One issue with QR code on the badge, you train people to allow others to take a close up high resolution picture of their badges. And possibly getting close enough to get the RFID code off the badge so it can be completely cloned. Sounds like a security nightmare to me. Of course, the RFID can probably be read at a distance, but if so, why do the door plates need me to hold the badge right next to them to open the doors?

RFID chips depend on the sensor sending the power for the reply. Low-power sensors require closer contact; high-power sensors can operate from a distance.

Note that the badges are smart cards, not a (comparatively) dumb RFID chip with storage. Thus, they can't really be cloned, anyway.
