ABSTRACT The present invention discusses efficient time management in various applications, through a queue management system. The system presented here uses GSM technology, a thermal printer for printing token number and a microcontroller, making it embedded in nature. The entire system is controlled by a master controller through embedded program, and the access to the GSM is achieved through standard RS232 protocol (Serial Communication). Though designed for clinical application i.e. doctor patient interaction, the system can be suitably modified and extended further to serve many such applications. The design depends extensively on the perfect synchronization between the three major elements of the system GSM and microcontroller. The system has been evaluated successfully and the results obtained are promising. Following invention is described in detail with the help of Figure 1 of sheet 1 showing the block diagram of the present invention.
