ABSTRACT

Patient wait times have a strong influence on patient satisfaction levels. A common scenario in front of clinics, and hospitals are people standing in long queues. These people cannot do any other activity until they are served. In order to save time when standing in long queues, it is better to issue a token to each individual and call them when required. One can be occupied otherwise until that individual‘s token no is displayed or announced. Thereby reducing patient waiting times and reducing the spread of diseases in healthcare organizations.

‘Smart Token’ is a device mainly focused on hospitals to manage patients. Here we are using Arduino Uno, LCD Display, Keypad, 7-Segment Display, Bluetooth module, and Printer. A keypad is provided for the user to select respective departments , doctors, and rooms if required without the help of a receptionist and the details are displayed on the LCD display. Bluetooth module conveys the data collected which means the count of the patients to the doctors and the token number is displayed using the seven-segment display and the token is obtained from the printer.

The project is about 70 percent complete and requires additional work.
