I'm trying to access a Smart-card. You know those plastic cards :-)
I've got specs that tell me how determine what type of card I've got (T0 or
T1), and it seems to work on a SLE4428 -card. But my Bank-card (Rabobank,
the Netherlands) does not respond to it.
I've got the specs for a SLE4418 / SLE4428 card that tells me "Reset and
Answer-to-reset", but not what the 32-bit result means (IF it means
anything at all ..).
Does anyone know more about this subject ? Does anyone have sample-data
(what goes in, what *should* come out ..)
Does anyone have a PIC-oriented project (going or finished) that I could
use to get me on-the-road ?
By the way:
I've found several sites that describe (simple) interfaces to the serial
port, but they are none-to-clear about which software works for their

The 32-bit result does not mean anything at all,
it just IDs the type of IC that is on the smartcard.

After the 32-bit ATR, anything goes.
The protocol can be totally proprietary or even I2C
like those Xicor devices (X76Fxxx).
I've designed a simple self-powered serial to smartcard
interface. All you need is a MAX2323, a 74HC05, a couple
transistors and passive components.
It works well for smartcard that does not consume
more than 5mA (most of them don't, anyway).
The software are simple bit-banging on the

could you tell me please the schematic and the software for it? I need to
read exactly that serial from smart card which may be proprietary...

Hi Dr Imre,
I will dig out the schematic and post it on
the list tomorrow as I got the original design
from the Web anyway.
But I can't give you the software as I developed
it for my company. But it's pretty easy to
toggle the RS232 signals, even from Win32 apps.
