Yes! Yes it they do!

In preparing for a presentation to some peers in the wider IT community tomorrow I have access to some YubiKey Neo authentication keys; in doing some extra reading up on the keys I thought – I wonder if these work with the MIFARE readers (note that these are MIFARE readers not the proprietary Paxton only readers) that are part of our Door Access Control system.

Lone behold they do; in the revision of the keys we have it’s a NXP MIFARE Classic 1k chip.
