Hello,
in the documentation I've followed the instructions how to check if a card is lf or hf. But after this check there are a plenty of card types left. Is there a good way how to find out what specific type the card is? Are there any standard procedures I can go through?
I'm a newbie in RFID. I'll be happy for any kind of help. Link for HowTos or Docs are nice, too.
Thanks for your help.

You can start by posting a picture of your card (both sides)
And if you can, open it and post a picture of what is inside (chip+antenna)

Ok, thanks.
So there is no way to check the card type by reading raw data samples at look at the plot? Or something similar?

for HF you can try the different Reader functions (hf 14a reader which will attempt to identify a iso14443a chip)
for LF you can do a lf read - data samples 12000 - and then attempt a demodulate depending on what type you suspect it is. if lf indalademod works then it is likely a form of indala (or at least psk encoded). if lf hid demod gives the expected output then it is an hid compatible card.
if all else fails you can do a data plot after data samples and look at the wave form to try to identify the modulation - and/or the repeating bit pattern.
LF cards are usually dumb, as in they don't authenticate or tell the reader what they are. they just spew radio waves when powered.
If you are stumped then you can post your trace or wave plot here for help decoding.
