- 911ice is a free service that allows loved ones and medical providers to share life-saving information and support through a virtual waiting room when someone has a medical emergency. - It works by having users add a contact labeled "ICE" (In Case of Emergency) to their mobile device. If an emergency occurs, medical providers can then access the person's critical health information through the ICE contact. - The service aims to improve on traditional emergency response models by facilitating real-time collaboration between various parties through mobile access to a person's medical records and status updates.
