My Rode ID is on my wrist as long as I'm on the bike. Period! On the tag I have:

• my name / year of birth
• city of residence (there may be more people with my name)
• wife's phone number
• daughter's phone number
• See JV-PM Hx in iPhone Notes app

The last line tells the first responders where all my medical information is located and to take the phone with them. I don't lock my phone so they won't be needing a passcode to get to the information. In my phone's Notes app, I have a complete medical history including residence info, medical info, medications and allergies, doctor's names and contacts and insurance info. My phone sits on my aerobars so it's not like they have to search for it.

I can tell you this, as a retired paramedic, it's not a good idea to carry your ID and medical info in a wallet stuck in your jersey pocket unless others riding with you know to tell the first responders where it's located. It's even a worse idea to put your wallet in your saddle bag because no one will bother looking for it. If you are unresponsive, the first responders primary purpose is to get you to the hospital in the shortest time possible and not to look for your identification. Jerseys are cut off and left on the scene and first responders will not take the time to go looking for a wallet in this situation. You will be admitted as a John Doe until someone on the scene finds the wallet and gives it to law enforcement to take to the ER. Unfortunately, at times, it may be too late; especially where allergies to medications are concerned. If you don't carry a smart phone on your rides then get the Road ID with the 800 number on it so they can call the number and get all your medical history. Of course, if your responsive after a crash, all this is a moot point since you can give them the information yourself. But still carry a RoadID.
