Re: Get Response in one step

wumindejia wrote:you can send command of the "get response",the format of the command is 00C00000XX,XX is length.



Thanks for your help, wumindejia.

But what can I do to avoid this way(2 steps) to get response? I want to get the response at once(1 step).

Get Response in one step

Sometimes when I sent an APDU command to card, it responded 61 XX which meant there were a response with XX length and I should send another APDU command to get it.

My question is, how can I get the response immediately? Or how can I get it by one step? Thanks a lot for any help.

Searching for a cheaper card

We have some experience with JCOP OS cards. But I want to find a cheaper variants now. We only need the card to support RSA and the EEPROM 20K is enough. Is there any cheaper cards for my requirement? Thanks

Q with eJava Token

Hello,

I am interested in eJava Token.

But I'm still a bit confused about this product. Should I also need to buy one special card to work with this token?

Or can I use it directly?

Thanks!

why SELECT method should be in the applet

I am a bit confused about SELECT and DESELECT method. AWAK, we can select the applet in the applet itself. Actually, the JCRE is the one who perform applet selection. Thus I think that the implementation of SELECT should be in the JCRE. Am I right? I really want to know why SELECT method should be i...
