-contactless cards have no atr, what is returned by the reader is a fake byte string that looks like an atr and is mostly reader dependent. -the meaningful bit is the application, not the container, this is more and more true with loadable objects, such as javacards and nfc phones. Two objects can have totally different ATRs and still host the exact same application. -some cards have a serial number in the atr, so a simple match will only work for one card. You need a mask, which adds complexity. So if anyone is designing a card recognition application, he should just avoid the atr. The fact that MS did it is not a good reason :) Regards Sebastien _______________________________________________ Muscle mailing list [email protected] http://lists.drizzle.com/mailman/listinfo/muscle
