RFID in Japan

Chiyoda Maintenance developed a system to easily check "if everyone is here" using RFID. Imagine an excursion with your colleagues. "Alright, it's free time. Go play enjoy whatever you want. Just come back in 30 minutes, okay?" 30 minutes later, "is everyone here?" but what if you've got 400 colleagues travelling with you?

As you might have already guessed, the system uses RFID tags carried by people and a handheld device that reads the tags and shows a list of people who are missing. The read range is about 7-10 meters and takes about 5 sec to check 20 people but the system somehow supports as many as 400 people.

The company, Chiyoda Mainteneace -- their main business is actually to provide services for nuclear facilities.
