Radio Frequency Identification - RFID
Radio Frequency Identification (RFID) is a process of transmitting data to a wireless receiver with radio waves. A RFID chip consists of a small microchip, and an antenna. There are three different types of RFID tags, passive, active, and semi-active. Active and semi-active RFID tags use a battery to power their internal circuits, which enables it to broadcast a signal to the reader. Passive RFIDs have no internal power supply, an incoming radio frequency is picked up by the antenna and that frequency powers the tag and enables it to transmit a response to the reader. Active tags are known to be more reliable and faster than Passive tags.
Health IT - RFID tags can be attached to medical ID bracelets, or inserted under the skin with a non-invasive surgical procedure. The tags can store information like a patients allergies, current medications, and past hospital visits. These tags can also monitor the patients whereabouts in a hospital. It can also be used to track down doctors in case of an emergency.
Asset Management - Being able to locate a mobile item such as a life support machine will help utilize the amount of time needed to find a machine for the staff. Hospitals and doctors will be able to identify what machines they lack or need.
Patient Care - Being able to correctly identify a patient and know where that patient or doctor is at all times, results in improved safety and bed placement.
Inventory Management - Being able to identify what you actually have in your current inventory and where that inventory is being consumed, reduces out-of-stock situations and the amount of consumables not being billed to a patient.
