Support for Bangalore's "Namma Metro" Varshik Card

[the-solipsist]

Thanks for this app, which seems quite useful.

I wonder if it can be extended to the Bangalore metro card ("Varshik"). It is either a MIFARE DESFire EV1 or MIFARE DESFire card. (NXP TagInfo says it is a DESFire card - MF3ICD40, while the MIFARE website state that it is a EV1 card). What information is needed to figure out if it will work?

Here is the output I get after scanning it in Farebot.

Hey. I think I will need physical instance of the card? Can you send me one? I'll pay for the card and shipping
