RFID vs QR Code Asset Tracking: Which is Right for You?
A comprehensive comparison of RFID and QR code tracking technologies, helping you choose the right solution for your asset management needs.
Choosing between RFID and QR code tracking is one of the most important decisions when implementing an asset management system. Both technologies have distinct advantages and limitations, and the right choice depends on your specific requirements, budget, and operational environment. This guide provides a comprehensive comparison to help you make an informed decision for your organisation.

Understanding RFID Technology
Radio Frequency Identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of tags (containing a microchip and antenna), readers, and software. When a tag passes near a reader, it transmits its unique identifier wirelessly. RFID comes in two main types: passive tags (powered by the reader's signal) and active tags (battery-powered with longer range).
- Passive RFID: No battery required, range up to 10 metres, lower cost per tag
- Active RFID: Battery-powered, range up to 100+ metres, higher cost
- No line of sight required—can read through packaging and materials
- Bulk scanning capability—read hundreds of tags per second
- More durable tags suitable for harsh environments
Understanding QR Code Technology
QR (Quick Response) codes are two-dimensional barcodes that store information in a pattern of black squares on a white background. Unlike traditional barcodes, QR codes can store significantly more data and can be scanned using any smartphone camera. QR codes are generated digitally and can be printed on various materials, making them highly versatile and cost-effective.
- Scannable with any smartphone—no special hardware required
- Extremely low cost—can be printed on standard labels
- Can store URLs, text, and other data types
- Easy to generate and replace if damaged
- Visual verification possible—users can see what they're scanning
Cost Comparison: RFID vs QR Codes
Cost is often the deciding factor between RFID and QR codes. QR codes can be printed for pennies, while RFID tags range from £0.10 for basic passive tags to £20+ for rugged active tags. However, the total cost of ownership includes readers, software, and ongoing maintenance. QR codes require only smartphones (which staff likely already have), while RFID requires dedicated readers costing £500-£5,000+.
- QR code labels: £0.01-£0.05 per label
- Passive RFID tags: £0.10-£2.00 per tag
- Active RFID tags: £10-£50+ per tag
- RFID readers: £500-£5,000+ per unit
- QR scanning: Free with existing smartphones
- Consider total cost of ownership, not just tag costs
When to Choose RFID
RFID excels in environments requiring speed, automation, and hands-free operation. Choose RFID when you need to track items moving through checkpoints automatically, scan large volumes quickly, track items in challenging environments (wet, dirty, or where labels might be obscured), or when line-of-sight scanning isn't practical.
- High-volume environments: Warehouses, distribution centres
- Automated tracking: Items passing through portals or checkpoints
- Challenging conditions: Wet, dirty, or obscured assets
- Time-critical operations: When manual scanning is too slow
- Tracking without human intervention required
- Items frequently moving between locations
When to Choose QR Codes
QR codes are ideal for organisations prioritising simplicity, cost-effectiveness, and flexibility. Choose QR codes when you have a moderate number of assets, budget constraints, staff already carrying smartphones, or when you need quick deployment without significant infrastructure investment. QR codes also work well when you want users to access detailed information by scanning.
- Budget-conscious deployments: Minimal upfront investment
- Office environments: Furniture, equipment, IT assets
- User-driven tracking: Staff check-in/check-out items
- Information access: Scanning links to detailed asset records
- Quick deployment: No special hardware to procure and install
- Multi-site organisations: Easy to roll out without infrastructure
Hybrid Approaches: Best of Both Worlds
Many organisations find that a hybrid approach works best—using RFID for high-value or high-movement items and QR codes for general asset tracking. For example, you might use RFID to track IT equipment through a returns desk while using QR codes for furniture and fixtures. Modern asset management platforms like Camio support both technologies, allowing you to choose the right method for each use case.
- Use RFID for high-value, frequently moving items
- Use QR codes for stationary assets and general inventory
- Modern platforms support both technologies simultaneously
- Start with QR codes, add RFID for specific use cases
- Consider future needs when selecting your platform
How Camio Supports Both Technologies
Camio provides flexible asset tracking supporting both QR codes and RFID. Generate QR code labels instantly for any asset and scan them using our mobile app or any smartphone camera. For RFID requirements, Camio integrates with leading RFID readers and supports bulk scanning workflows. This flexibility means you can start with QR codes and add RFID capabilities as your needs evolve, without changing platforms.
Frequently Asked Questions
Common questions about rfid tracking
Is RFID better than QR codes for asset tracking?
Neither is universally better—it depends on your needs. RFID offers faster bulk scanning and doesn't require line of sight, making it ideal for warehouses and high-volume environments. QR codes are more cost-effective, require no special hardware, and work well for office environments and user-driven tracking. Many organisations use both.
How much do RFID tags cost compared to QR codes?
QR code labels cost £0.01-£0.05 each and can be printed on any label printer. Passive RFID tags cost £0.10-£2.00 each, while active tags with batteries cost £10-£50+. However, RFID also requires readers (£500-£5,000+), while QR codes can be scanned with existing smartphones at no additional cost.
Can I use both RFID and QR codes in the same system?
Yes, modern asset management platforms like Camio support both technologies. This hybrid approach lets you use RFID for high-value or high-movement items while using cost-effective QR codes for general assets. You get the benefits of both without being locked into one technology.
What range do RFID and QR codes have?
QR codes require line of sight and typically work within 30-50cm on smartphones. Passive RFID can be read from up to 10 metres away without line of sight. Active RFID tags with batteries can be read from 100+ metres. The right choice depends on whether you need automated or manual scanning.
Which is more secure—RFID or QR codes?
Both can be secure when implemented properly. QR codes link to your secure platform where access controls apply. RFID tags can be encrypted and password-protected. The key security considerations are your platform's access controls rather than the tracking technology itself.
