Hi,
>From looking at the BusinessCard example provided by OCF, the application
compares the ATR response returned by the card to check whether the
application/AppletProxy can support this card. It seems to me that ATR
response can be different from card to card because the ATR returned from my
Cyberflex card is different from the one hard-coded in the sample. Is it
normal in real life that terminal applications always check for a particular
or a list of ATR responses in can support? It doesn't seem practical for me.
Especially in the Internet environment that we might not know what cards
users might be using when accesing our web site (assuming the users have a
reader and OCF for our applets to access the card).
So, in summary, what are you really looking for when checking the ATR
response? Are you indirectly checking whether the card is a JavaCard that
you can use? If so, is there a better way to check beside checking the ATR
response? Or this is a non-issue because there is a standard on ATR response
smartcard can return to indicate what card it is.
thanks and regards...
Sam
