The only issues that will come into play are if it's a proprietary style of tag with a smart chip in it or if it has more data storage than your ring does. This will no doubt change in future revisions of the ring.
I think the best way to go about it would be to get people excited about the ring, and to emphasise it's usefulness and utility (I can start my car/unlock my door/turn my light on/make a personalised cup of coffee with mine... if we could use these instead of or in addition to the standard swipe cards then people would take better care of them and love and cherish them - you'd spend less on card replacement. )
