find why this ERROR i am getting...becoz all the files in smart card are
personalised properly and SC reader is working fine( NEW ONE)..Can
Anybody give some kind Guidance on Same....
I'm not exactly sure what you are doing. are you using some 3rd party
software to access that smart card reader, or are you writing software
from scratch on your own?
I don't know much about serial smart card reader, and in our project
for smart card reader drivers (OpenCT) we don't have a driver for the
ACR 30, only for the usb variant.
so you might be best of asking the manufacturer for a detailed
developers manual on how to use it. Also I can suggest the "smart card
handbook" by rankl/effing, it is a great resource when dealing with such
lower levels. In case you need to use T=1 protocol to talk to the
card/reader, OpenCT has an implementation of that, so it might be easier
to add a new driver to openct, than to write something on your own.
note however that OpenCT is under LGPL license.
Right now before sending RESET i am setting PTS of card ( card protocol).
I think the normal way is to RESET, get atr, parse ATR, send PTS get PTS
response, use card. but I could be wrong as well.
And I am not changing SC reader protocol & using Default 9600
baudrate..and in MCU i am setting 9600 baud rate..
that is real slow. for developing it might be ok, but later you will
want a higher speed, so your card transactions are much faster.
Smart card is 4k Altexo schumberger cards...
4k cards? I didn't know those exist, I have some 8k card, and it is
already stone age technology. or maybe you meant 64k card?
also note: cryptoflex or cyberflex? it makes a big difference, as with
cyberflex you need some applet on the card.
