In the past years, Internet of Things (IoT) has been focused and fused with wireless sensor node such as RFID, NFC tag and small sensor nodes, especially for hospital environment with mobile device. Due to the weakness characteristics of wireless signals, unauthorized person can access easier to hospital networks in wireless part than wired network systems. This may induced in several security problems. Therefore, a lot of threats, attacks and vulnerability are occurred in wireless surroundings because of their limited resources such as small memory and low computation capability in wireless sensor network. RFID is often utilized as a prerequisite for the IoT in healthcare system. We surveyed and analyzed the technologies and characteristics of RFID and its application based on IoT.
