Accessing to Smart Card Readers PC/SC with Labview

[Fuquey]

Have anyone try to read the ATM Card / Credit Card before?

[Fuquey]

May I know what is ATR Response and ATR stand for what?

Apple James good day,

I googled your question and I have this information for you:

Peter Tomlnson worte:

"Most of the ATR is concerned with low level features and parameters for the
communication between card and terminal, and these should be handled by the
reader and its device driver in order to decide whether this reader and
driver can properly handle the card offered. As some projects have found,
sometimes the reader and driver have to refer decisions about handling the
card further up the chain, but the decisions should then be handled by a
user intervention layer."

I tried again using same winscard.dll with the functions sCardEstablishContext, sCardConnect, sCardStatus, sCardDisConnect, sCardReleaseContext funtions in the order.

But i can't able to get the ATR value.

Please help me out.

I Googled 0x80100008L and quite a few hits.  You may want to check these out;  Generally, coding in LabVIEW paralells text-based coding, so if you can figure out how to get around that error in C or VB, we can probably help you translate that change to G (LabVIEW).

Dear Champions,

In my application, everything is fine.

1) sCardEstablishContext works fine

2) sCardListReadersA showing correct name of my reader

3) sCardConnectA give proper mode(1) and protocol(1) values

4) sCardStatusA ???????????? There is the problem. It gives state(6 - reset) and protocol(1). That is correct i think. But ATRLEN is 0 and no ATR was received and most of the times labview crashes when the data comes to scardstatus(when i run in highlight execution).

I attached my vi and dll in zip format.

Please do the needful asap

Thanks,

Mathan
