I am perfectly healthy and take no medications. Why would I need a system like this?
Actually, there are situations where emergency medical personnel are not able to provide potentially life-saving treatments unless they know that the patient is on no medication. One such example is a clot dissolving treatment for stroke, which cannot be administered blindly without confirmation that the patient is not on contraindicated drugs (ones that could cause complications). In such a case, the assurance that the patient is on no medications is of critical benefit, as every moment without oxygen reaching the brain leads to irreversible damage and lifelong disability.
