Re: Cached PIN in JavaCard

Are you sure you want to do One time PIN?
"One time PIN" sounds like you are talking about an OTP (one time password). Generating these is a complex problem.

Re: Le field

If you don't know how many bytes you will receive in the response, you can set Le to 00.

FingerPrint demo

I would like very much to test this FingerPrint demo. Is it possible to share the source code for the tool? Or if not, is it for sale and if so what is the cost for this? Thanks.

Re: JCOP card chip speed

As far as I know, there is no method to get these similar information from the card.
The chip speed is something that is not generally exposed.

Thanks for your reply.

In fact, I would like to get some Mifare card with 7 bytes UID. Do you have this kind of card?
