The article shows the history of the development of badges as an image accessory designed to represent and/or identify people at a service checkpoint, in a conference or other mass event related to a meeting and contacts of people. This story covers: simple badge cards with printed information about a person, electronic badges with scrolling text, badges with controlled display of QR codes and graphic portraits of people who carry these badges, smart identification and contact control badges. At the same time, it is noted that the latest ideas in the development of badges support the technical side of the creation of “Electronic Citizen” and, while not entirely perfect, are focused on more local use. One of the alternative solutions is the use of color animated biometric QR codes that store facial biometric information about a particular person - his color graphic portrait, QR codes with documentary and biometric information about him.
