The inconvenience encountered in many public dealing places like restaurants, banks, canteens etc. where people normally follow queue system has called for many solutions to speed up and ease the dealings. In this paper we show a low power microcontroller based smart token number display system to overcome the inconvenience mentioned above. Bank token number display project is built using Atmega328 Microcontroller and seven segment display capable to display four digits using transistor drivers. The token number is entered through terminal software from PC which then sends same data to microcontroller using zigbee module. We are here using large size 4 digit seven segment display board. We are using android app for voice announcement. The data is sent to android phone using bluetooth module HC-05.
Token issue systems are ideal for banks, airports, public dealing offices, hospitals,doctor’s clinics, restaurants and other such places where people have to wait in line for their turn. These systems allow customers to wait without having to stand in queue. Their number is displayed on seven segment. In this way the device serves the purpose of improving the performance of the banking system, E-Seva centres for bill payments. This makes comfortable services to it’s customers.
