RFID for Asset Management: What? Why? Where? How?

RFID has revolutionized many industries, including asset management. As we all know, asset management is both important and complex. It has the characteristics of large quantities, many kinds, high value, long use cycle that make it more difficult to manage. But the rise of RFID technology has solved this problem perfectly. So what is the RFID system? How does it work in asset management? How to choose RFID tags for asset management? This article will discuss it and share it with you.

What is RFID System?

The RFID system is a contactless automatic identification system, which automatically identifies the target object and obtains relevant data through radio frequency wireless signals.

It is composed of RFID tags, readers, and computer networks. The RFID system uses electronic tags to identify objects and exchange the data with the reader through radio waves. The reader can transmit the read and write commands of the host to the tag, and then transmit the data returned to the host. The host data exchange and management system are responsible for the storage, management, and control of the RFID tag data information.

RFID systems commonly used for asset management are RFID HF system and RFID UHF system.

1、RFID HF System

High-frequency RFID is one of the RFID technologies, and the typical operating frequency is 13.56MHz. The inductor at this frequency no longer needs to be wound by coil, and the antenna can be made by etching or printing. Sensors generally work through load modulation. The features as follows:

  • Except for metal and moisture, the wavelength of this frequency can pass through most materials
  • More choices of chip capacity, and higher security performance
  • The system construction cost is moderate
  • Low cost of electronic tags
  • Fewer data stored in the tag
  • Short reading distance ( passive, typical reading distance is 10cm)
  • RFID tags come in a variety of shapes (cards, ring, button, pen, etc.)
  • Reading antenna directivity is not strong

2、RFID UHF System

The working frequency of the UHF system is generally more than 400MHz, and the typical working frequency is 860~960MHz. UHF systems are also supported by many international standards in these frequency bands. The core technologies of UHF RFID mainly include anti-collision algorithms, low-power chip design, UHF tag antenna design, test authentication, etc. The features as follows:

  • Large data storage capacity
  • Fast reading speed and Read multiple tags simultaneously
  • Anti-conflict & Strong penetration
  • Long reading distance (up to a few meters to more than ten meters)
  • Good performance to adapt to the high-speed movement of objects
  • The high cost of RFID tags and readers

Why choose the RFID system for asset management?

RFID assets management system is an asset information management system designed by using RFID technology, which can achieve long-distance, fast, batch identification with anti-pollution ability. The system carries on the scientific management around the “in, out, use” links of assets, completes the daily business management of assets, such as procurement, registration, allocation, maintenance, scrapping, and provides the whole life cycle tracking management of equipment. Why does more and more enterprise asset management choose the RFID system? Here are some reasons.

  • Long-distance rapid identification, high reliability, high confidentiality, easy to operate, and expand.
  • The asset statement is clear at a glance, making it easy to query at any time.
  • Effectively and accurately identify, collect, record, and track the data and information of the enterprise’s fixed assets to ensure the rational use of the assets.
  • Solve the problems of disorder and poor real-time performance in enterprise asset management.
  • The whole life cycle management of assets is realized, and the system can update the dynamics of assets in real-time.
  • Users count and query the asset data through the visual system operation interface.
  • Each fixed asset has its own unique identification, which is convenient to grade and find.
  • Multiple asset inventory methods, including online, offline, single person, collaborative, etc.
  • Event Reminder: It can remind the things that need to be dealt with, support SMS notification.

What can the RFID system achieve in asset management?

RFID asset management system is not static. According to different application environments, the design of the system is also very different. The realization of the function is also closely related to the specific requirements of the application. What is the role of RFID systems in asset management? What can be achieved? Well, here are some common examples.

1、One-stop Management

It mainly includes the daily work of adding, modifying, withdrawing, transferring, deleting, borrowing, returning, maintaining, calculating depreciation rate, and salvage rate of fixed assets.

2、Asset Inventory

Through the real-time data collection of RFID, the rapid registration and real-time update of asset information can be realized, including delivery, warehousing, transfer, and inventory. At the same time, inventory history can be automatically saved and can be queried at any time.

3、Batch Storage

Batch input of assets can be realized. The storage information of assets can be synchronously updated to the background by automatic scanning and storage of RFID equipment, to improve the storage efficiency.

4、Automatic Alarm

For asset loss, illegal label disassembly, unauthorized movement, and other conditions, the system can view and deal with alarm information in real-time in the management interface.

5、Report Analysis

The RFID system can realize the query and management of asset-related management information, personnel & department information, running status, data reports, etc. Then it is capable of making a data report according to the management requirements.

Where can you use it? (Applications)

RFID asset management system can be applied to all walks of life, making asset management automatic and intelligent and realizing asset information management.

  • Factory equipment fixed assets
  • Office supplies asset management
  • Instrumental asset management
  • Firearm management
  • Hospital and Aged Care asset management
  • Mobile maintenance management
  • School and educational assets
  • IT asset tracking
  • Trees management
  • Authenticate goods and materials management
  • AV (Audio-Visual) production equipment management

How to Choose the Asset Management Tag?

In fixed assets management, there are two kinds of RFID tags: Common RFID tags and Anti-metal tags. Ordinary labels do not work on metal surfaces, but the anti-metal tags can. Among them, anti-metal tags include a variety of forms, such as flexible anti-metal tags, ABS hard tags, PCB tags, ceramic tags, etc.  Ordinary RFID tags are suitable for wood, plastic, paper, and other assets, while anti-metal labels are fit for assets that made of metal materials.
