My phone has a copy of my Medicare card. Surprisingly, when you show up to the ER or Trauma Center with broken appendages, they don't ask for ID or your medical insurance. They didn't look for Road ID either. Of course 2 out of 2 is just an anecdote. I carry two Jacksons and two Ben Franklins on most rides and a credit card on long rides. Unlocked phone to call next of kin.
