A medical identification tag is a small emblem or tag worn on a bracelet,

, or on the clothing bearing a message that the wearer has an important medical condition that might require immediate attention. For emergency medical providers such as paramedics and emergency physicians, medical identification tags are particularly useful in situations where the wearer is unconscious, altered mental status, very young, or otherwise unable to provide critical medical information. The tag is often made out of

with the same information may be used instead of or along with a tag, and a stick-on medical ID tag may be added or used alone. A type of medic identification alert is the USB medical alert tag, essentially a USB flash drive with capacity to store a great deal of emergency information, including contacts and medical conditions. This information is accessible by any computer with a USB port. However, the practical effectiveness of such a system is limited in many cases by medical computer systems that restrict the use of USB devices which may carry malware. It is also possible that a device carried by an unconscious person may not be their own, or not be up to date, with concomitant risks to health and legal liability of medical personnel. Another new type of medic identification alert is QR code based medical alert stickers. The QR code on the sticker links to a web service that contains the individual's emergency information. The information is accessed by any first responder or emergency personnel by scanning the QR code by using a smartphone. In addition to QR codes there are now products that include an embedded RFID chip that allows a first-responder to simply tap their phone against the device. Since a web service is used to store the information there is normally no limitation of how much information that can be stored.

Types

There are various types of medical ID available. The most common form of medical ID is jewelry which provides a logo or inscription indicating a particular medical condition. These medical identification tags can be made out of stainless steel (usually classified as 316L and known as

surgical stainless steel Surgical stainless steel is a grade of stainless steel used in biomedical applications. The most common "surgical steels" are austenitic SAE 316 stainless and martensitic SAE 440, SAE 420, and 17-4 stainless steels. There is no formal definition ...

), sterling silver or gold. If found by emergency personnel the inscription provides an indication of the wearer's special medical needs. Tags are available with pre-engraved conditions or can be custom engraved with your specific medical histories and have the benefit that all information is self-contained and does not require any form of technology to view in case of an emergency. Another type of medical ID jewelry indicates membership in a medical information organization such as the

Foundation, American Medical ID, and StickyJ Medical ID. Such medical ID jewelry includes a member identification number and a toll-free number or URL for medical emergency personnel to obtain full information about the wearer's medical conditions, treatment, and history. These organizations maintain a database of medical information on their members and can provide it to medical personnel when requested. The newest technology allows the user to carry stickers with an

. A similar technology allows the user to carry stickers with a QR code. By scanning the NFC Tag or the QR code with a smartphone, you will reach the stored medical alert information. Modern mobile phones typically have a facility to gain access to the owner's medical emergency information (only) from the lock screen. Silicone bracelets, preprinted with a general medical condition or allergy, are also popular. The lack of personalization may be a deterrent. Recently patients have begun to "tattoo" their medical condition on their wrist or arm, but if the individual's medical condition changes the tattoo would have to change as well. A temporary tattoo might work just as well as a permanent tattoo. Other items include stick on tags that stick onto a driver's license, wallet, or cell phone which are practical for the person who does not want to carry something extra advertising their medical condition. But, in general, emergency medical personnel are trained to look on the patient's wrists for a medical id, and may not look elsewhere. Another type of medical jewelry is a pendant or wrist strap containing a wireless alert button, also known as a panic button, worn in the home as part of a wireless medical alert system. This type of medical jewelry sends a signal to a dialing console which contacts a monitoring service or directly dials first responders when an emergency occurs.
