3GSM - Learning from mistakes
Last year, the 3GSM passes where SIM cards that you had to give when you would enter a hall… that was such a hassle to take ou the pass and put it back in ! This year, they improved by using embedded RFID tags and that was so much better ! Definetly, RFID is the turnkey solution for identication (Hong Kong airport already uses it to track lugages…)
