What information I have found of it can be found on the Yale Doormant [url=http://www.yaledoorman.no/no/yale/Yaledoorman/Produkter/?groupId=2489&productId=65467:2tmky4zq]homepage (Norwegian)[/url:2tmky4zq], and their [url=http://www.yalelock.com/en/yale/com/Partner-Area/Yale-Emea-Partner/?groupId=667&productId=65227:2tmky4zq]international page[/url:2tmky4zq].

Does anybody know if the Yale Doorman works with the NFC Ring?
