Radio frequency identification tags are computer chips linked to a tiny antenna that is used to convey information electronically through a close RFID reader.The use of RFIDs in health care is a promising progress in IT,but also raises vital legal and social issues.


They particularly improve patient safety, but also pose some physical risks, deter patient privacy and present other common hazards. RFIDs use wireless technology to converse data through signals over radio frequency range of the electromagnetic spectrum. The microchip stores the data which is then packaged so that they can be attached to human body (Daniel, Albert and Mike 2007). There are two main types of RFID tags, active and passive. The passive tags have no internal power supply. Their operation is by converting the radio frequency energy from a reader device to signals that convey stored data for a short distance. They currently have limited amounts of data storage hence a limited functionality. This is because the information they have cannot be altered (Debora, Vergil and Slee 2008). This is opposed to the active RFID tags which contain an internal battery. This provides better reliability, on-tag data processing, longer transmission ranges, and greater data storage. Their capacity to process data internally permits expanded capabilities in the future. On the other hand, their superior transmission range presents an extra substantial risk to patients’ privacy and data confidentiality (Jerry, 2007). RFID technology has several advantages. First, it is deployed in monitoring patient wait times in real time. Reusable active technology allows an ER see precisely the number of people in the queue and the patient’s length of wait time. ...
