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.
