Chapter 20: Barcode-RFID Hybrid Systems |
Summary in Brief |
In the world of industrial identification, the choice between barcodes and Radio Frequency Identification (RFID) has often been framed as a stark either-or decision. Barcodes are cheap, simple, and universally understood, but they require line-of-sight and manual scanning. RFID offers automated, bulk reading without line-of-sight but comes at a higher cost. The reality in complex supply chains, however, is that neither technology is universally superior. Instead, the most effective solutions often combine the strengths of both, creating hybrid systems that deliver redundancy, accuracy, and operational flexibility. This chapter explores the principles and practical applications of barcode-RFID hybrid systems, examining how the two technologies complement each other. We will look at real-world examples from American and European companies like Datalogic, Zebra Technologies, and Turck Vilant, alongside Chinese innovators like Idyllic Technology and others deploying hybrid tags in agriculture and logistics. The focus is on how these dual-technology systems are solving critical challenges in returnable asset tracking, warehouse automation, and supply chain visibility. |

Introduction: Beyond the Either-Or Mentality |
For decades, the identification industry has been neatly divided. On one side, the barcode: a simple, inexpensive, and universally adopted technology that requires a direct line of sight between the scanner and the code. On the other, Radio Frequency Identification (RFID): a more advanced, costlier technology that uses radio waves to identify objects without line-of-sight, enabling automatic, bulk reading . |
Many organisations have approached the question of which to adopt as a choice between these two worlds. Barcodes are chosen for their low cost and ease of implementation, particularly when manual processes are acceptable. RFID is selected when operations demand automation, high-speed bulk reading, and the ability to read through packaging. However, this binary thinking is increasingly giving way to a more nuanced and practical approach: the hybrid system. |
A hybrid system leverages the benefits of both technologies, either by equipping items with labels that contain both a printed barcode and an RFID tag, or by deploying scanning devices capable of reading both types of data. This approach provides a crucial advantage: redundancy. If an RFID tag fails, becomes damaged, or is in an environment where radio waves are disrupted, the barcode serves as a fallback. Conversely, if a barcode is dirty or obscured, the RFID tag can still be read. This dual-layer identification dramatically reduces the risk of unreadable items and ensures continuous data capture . |
The strategy delivers significant operational benefits. It reduces implementation risk by allowing companies to phase in RFID automation without abandoning their existing barcode infrastructure . For example, external partners and suppliers may still rely on barcodes for compliance, while internal operations benefit from the speed of RFID. By adopting a hybrid approach, companies can achieve consistent reporting, unified visibility, and smooth integration with enterprise systems, creating a clear path toward automation without forcing a full system overhaul . As Lowry Solutions notes, a hybrid approach can reduce implementation risk by up to 35% . |
|
Part One: The Technology - Building a Hybrid System |
A successful hybrid identification system can be implemented in two primary ways: through dual-technology tags (the 'asset' layer) or through hybrid readers (the 'infrastructure' layer). |
Dual-Technology Tags: Fusing Barcode and RFID |
The most fundamental building block of a hybrid system is the tag itself. A dual-technology tag combines a printed barcode (1D or 2D, such as a QR code) with an embedded RFID inlay in a single physical label. This is not merely a case of putting a barcode sticker on an RFID tag; the two components are designed to coexist on the same surface. |
The Recalo case study provides a clear example. The logistics provider equipped its 90,000+ returnable transport items (RTIs) with labels that combined barcodes and UHF RFID tags to ensure universal identification regardless of the technology used at a customer's site . This 'hardware coupling' creates a unique device where the integrity of one technology is intrinsically linked to the other. |
Research has pushed this concept further. A study published in IET Microwaves, Antennas & Propagation proposed a methodology to design UHF RFID tag antennas with a barcode layout, with the challenging goal of 'fusing' both technologies in a single device . In this design, the barcode pattern itself is shaped to function as the RFID antenna. This approach offers significant security advantages, as the information stored in the RFID chip and the information in the barcode structure can be combined to generate a specific ID code to authenticate the device . This 'hardware' coupling and fusion makes the device unique, with no possibility to separate the barcode from the RFID tag without damaging the whole device, providing a robust anti-counterfeiting measure . |
Hybrid Readers: The Infrastructure Layer |
