Dear 涛 梁, all of the commands for MIFARE DESFire are available in the full datasheet, this document is under NDA (Non-Disclosure Agreement) if you have not signed an NDA please contact your closest certified distributor in order to sign one if you already have it, please create an account in Docstore and request full access to the DESFire Family using your NDA number. this devices have two data sheets the short and the full, in the short one you might not get an explanation of all the commands also depending on what you need you might found examples.
if you have any question please let me know.
Have a great day !!
BR
Jonathan
