Korea’s Kangnam Hospital has deployed an intelligent queue management system based on radio frequency identification (RFID) at its outpatient center. Every patient who registers at the center is issued an integrated active-passive RFID tag, which identifies the patient and provides the patient’s location. The patient is also assigned a locker, which can be locked or unlocked with the tag. On the basis of the patient’s location and through information provided on display panels installed at strategic locations in the center, the system guides the patient as he or she journeys through the center in such a way as to shorten the patient’s waiting time. This system was developed jointly by Korea’s information technology leader Choongwae IT and Singapore’s healthcare technology company Cadi Scientific.
