###### Abstract
In 2013, a study was conducted to observe the usability and safety of different NFC operating modes. The study [1] highlighted the advantages and disadvantages of NFC concerning usability and security. It evaluated the current availability and the specific features providing security and found that NFC devices did not provide generic security protocols but retained application-specific protocols. Another study [2] proposed an automated healthcare system that consisted of NFC, sensors (heat, pressure, and ECD), a ZigBee module, and an imaging device. It focused on patient identification using an NFC card that each patient had. The measured medical records were transmitted to the imaging device using Zigbee. The goal was to shorten the waiting and check-in process at the hospital while interposing, before the patient was admitted, the added value of baseline test results using the sensors. Medical records were sent via Zigbee to the doctor, so the patient did not need to carry a vast medical communication, only an NFC card. However, over the years, technology has evolved, and we have seen a significant increase in the number of NFC cards. Considering the use of mobile devices, it is appropriate to use a mobile device with NFC-card-emulation capability to the process data and to make the hospital stay even more comfortable. In healthcare delivery, efficiency and accuracy are two essential aspects. Of course, care is also taken to secure data thoroughly and minimize errors. The NFC wireless communication, available on most phones, can be used for the unique identification of patients in the hospital. [PERSON] et al. claim that the use of NFC will reduce the number of errors in providing wrong treatment to patients in hospitals. The use of NFC may represent a big step toward the automation of healthcare [3; 4; 5]. In another study [4] a system of using NFC in a mobile device and kiosk was proposed, based on the principle of selecting a time window to make an appointment. The study was a follow-up to the study of [PERSON] et al. The kiosk considered when the card was beped. At the same time, the patient could choose the available physicians. Once all patients had been admitted, the system automatically prioritized patients based on age and patient profile but did not consider the type of disease. This system also assigned the patient to the appropriate doctors for the selected consultation time. The study took advantage of the ability to display the current ranking on an LCD monitor. The order was automatically adjusted according to the set criteria. In this case, a local database was used to which all the devices were connected. The study focused on the waiting list of patients from the kiosk data, essential patient information, appointment confirmation, and new appointments. Patients and medical staff had created names and passwords to access the data. A study by [PERSON] et al. proposed intelligent health-record management with NFC-enabled mobile device security. The proposed system provided integration and mobility across hospitals. It provided the possibility of a reliable health history with selective sharing and easy access. The study used the principle of NFC based on a case study in hospitals with a heightened number of people, suggesting an improvement in health management with high availability [5; 6; 7]. The study by [PERSON] focused on patients' interest in online doctors. It was a systematic study that compared 63 studies. The result was that telemedicine had a positive response in several parts of the world. With this fact, there is room for improvement of contemporary medicine, for example, using mobile communication devices [8; 9; 10; 11; 12; 13].
