  • The Radio Frequency Identification

    The innovation of the RFID chip or the Radio Frequency Identification has been a critical piece of technology that has been around since the 1950’s.. There are several methods of identification, but the most common is to store a serial number that identifies a person or object, and perhaps other information, on a microchip known as identity chip. A microchip implant could be used as a virtual barricade, to limit movement, and even to act as a tag for prisoners. In the realm of medicine, it could be used to save medical records for patients, records that could be pulled up anywhere in case of an emergency. It could also be used to monitor people with Alzheimer’s disease. However, as with most technology, RFID technology privacy and security…

  • Radio Frequency Identification (RFID)

    Radio Frequency Identification (RFID) Radio-Frequency Identification (RFID) is a wireless technology that uses radio waves to read and capture information stored on a tag. A RFID reader can read the tag from upto several feet away. However unlike barcode, it does not need to be within direct line-of-sight of the reader to be scanned. There are two different type of tags: one is passive tag which collects energy from a nearby RFID reader 's radio waves; and another one is active tag that has a…

  • Radio-Frequency Identification: RFID Tags

    Radio-frequency identification also known as RFID is the use of wireless technology that uses electromagnetic fields to transfer data, for the purpose of automatically identifying and tracking RFID tags that are attached to objects. The RFID tags will have information that is electronically stored. Some of the tags will be powered by an electromagnetic induction from magnetic fields that are produced near the readers. Certain RFID tags will collect energy from the reader’s radio waves and will…
