# Pass Through for MIFARE DESFire

## Command 0x1102 – Pass Through Command for MIFARE DESFire, Type 4

After a MIFARE DESFire Light/EV1/EV2/EV3 Tag is activated, the host uses this command to send commands and receive responses to and from a MIFARE DESFire Tag.

There will be a fixed 30 second timeout for commands that require multiple command/responses.
