interested in getting the information off of the mifare cards that We use here in Bogota, Colombia. Right now there are a lot of news about this right now because the municipality in the process of changing the technology.

What is the way to add support to a card into farebot?

Most Mifare Classic cards require an encryption key to read data. You can try using one of the cracking tools (Mfoc).

I already have keys dumps using mfoc and import it in farebot but it show a java.lang.NullPointerException error.

Can you please grab the latest code from git? I fixed a NPE but haven't done a deploy yet.
