What is RFID? A Quick Overview
An RFID system typically includes:
- RFID Tags – Tiny transponders that store data (e.g., a unique ID).
- RFID Scanners – Handheld or fixed readers that emit radio waves to detect and read tags.
- RFID Software – Processes and interprets the tag data.
- Optional Accessories – Antennas, buzzers, stack lights, etc., for alerts and automation.
Unlike barcodes, RFID doesn’t require line of sight to read tags, and it can scan multiple tags at once from a distance. This makes RFID in asset tracking particularly powerful for large-scale or automated environments.
Advantages of RFID
Below are the top advantages of RFID and how they can help your organization:
1. No Line of Sight Required
Traditional barcodes need a direct scan, but RFID tags can be read even if they’re not visible. For instance, items piled in a box or linens in a laundry cart can be scanned all at once without unpacking them. This benefit is huge for industries like apparel, hospitality, and healthcare where quick inventory checks are essential.
2. Scan Multiple Tags Simultaneously
With RFID, you can wave the reader across a shelf and pick up dozens of tags in seconds. This can cut inventory time by 90% or more compared to scanning barcodes one by one. Data centers, for example, can quickly track hundreds of servers and components.
3. Long-Range Reads for Automation
RFID’s ability to read from a distance enables real-time monitoring of items moving through doorways, dock doors, or gates. This is a game-changer for supply chain management, as it updates inventory counts automatically when items leave or enter a building—no manual intervention required.
4. Rugged and Versatile
RFID tags come in rugged designs to withstand extreme temperatures, moisture, and grime. Some tags are built to handle autoclaving in medical labs, while others survive on outdoor equipment covered in mud or algae. This durability makes RFID more practical than barcodes in harsh conditions.
5. Less Dependence on Human Behavior
Barcodes often require a person to scan each code. In contrast, fixed RFID readers at doorways or production lines can capture data automatically. That means your employees don’t have to remember to scan an item each time it moves, reducing human error and saving time.
6. Locate Specific Assets Quickly
Because RFID can scan many tags without line of sight, you can find a single item in a crowded area. For instance, you can walk around with a handheld reader, listening for a beep as you get closer to the tag you’re searching for. This is invaluable for locating specific vehicles in a lot, particular books in a library, or one piece of equipment in a busy lab.
7. Faster Inventory and Audits
Faster scanning and simultaneous reads translate into streamlined inventory checks and asset audits. Organizations can perform audits more frequently, ensuring up-to-date records and reducing shrinkage or loss.

Disadvantages of RFID
While the benefits of RFID are significant, there are a few drawbacks you should be aware of:
1. Initial Cost
RFID tags are more expensive than barcodes—often anywhere from $0.15 to $2.00 or more, depending on durability. RFID readers, antennas, and setup also cost more. However, many businesses see rapid payback thanks to the labor savings and accuracy improvements.
2. Complex Hardware Setup
Unlike a simple barcode scanner, fixed RFID readers can be more involved. You may need multiple antennas, cables, and precise configurations to ensure good read rates—especially near metal or liquids, which can interfere with radio waves. However, this complexity does not exist if only handheld readers are used.
3. Potential Interference
RFID performance can be affected by metal surfaces, liquids, or electromagnetic noise. Proper planning and testing are crucial to overcome these challenges. Working with an experienced RFID solutions provider can help minimize interference issues.
RFID vs. Barcode: Which Should You Choose?
- Barcode Pros: Inexpensive, widely used, easy to set up.
- Barcode Cons: Needs line of sight, scans one item at a time, can be damaged easily.
- RFID Pros: No line of sight, scans multiple items, more rugged, automated tracking.
- RFID Cons: Higher upfront cost, more complex installation.
If you have a high volume of items or need to automate tracking across multiple points, RFID typically offers greater long-term value.

Key Takeaways
- RFID’s Main Advantages:
- Scan multiple tags at once, no line of sight needed, long-range reads, rugged tags, and reduced manual intervention.
- Biggest Disadvantages:
- Higher initial cost and more complex hardware setup, plus the potential for signal interference.
- Best for:
- Organizations that want faster inventory checks, automated real-time tracking, or to locate items quickly in large areas.
When you weigh the advantages of RFID against its disadvantages, you’ll find that the technology can vastly improve asset tracking across industries like manufacturing, healthcare, laboratories, and IT. Though it comes with a higher price tag and some setup complexity, the ability to read multiple tags simultaneously and track items in real time can quickly offset those costs.

FAQs on Benefits of RFID
1. Which industries see the greatest ROI from RFID?
Sectors handling large inventories or complex logistics—like manufacturing, retail, healthcare, and IT—often gain the most. They use RFID to automate tracking, cut down on errors, and speed up processes, resulting in quick payback.
2. Does RFID significantly reduce labor costs?
Yes. By scanning multiple assets at once, RFID reduces the time spent on manual checks. Employees can increase productivity by focusing on higher-value tasks.
3. Is RFID too expensive for smaller businesses?
RFID system cost has dropped in recent years, and many small companies find the savings on labor and errors justify the initial outlay. A well-planned deployment can lead to a fast return on investment.
4. How does RFID help with regulatory compliance?
RFID provides accurate, real-time data on asset locations and statuses. This visibility helps companies meet audit requirements, track sensitive items, and maintain up-to-date records for inspections.
5. Can RFID work with my existing software?
Many modern ERP and warehouse management systems support RFID or integrate through APIs. This ensures that data flows smoothly without needing a complete system overhaul.
6. Do I need special training to use RFID readers?
RFID readers are generally user-friendly. Most staff pick up the basics quickly—especially if they’re familiar with scanning devices like barcode scanners.
7. Is RFID useful only for high-value assets?
Not necessarily. RFID also benefits everyday inventory, especially in situations where assets need regular checks or frequent movement tracking. To know how RFID asset tracking can help improve your business, Schedule a Free Consultation with our Solution Expert
