HCE operation

Choosing this mode enables Host-based Card Emulation (HCE).

Bit 4 "expose the cardlet as a virtual card in the PC/SC slot" must be set for HCE operation.

After having enabled HCE using this CONTROL command, a virtual card appears as present in the contactless slot. Invoke the APDU interpreter's HCE POLL, PUSH and CONTROL instructions through SCardTransmit.

NFC Forum type 4 Tag cardlet

This cardlet emulates a NFC Forum T4A Tag.

If bit 4 "expose the cardlet as a virtual card in the PC/SC slot" is set, a virtual card appears as present in the contactless slot. Invoke the APDU interpreter's READ BINARY and UPDATE BINARY instructions through SCardTransmit to access the Tag's content from the host.

If bit 4 is not set, the Tag's content can only be accessed from the NFC interface.

Loopback cardlet

This cardlet is used to test the NFC interface.

Bit 4 "expose the cardlet as a virtual card in the PC/SC slot" must NOT be set with this cardlet.
