From what I've seen, no USB drives allowed in hospital computers(data mining, virus concerns, etc). I know my computer won't even recognize a USB drive if I want to save something to it.

Regarding name, yes, it helps. They can pull up your medical record if you're at the same hospital, police can pull your ID (which has address, which typically has next of kin living there).

If you don't use the SIN up there for medical records, having your health insurance ID would be a legit alternative.
