SmartCard - Select MF succedd but no response

Question

So I am trying to read my transportation card using what I have learned so far about smartcards.

My ATR is: 3B 6F 00 00 80 5A 0A 07 06 20 04 01 03 01 F4 1F 82 90 00

when I looked in the ATR parser it didn't give me much information.

when I chose the MF file like this: "00 A4 04 00"

I got the response: "90 00"

output: but no data.

How can I go on from here to read files on my card?

Note: [it would be nice if someone can give me a link to a book or guide about smart cards, cause I found nice one about EMV cards but it is not working on all smartcards]

Answer 1

https://www.eftlab.com/knowledge-base/171-atr-list-full/ shows that from your atr, there are similar cards with similar ATR data.

You can try selecting the dedicated file using the offsets below and see what happens;

0x0002 0x0003 0x2000 0x2001 0x2004 0x2010 0x2020 0x202a 0x202b 0x202c 0x202d 0x2030 0x2040 0x2050 0x2069 0x206a 0x20f0 0x2100 0x2101 0x2104 0x2110 0x2120 0x2140 0x2150 0x2169 0x21f0 0x2f10 0x3f04 0xfeff

hope you can continue from there.
