oh that's a shame - that was the major reason I bought the rings!
ah well, not the fault of the rings, just mine for not checking :-)
Thanks for your reply.
If I've been given a door fob from work, is there a way to copy the information on the fob to my ring, so that I can use the ring to open the door?
I don't have access to the underlying data of the access list etc, I just have the fob.
