There may well be an alternative and possibly quicker answer to this overall over complicated debate.
I assume this device is mainly targeted at people with a known medical problem or problems?
Well if it is I have a Unique Hospital number which the NHS can input into their DB and all my known medical history address next of kin e.t.c. will be revealed. Would this not be a simple solution in carrying your Hospital number on a pendant of some sort officially recognized by the NHS.
N.B. Don't forget to carry your Donor Card [smiley=thumbsup.gif]
