Holotag

Holotags or  dog tags are a form of military identification.

Background
Pre-War military identification tags used by the United States Armed Forces and its various branches. They consist of two rectangular metal tags with rounded edges, worn on a ball chain around the neck, with a rubber covering on the edges. Personal information is printed on the front of each tag, with a fine print on the back and a holographic image embedded in the tag itself, to facilitate casualty identification for medical and burial purposes. The information includes the soldier's full name, signature, identification number, blood type, security clearance, expiration date, base of operations, and a slogan ''You think you can take me? You go right ahead.'' printed below an identification barcode.
