RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.
In October 2004, the FDA approved the USA's first RFID chips that can be implanted in humans. The 134 kHz RFID chips, from VeriChip Corp. can incorporate personal medical information and could save lives and limit injuries from errors in medical treatments, according to the company.
An RFID (Radio Frequency Identification) chip is a small device that uses radio waves to transmit data wirelessly. It consists of a microchip and an antenna, encapsulated in a tiny package. These chips are often embedded in various items, such as cards, tags, labels, or even implanted in living beings.
A small chip -- known as an RFID tag -- is attached to or implanted in an object. The tags contain information that can be read at short range via radio waves. The chip and reader don't have to touch. Some RFID tags can be powered by a battery, but many RFID tags aren't self-powered.
Rather than waiting to pay a toll at a tollbooth or shelling out coins at a token counter, passengers use RFID chip-embedded passes like debit cards. But would you entrust your medical history to an RFID tag?
RFID chips use radio signals to transmit data over short distances. They are used typically for security, tracking, and identification purposes. RFID chips can be paired with other circuitry to create tags or readers that also use radio frequency identification (RFID) technology.
RFID is an acronym for Radio Frequency Identification which means RFID is the wireless, non-contact use of radio frequency waves to transfer data and identify objects, animals, or humans. RFID systems are usually comprised of an RFID reader, RFID tags, and antennas.
Radio Frequency Identification (RFID) is a technology that uses radio waves to passively identify a tagged object. It is used in several commercial and industrial applications, from tracking...
RFID or radio frequency identification is a technology that facilitates the wireless discovery and tracking of any object using high-frequency radio waves. At a very basic level, RFID consists of two things: a tag and a receiver. A tag is attached to the object that needs to be identified/tracked.
RFID technology uses small chips to store and transmit information wirelessly for tracking and identification purposes. Learn all about RFID.
