You may remember that in 2014 the badges were credit-card sized. The resemblance goes further in 2016 with an embedded radio-frequency identification (RFID) microchip. This is not only a security measure but also useful as a data-gathering tool for the organisers. You may also notice that about 60 people have photographs on their yellow-edged badges: they are the organisers.
The colour schemes are as before: official delegations and Eurosatory guests have a purple band along the bottom of their badges and the delegation leader’s badge also bears a red dot. A red band indicates the wearer is a VIP, a blue band is a visitor, a green band is an exhibitor and grey is a journalist.