The second pillar of a hybrid system is the scanning infrastructure. Hybrid readers are devices capable of reading both barcodes and RFID tags, often in a single scan or trigger pull. This eliminates the need for workers to carry and manage multiple devices. |
Datalogic's PowerScan 9600 RFID Series is a leading example of a handheld hybrid scanner. Designed for durability in industrial environments, it combines standard 1D/2D barcode reading with UHF RFID functionality . This allows workers to capture both barcode data and RFID tags with a single trigger pull, streamlining workflows and reducing inventory cycle times . The advanced RFID reader can read tags through packaging and detect items inside sealed boxes, providing visibility that barcodes alone cannot offer . |
FEIG Electronic's HyWEAR compact takes a different approach. It is a wearable hybrid device worn on the back of the hand, freeing both hands for manual material handling in warehouses and distribution centres . This reduces processing time per unit compared with conventional scanners or handheld RFID devices and uses Bluetooth and Wi-Fi to connect directly to networks . |
HID Global's HexaPad-10 BC is another example, offering a desktop form factor that seamlessly integrates RFID with a barcode module. Powered through a USB port, it consolidates both technologies into a single device, ideal for point-of-sale (POS) applications requiring concurrent RFID and barcode functionalities . |
Zebra Technologies' DS9908 hybrid scanner represents yet another form factor. Its 'one-of-a-kind hybrid design' provides maximum flexibility, seamlessly switching between handheld and hands-free scanning of barcodes and RFID at the checkout stand . In hands-free mode, it limits the scan range to prevent unintentional scanning, while in handheld mode it extends its reach to scan items in a shopping cart . |
|
Part Two: American Companies and Hybrid Solutions |
American companies are major players in providing both the hardware and the strategic guidance for barcode-RFID hybrid systems, particularly in retail, logistics, and manufacturing. |
Zebra Technologies: The Hybrid Form Factor |
Zebra Technologies offers the DS9908, a corded hybrid scanner designed specifically for retail environments. The DS9908 combines the power of an 800 MHz microprocessor, a high-resolution megapixel sensor, and Zebra's exclusive PRZM Intelligent Imaging technology to provide instant decoding of challenging barcodes and RFID tags . Its ability to dynamically switch between handheld and hands-free scanning makes it a versatile tool for point-of-sale operations, allowing store associates to scan items in a customer's cart without needing to hand off products . |
Idyllic Technology: Pushing Barcode Limits with RF Technology |
Idyllic Technology, while headquartered in France with a strong presence in the US market, has developed an innovative 'RF Barcode' technology that blurs the line between traditional and hybrid identification. This technology uses radio frequency to enhance barcode reading, extending the functional reading distance to 65 cm (25.6 inches) while achieving a depth of field of 60 cm (23.6 inches) . This allows operators to scan items from a distance, reducing the need for ladders or forklifts in warehouse settings and improving workplace safety . The system's RF Barcode technology quadrupled the speed of previous models to 4,000 scans per second, redefining efficiency in retail and logistics . This represents a different kind of hybrid: using RF to make traditional barcode reading more powerful. |
Lowry Solutions: Hybrid Strategy Consulting |
Lowry Solutions is a systems integrator that guides businesses through the decision-making process. The company explicitly recommends hybrid strategies as the 'most recommended approach' for many operations . Their rationale is that hybrid systems combine the manual scanning of barcodes with the automated capture of RFID, reducing implementation risk and allowing companies to phase in RFID without replacing existing infrastructure . |
Lowry's approach is to design workflows where both technologies operate on a single data layer through their Sonaria platform, ensuring consistent reporting, unified visibility, and smooth integration with enterprise systems . The company conducts environmental assessments to select the right tag materials, antenna placement, and reader configuration for challenging conditions . This consultative approach, focused on identifying operational requirements and building solutions around them, represents a growing trend in the industry. |
|
Part Three: European and Chinese Companies in the Hybrid Space |
While American companies lead in certain areas, European and Chinese firms are also making significant contributions to hybrid identification solutions. |
Datalogic (European): Handheld Hybrid Scanner |
Datalogic's PowerScan 9600 RFID Series, described above, is a prime example of a handheld hybrid scanner for demanding industrial environments . The scanner's advanced RFID technology can read tags through packaging and detect items inside sealed boxes, while its durable design withstands multiple drops and dust/water ingress . |
Turck Vilant (European): Hybrid Labels for RTI Tracking |
