Which uses electromagnetic fields to automatically identify and track tags attached to objects?

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. RFID can be used for remote monitoring of product flow in the factories and warehouses. RFID can also be used in tracing personnel. The possibilities are limited only by imagination

Description of the tool

Methodology

The technology enables the reading of tags from a distance and replaces the previously used barcode-tags, which tend to get lost or torn into pieces. Comparing with barcode tracking, RFID enables longer ranges between the product and reader. The tag has not to be line of sight and it can even be placed inside the packaging material.

Case Study

Using RFID on tracking the soft drink pallets on drinks factory. It was proven to be feasible for maintaining up-to-date storage inventory.

Objective of the tool

Outcomes Expected

More efficient tracking of the product flow inside the factory. More up to date warehouse registry.

Why Used

Using RFID tags of product tracking helps the manufacturer in recognizing the status quo in the company. Real-time tracking of the warehouse helps in production planning as the storage room can be optimized.

Scope of the tool

Where Used

In production lines and warehouses. Even in transportation and sales premises. All kinds of products. Can be joined with a barcode.

How Used

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. There are several types of RFID-tags and readers.

Low frequency tags can be used for example in tracking animals and on access controls. High frequency tags are suitable for libraries, ID-cards etc. Ultra-high frequency is used in supply chains and manufacturing, electronic tolls, tracking and timing: they can be divided in passive and active devices. The employment of the RFID depends on the type. Passive RFID range can be up to 10 meters whereas active RFID can reach 100 meters.

Which uses electromagnetic fields to automatically identify and track tags attached to objects?

RFID is a way of tracking assets, using electromagnetic fields to automatically identify and track tags attached to objects. A scalable and cost-effective solution to tracking needs.

There are two forms of RFID: passive and active.

Active Rfid systems use battery-powered Rfid tags that broadcast a signal. Active RFID systems are used as a Real-time location system (RTLS). There are two forms of Active RFID. The first being RFID ‘transponders’ they only respond when they are asked where they are this is the best form for tracking that does not require the frequent updates of the position. Typical cost is approx $20 per tag.

Smart Beacons

The best tracking for a system that requires frequent update is RFID ‘beacons’. These beacons send our their information every 3-5 seconds. Because of their frequent information output, battery life is reduced and beacons, therefore, have a higher total cost of ownership.

RFID technology

Passive RFID tags have no internal power source, and hence have a short range and can only carry a small amount of data. A passive RFID system employs an RFID reader to send a signal to the antenna on the RFID tag which forces the tag to send its information back to the reader. The pro’s of Passive RFID is that it has a much cheaper cost than active (approx. $0.05) as it has no battery and is much smaller in size and tags have a longer lifetime. However, because they have no battery they have limited range and storage.

RFID radio frequency identification

Each form of RFID has its niche market – passive RFID fits more towards tagging products and equipment for auditing purposes and anti-theft, whereas active ‘transponders’ are best suited for situations such as tolling. RFID ‘beacons’ are best suited for situations such as tracking assets which move frequently and require constant visibility.

Which uses electromagnetic fields to automatically identify and track tags attached to objects?

After completing extensive studies in low power wide area networking Andrew found himself as interested in the literature as the technology itself. Andrew now writes engaging and informative content at our sunny office in Melbourne, for an international audience.

What uses electromagnetic fields to automatically identify and track of an object animal or person?

What is RFID (radio frequency identification)? 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.

Which of the following is used to identify and track tags attached to objects?

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter.

Which IOT technology uses electromagnetic fields to identify and track tags attached to items?

RFID is short for “radio frequency identification.” This technology uses electromagnetic fields to identify and track tags attached to objects automatically. The tags contain electronically stored information.

What is an RFID used for?

RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.
