Feitian R502 is a composite multi-slot reader.

We change some codes to let support Feitian R502 dual interface reader, The default slot is contact slot.
And the second slot is contactless slot.

Any questions, please mail to [email protected], thanks

Hi How was everything going?

The R502 reader has 3 CCID interfaces:

  • iInterface: R502 Contactless Reader
  • iInterface: R502 Contact Reader
  • iInterface: R502 SAM1 Reader

Your patch make only the first 2 interfaces available at the PC/SC level.
Is it expected?

        It would be great if can support 3 them all.But as I check, it only support two interfaces in  latest CCID driver. Thanks Sent from Mail Master

If the creation of a channel fails then call FreeChannel() instead of
IFDHCloseChannel().
The ressources are unalocated but with no access at the lower layer.

Since the creation failed the channel is not correctly created and
only part of the reader stucture is initialised.

The problem was discovered with the folowing problem:
Program received signal SIGSEGV, Segmentation fault.
