Use Case

  • You want to use PC/SC to interact with ISO 14443-4 cards.
  • You don't need to control reader feedback (e.g. LED and beeper).

Implementation overview

What is PC/SC?

PC/SCcall_made is a standardized, vendor-independent software interface. You can use it to exchange APDUs (application protocol data units) call_made with ISO 14443-4 cards.

How it works

  • To activate the PC/SC interface on the reader, deploy the configuration provided by us.
  • The reader acts as a pass-through and doesn't intervene in the communication with the card. It directly forwards your commands to the card and all card responses back to the host.

Supported interfaces

  • USB only (access by Windows Terminal Server via RDP possible)


Use APDU via VHL if:

  • You want to control reader feedback (e.g. LED and beeper) via the host.
  • You want options to narrow down card selection to one or more card types.

Your workflow

Activate PC/SC

To activate PC/SC on the reader, deploy the configuration below. With this configuration, BALTECH USB readers implement the CCID protocolcall_made. Linux, macOS, and Windows have their own CCID drivers, which then provide the readers as PC/SC devices.

USB HID always remains active in parallel as a support interface. You can use it to access the readers with our GUI tools, e.g. to update the reader firmware.
