21st century tech

A very important technological advancement of the 21^st century has got to be the various types of medical IDs. I am studying to be a healthcare professional and I think this advancement has done a lot for society as a whole. Originally there were only medial cards that had your information on them. Today there are various forms of medical IDs. One example would be a medical bracelet. These are bracelets that have your health information inscribed on the bracelet. You can have information such as blood type, allergies, diseases, and even emergency contact numbers. They have a wide range of styles and choices when it comes to the medical bracelets. They even have ones for kids that are made out of plastic and look more like a toy than a medical bracelet. Medical IDs can also come in the form of a watch, necklace, or even cell phone case. I believe that this is just one step to further technological advancements in the future. I think that one day in the future we will not even need to have any form of physical medical ID at all. The medical IDs will be chips in our arms or some other body part. The chips could be scanned by police or other professionals that typically are first responders to emergencies. The chip could hold all of your medical information in order to give the people that are helping you the best idea of how to help you. This would also eliminate the need for people to remember to wear their medical bracelets and they could never lose them because they would be a part of their body. I could definitely see this being an advancement that occurs sometime in the future because technology is progressively getting smaller and more effective as time goes on.
