As it happens, businesses are bullish on deploying technological solutions to solve the challenges posed by lack of data and inaccuracy in data capture methods, affecting business operations, access control, inventory control, asset verifications and audits, asset visibility, etc. Technologies, such as the Internet of Things (IoT), Radio Frequency Identification (RFID), Barcode, BLE, LoRa, LTE-m, etc. are proven to be successful in such business settings.
RFID technology, in particular, has been beneficial in designing a low-cost asset and inventory tracking system that is simplifying a number of distinct operations in businesses such as retail, healthcare, education institutions, government, banking, hospitality, and logistics. RFID uses RAIN RFID labels and readers, along with asset tracking software, to accurately identify and track assets.
However, how do we build an RFID asset tracking system? What are some benefits of this system in various businesses?
Let’s understand the particulars of an RFID tracking system and how to design one such solution in detail.
RFID Asset Tracking System
RFID Asset tracking systems have transformed asset tracking across various retail, healthcare, hospitality, travel, IT, restaurant, etc. An RFID asset tracking system involves the use of radio frequency-based signals to identify and track tags attached to objects.
Components of an RFID Asset Tracking System
To develop an effective RFID asset tracking system, several key components are required:
1. RFID Readers
RFID readers are needed to retrieve the information from RFID-tagged assets. RFID Readers emit radio waves to detect RFID tags within range. They can be handheld readers like the Zebra RFD40 SLED or fixed RFID readers, say the Zebra FX9600 reader.
The reader captures the information stored in the tag and sends it to a central system for processing.
2. RFID Tags or Labels
RFID tags, hard tags, or labels, are small devices that contain a microchip and an antenna. The RFID chip is also known as IC. The RFID microchip stores information about the asset, say asset name, serial no., brand, expiry, etc. while the antenna transmits data to the reader. The tag antenna extends its range, the better the tag design, the better the read accuracy of the tag.
3. Database
A database is required to store asset information. The tag and asset information are mapped and saved in the database. It also contains information processed by an asset tracking software including asset locations, movements, and statuses.
4. Software System
To process the data collected from RFID readers and antennas, we would also need middleware software. The software is the bridge between the RFID hardware and the business applications. It can filter, aggregate, and analyze data, providing actionable insights.
For example, in a laundry management system, the software can help users track the laundry coming in for a wash, already washed and folded and stored, delivered to customers, etc.
5. User Interface
A user-friendly interface is also necessary for the asset tracking system. The UI allows users to interact with the solution easily, retrieving asset information and generating reports. It makes everything as simple as clicking a button.
Steps to Build an RFID Asset Tracking System
To design an asset tracking system, whether it is for retail, healthcare, laundry, manufacturing, IT, or hospitality, we need to finalize a few things beforehand.
a. Define Requirements
The first step is to assess the specific needs of the business regarding asset tracking, such as the types of assets to track, no. of total assets in the inventory, required accuracy, tracking area, and the budget.
b. Select RFID Tags and Readers
Choose the appropriate types of RFID tags and readers based on the environment, range, and asset characteristics. For metal assets in IT, say laptops, use RFID Anti-metal tags for laptop tracking. For harsh conditions, durable hard tags are necessary. For assets exposed to harsh conditions, say manufacturing and other industrial setting with high temperature, durable RFID hard tags are necessary.
c. Develop Middleware
The next step is, based on asset type and the business operations, to create or implement middleware that can handle data processing and integration with other business systems, such as inventory management or ERP software.
d. Set Up a Database
Also, design a database structure that can efficiently store and manage the asset data collected from the RFID system. It must also store the list of all the assets with the premises, how they are used, etc.
e. Implement User Interfaces
Now create an intuitive user interface for staff to monitor and manage assets effectively. Mobile applications and software interfaces allow users to view reports and insights easily.
f. Pilot Testing
Before implementing the solution at the business premises, conduct pilot tests to identify any issues in the system and make necessary adjustments before full deployment. Check for information getting captured at the various entry and exit points.
g. Full Deployment and Training
Roll out the system across the organization and provide staff training to ensure they can effectively use the system.
Benefits of RFID Asset Tracking Systems
An RFID asset tracking system offers numerous advantages across various business sectors. Be it laundry asset tracking, linen management, laptop tracking, retail asset tracking, inventory management, or tool tracking, the asset tracking system offers numerous benefits as follows:
1. Improved Inventory Management
Businesses such as IT, legal, retail, etc. can achieve real-time visibility of inventory levels, reducing frequent stockouts and overstock situations. The solution improves inventory control, replenishment, etc. It also leads to better resource allocation and cost savings.
2. Enhanced Operational Efficiency
RFID technology automates tracking processes, reducing manual labor and human errors. The RFID-based asset tracking solution also enhances the overall efficiency and allows staff members to focus on higher-value tasks, resulting in higher productivity.
3. Increased Asset Security
RFID systems can provide alerts for unauthorized access or movement of assets, enhancing security and reducing losses.
4. Better Data Accuracy
RFID systems minimize the risk of data entry errors associated with manual tracking methods, leading to more reliable information for decision-making.
5. Streamlined Supply Chain Management
By providing instant access to asset information, RFID enhances collaboration among supply chain partners, improving transparency and responsiveness.
6. Cost Savings
Although the initial investment in RFID technology can be significant, the long-term savings from improved efficiency, reduced labor costs, and decreased losses often outweigh these costs. The cost of RFID tags, readers, and antennas is also coming down with wider adoption and global production of RFID tags.
To summarize, building an RFID asset tracking system involves careful planning and the integration of various components, from tags, antennas, and readers to software and databases. The benefits of such systems are vast, including improved inventory management, enhanced operational efficiency, and increased asset security, making RFID a valuable solution for businesses in IT, retail, healthcare, and manufacturing, looking to optimize their asset-tracking processes.
