The UUID thing I think is a non-issue... RFIDs are already in passports, credit cards, student IDs, etc. Having a UUID on the RFID that is associated with a secure database seems like it would solve this problem.

Then the problem becomes, how do you get doctors and hospitals to use something like this? Creating a private database that providers could optionally use seems doable. The hard part would be creating a large enough percentage of adoption at first. After that, more and more providers would see the benefit of using the system, and patients might even start asking for it, or preferring hospitals that have it.
