Ideally, from a tech standpoint, tie it to a smartphone app that can “read” basic-yet-critical medical info from a barcode (e.g. medication allergy, heart condition, diabetes, past concussions, etc.) and display it on the screen without needing an internet connection.
I only have a medication allergy, so that’s the main thing that’s listed on my RoadID… but for someone who say, multiple allergies and other stuff that’s too much to fit on one line, it might be worth having.
