Re: Get Response 6F00

A40cr cards

I 'm ready to to buy some A40CR cards. And I have visited several shops to compare the price. The price of A40CR in one online-shop is about $7.50, but in your store is $2.00. Is the card you sell exactly same as the cards other shops sell? Is the function of your card reduced or something else?

what was the SW of the installation of the applet? I think your applet has not succesfully installed/registered. This could be the reason why it can not be selected (SW_APPLET_SELECT_FAILED = 0x6999) The SW of the installation of the applet is "90 00", which means the applet has been inst...
