Did the test.

My second-to-most-recent emplyer had NFC/RFID badge cards that
each employee was required to scan at the lobby when entering a
facility.  For the test of one of the metal-lined sleeves, I
asked the "guard" at the desk for permission to test the sleeve
by doing an experiment to see whether the ID badge card could be
read while inside the sleeve.  The "guard" said he would watch
his monitor while I attempted to scan the sleeved badge card.  He
said his system could not see that the badge card existed while
it was in the sleeve.  Outside the sleeve, the badge card worked
perfectly.

Based on that test, it appears that sleeve was sufficient to
sheild at least the type of NFC/RFID used in that badge card.
