RFID technology provides a method to transmit Healthcare providers (i.e., hospitals) traditionally and receive data from a patient to health serviceuse a paper-based ‘flow chart’ to capture patient provider/medical professionals without humaninformation during registration time, which is updatedby the on duty nurse and handed over to the incomingstaff at the end of each shift. Although, the nursesspent large amount of time on updating the paperworkat the bedside of the patient, it is not always accurate,because this is handwritten.

ASDM recommends activities that are often context dependant and a variety of practices for User Interface Layer constant feedback on customer requirements, and technical decisions [11]. The HPMS uses the unique ID transmitted by RFID tags as a key to information stored in the HPITS back- end databases. For example, an RFID tag attached to a patient wristband only contains an RFID tag ID, which an application can use to retrieve patient record stored in the hospital databases. When a RFID reader reads multiple patient wristbands that have embedded RFID tags, the application lists and displays all ID’s in patient info area. Click on a particular ID will display the information for that patient.
