@Dashrender I'm a 3rd party to the end customer here. Acting as the middle man as the customer's IT department wanted to engage outside support to try and vet different products.
I candidly told the customer that while this product will work, it won't work with all of the features they want without some substantial changes to their infrastructure and that the support (at least from this vendor) is pretty awful.
The simple approach here is to not integrate RFID/HID's to the system and simply use the AD Integration with the built-in QR codes that each member is assigned.
Just because something may be supported, doesn't imply that it is support.
Except in this case the vendor very clearly has stated they support you adding custom attributes within AD.
