Deeply Dug: RFID for Tracking

It is hard to believe that RFID tags, a technology once used to track cattle herd, are now used to track almost anything. So, what is the RFID tracking system? How is RFID used for tracking? Where can we use it? What are the types of RFID tracking tags? Today, let us deeply learn about RFID tracking through this article.

What is RFID Tracking system?

RFID tags can be read from a few feet away without being in the line of sight of the reader, making it ideal for tracking something. When you build an RFID system for tracking something, an RFID tracking system is born. The RFID tracking system is a non-contact automatic identification and tracking system consisted of RFID tags, RFID readers, and computer systems. RFID tracking systems vary according to specific applications, but all base on basic RFID systems.

How is RFID Used for Tracking?

RFID technology can identify high-speed moving objects and multiple tags at the same time, fast and convenient. RFID tags have the advantages of non-contact, globally unique ID, high precision, anti-interference, high speed, and a strong ability to adapt to the environment. RFID tags with back glue (RFID stickers) can be attached to objects easily. And the RFID reader can automatically identify and track them and transmit data back to the system, to achieve location tracking and other functions.

Top 10 Applications of RFID Tracking

1、RFID for Asset Tracking

With the development of RFID technology, there comes up with various RFID tags suited for different assets, making RFID asset tracking easier to implement. RFID anti-metal stickers can work well on objects with metals surface, which solves the problem that RFID tags are prone to metal interference.

Equipped with an appropriate RFID tag for each mobile asset, we can monitor and track enterprise resources by the RFID asset system, enabling it to grasp the use and flow of resources at any time to achieve asset information management, improve management efficiency, and ensure the safety of assets.

2、RFID for Tracking Inventory

RFID technology has become a powerful tool for intelligent warehouse management, which can easily realize the automation of inventory tracking and reporting. Attach an RFID tag to any individual inventory item, which contains coded digital data about the item in stock, such as model number, batch number, etc.

After the tag is scanned by an RFID reader, the data will be automatically recorded in a big database. Automated asset tracking and reporting saves 18 hours of work per month and reduces the possibility of human error.

3、RFID for Vehicle Tracking

RFID technology can identify and track high-speed moving objects in a harsh environment, especially suitable for vehicle tracking. It has been widely used in intelligent buses, logistics vehicle tracking, vehicle rental, parking, car tracking and sales, and other fields to achieve vehicle monitoring and tracking, improve the efficiency of vehicle management, enhance the user experience, promote car sales, and so on.

RFID tags used in vehicle tracking are generally UHF tags, but it should be selected according to the specific application. Each label has different characteristics. For example, 2.4G active tag identification distance is relatively long; windshield tags can be directly affixed to the car windshield, more convenient; ordinary high-frequency or UHF tags are relatively cheap.

4、RFID for Tool Tracking

How to manage tools in an orderly and efficient manner, such as finding them accurately, preventing theft and damage, is a challenge for business managers, but RFID technology changes this status.

By attaching RFID tags to each appliance, hundreds or thousands of tools can be maintained and managed with minimal loss and replacement. Building an RFID tool tracking system, the user can see the inventory room, the toolbar, and even the mobile toolbox. RFID tool tracking brings greater benefits for construction, medical, manufacturing, or any industry or company with thousands of tools.

5、RFID for Tracking Medication

As the best automatic identification and tracking technology at present, as well as its anti-counterfeiting ability, RFID technology, is of great revolutionary significance in the information management of the pharmaceutical industry.

Attaching RFID tags on the package of medicine, on the one hand, it can prevent counterfeit traceability and track the original information of medicine, on the other hand, it also plays a great role in hospital medicine inventory tracking, making it convenient for managers to quickly grasp the inventory situation, replenish drugs in time, and ensure the safety of drug inventory.

6、RFID for Baggage Tracking

RFID baggage tracking can improve operational efficiency and security and provide a better experience for passengers. RFID tags, with the features of easy to install, low cost, and wear-resistant, are considered to be the most reliable and unique identifiers for single baggage transportation. And the successful reading rate of RFID baggage tags is close to 99%, far higher than the traditional barcode tags around 80%.

In 2008, HKIA became the first international airport in the world to incorporate RFID technology into its baggage handling system, as well as the first airport to incorporate RFID readers into its automated baggage handling system.

7、RFID for Human Tracking

RFID personnel positioning system automatically tracks the location of personnel through long-distance, non-contact collection of electronic tag information, very suitable for tracking special groups, such as people with intellectual disabilities, Alzheimer’s disease patients, and people in prison, detention, or drug rehabilitation. If someone exceeds the set range, the system can automatically alarm to prevent the person from getting lost or running away.

Personnel positioning and tracking system commonly uses 2.4G active tags. However, 13.56MHz wristband tags or RFID cards are often used in nursing homes, campuses, or prisons.

8、RFID for Package Tracking

RFID for package tracking has a great benefit confirmed by many express or logistics companies. Express companies can track all products and packages through a network of RFID tags from various classification stations, improving the efficiency of express delivery, and enhancing the user experience.

Attaching an RFID tag to each package, with important information such as tracking code, sender, recipient, destination, bar code, or product information, can reduce the processing time of parcels, achieve automatically tracking of each link, and avoid the loss of items in the process of circulation.

9、RFID for Animal Tracking

RFID animal tracking management system has become a development trend. More than 20 countries and regions around the world have used RFID technology to track and trace the production process of animal food and achieved good results.

The animal tracking management system can record and monitor the whole feeding process of animals from birth to entering the slaughterhouse, including feeding management, veterinary prevention, disease treatment, feed use. Moreover, after animal products enter the supermarket, consumers can query the whole process of animal products through the unique identification number of each animal.

10、RFID for Laundry Tracking

It is a great challenge to track and manage the washing process, washing times, inventory status, and effective classification of each piece of linen. RFID technology solves this problem, making laundry management more transparent and efficient.

Sewing an RFID PPS laundry label or RFID textile laundry tag on each piece of linen, can make them tracked automatically. RFID laundry tags are durable that they can be reused after the linen is scrapped. The RFID system can track the number of washing times to predict the service life of the current linen for the user and provide forecast data for the procurement plan.
