Patient-centeredness is becoming more and more important in the healthcare industry. The growing understanding of the patient's involvement in the planning and delivery of health care is essential to this change. The primary focus of the majority of non-urgent health care services is medical appointment scheduling, which is going through significant advancements to encourage patients' active participation. The project outlines a method for creating a online appointment booking system that gives users or patients a simple way to schedule a doctor's appointment. Patients can get appointment as soon as they enter clinic because a RFID card is registered under their name, selecting their preferred appointment times and have better access when they use the Internet as a medium. Patients just need to scan their RFID cards at certain kiosks or checkpoints upon arrival at the institution to immediately alert the system of their presence. Healthcare practices may save time and effort when scheduling and managing appointments with the help of an automated patient appointment system productivity all around. The proposed work uses NodeMCU and RFID to update the contents in real time [19].
