Re: javacard communication
The unique identifiers for javacard communication? For typeA, the reader identifies cards by uid. For typeB, the reader identifies cards by pupi.
For T0 or T1, it is contact, no need to identify.
Maybe, you can descript your question in detail.

On javacard, the API "APDU.getProtocol()" should help you to find which protocol.
In addition, outside the card, you should be aware of a protocol on BusHound.

Re: a question about smart card reader
For a smart card reader, which protocol do you want to implement? contact or contactless? In my image of a reader, communication between the reader and card is 7816 contact protocol or 14443 contactless protocol. And the communication between reader and PC is CCID protocol. While, if you want anothe...

Re: How to calculate baud rate OR speed of CARD from ETU and ATR ?
First, we must understand several concepts： 1. Clock cycle: T, frequency f = (1/T) 2. Baud rate: how many bits per second can be transmitted 3、1 etu = (Fi/Di)/f So, 1 etu = (Fi/Di)/f = 372 * T baud rate = 1 second / 1 etu = 1 second / ((Fi/Di) * T) = (1 second * f) /(Fi/Di) For example: TA1 = 1, Fi ...

your way is very interesting. But I mean is how to detect attack during the RSA process or after the RSA process.
