While having your entire catalog of medical issues on your person at all times would sure come in handy if your GPS leads you into a body of water or you get mangled by a Japanese Land Walker, implanting an RFID data chip underneath your skin could (understandably) sound a bit extreme. While digital medical records and emergency panic buttons are certainly swell, EMI's 911 rCard places every quirk and prior health issue you've ever had onto a single wallet-sized card, which can be viewed immediately by any medical personnel that would need pertinent information statinum. The "vivid, full color LCD" can display everything from medical charts to photos / text describing the patient's history, and sports a built-in battery that can handle "about two hours" of constant viewing before it needs recharging. Boasting USB connectivity, users can continually update and upload new information from their EMI web portal onto the rCard, including any mild injuries sustained during last week's campouts. The 911 rCard is available now for $79.95, which includes a USB cable / charger and the first year of website access, while additional years of data storage and interfacing will run you $20.
