Get 6300 when sending APDU to card

Post by Robertdul » Thu Sep 22, 2016 2:04 am

Hi,

I have a java card supporting dual interface(contact and contactless). My applet can work fine on contact interface. But when I connect the card via contactless interface, I send SELECT command to my applet, I got 0x6300. Shall I do anything to contactless interface of the reader in order to let it recognize my card?

Regards&Thanks
Robert

sw=63 00 is a rather uncommon error code. Could it be that the card reader did not detect the card?

Usually if your reader is compatible with PCSC & ISO/IEC 14443, you should be able to communicate with it. You don't need to do anything.