Turck Vilant Systems developed a comprehensive hybrid RFID and barcode solution for Recalo, a European logistics provider. This involved equipping crates with labels combining both barcodes and UHF RFID tags . The system was designed for fully automatic shipping confirmation and tracking using RFID gates at loading bays, while the barcode provided a fallback for manual scanning if needed . The system provides real-time visibility into RTI location, enabling optimal stock management and proactive bottleneck alerts . |
Chinese Companies and Agricultural Applications |
A significant body of Chinese research and commercial application revolves around hybrid systems for agriculture. A system developed on an Android platform combined barcode and RFID/NFC technologies for crop trait information acquisition in breeding . The system used a type of RFID/NFC tag with a high-frequency chip and a QR code on the surface for material identification. A smartphone with NFC function and a built-in camera could read both the RFID/NFC tag and the QR code, providing a low-cost, highly efficient solution for field data collection . The system was applied in seed industries and national crop variety regional trials across China . |
|
Part Four: Key Applications - Where Hybrid Systems Excel |
The hybrid approach is not a general-purpose solution; it is particularly well-suited to specific, high-value applications where redundancy and flexibility are critical. |
Returnable Transport Item (RTI) and Asset Tracking |
This is perhaps the most compelling use case for hybrid systems. RTIs are reusable assets like pallets, totes, crates, and kegs that are shared across a supply chain. The challenge is that different partners in the chain may have different scanning capabilities. A supplier might have advanced RFID gates, while a small customer may only have a barcode scanner. |
The Recalo case study illustrates this perfectly . By placing hybrid labels on all assets, the system could be read by both RFID gates for automated tracking at Recalo's logistics hub and by handheld barcode scanners at customer sites . This ensures that assets remain visible throughout their entire lifecycle, regardless of the technology used by the end-user . Coriel Solutions, a specialist in returnable asset tracking, also emphasises the use of 'durable barcodes, QR codes, and RFID/IoT tags attached to every returnable item' to achieve live visibility of location, custody, condition, and contents . Hybrid solutions for RTIs reduce losses, increase asset turns, and simplify billing by providing a complete audit trail for per-use charging models . |
Warehouse and Logistics Automation |
In warehouse operations, hybrid systems are used to automate the receiving and shipping process. Hybrid scanners like the PowerScan 9600 allow workers to capture both barcode and RFID data in a single pass, reducing task-switching and improving efficiency . FEIG's HyWEAR compact wearable further automates this by freeing both hands for material handling while still capturing data . |
Retail and Point-of-Sale (POS) |
Zebra's DS9908 is explicitly designed for POS environments, providing a hybrid scanner that can read both barcodes and RFID tags . This supports age verification, mobile payments, and checkout scanning, offering flexibility for retailers who are gradually adopting RFID technology . HID's HexaPad-10 BC desktop reader also targets POS applications, consolidating RFID and barcode into a single USB-powered device . |
|
Part Five: Benefits and Strategic Considerations |
The primary benefits of a hybrid system can be summarised as follows: |
1. Redundancy and Failover: The most critical benefit. If one technology fails (e.g., a damaged barcode or an RFID tag deactivated by metal), the other can still be used to identify the item. |
2. Flexibility: A hybrid system works with partners and customers who may not have RFID readers. It allows phased adoption of RFID without forcing partners to upgrade their infrastructure. |
3. Operational Efficiency: Hybrid readers reduce the need for workers to carry multiple devices, streamlining workflows and reducing cycle times . |
4. Security: The 'fusion' approach, where the barcode pattern itself serves as the RFID antenna, creates a unique device that is difficult to counterfeit . |
Strategic Implementation Considerations |
When implementing a hybrid system, companies face a strategic choice between the 'label' approach and the 'fusion' approach. |
The label approach is more common and simpler to implement. It involves attaching a standard barcode label and a standard RFID inlay to the same asset. This is the solution used by Recalo and Turck Vilant . The advantage is its simplicity and the ability to use off-the-shelf components. The disadvantage is that the two technologies remain separate; a counterfeiter could potentially replace one without affecting the other. |
The fusion approach involves designing the RFID antenna itself to be shaped as a barcode . This is more complex but offers superior security. As the researchers note, this 'hardware coupling' means there is no possibility to separate the barcode from the RFID tag without damaging the whole device . If one of the two information blocks is corrupted, the authentication fails . This is a more advanced solution, potentially enabled by companies like Idyllic Technology, which are bridging the gap between RF and optical identification . |
Challenges and Considerations |
While hybrid systems offer many advantages, they also come with challenges: |
Cost: Hybrid tags are more expensive than barcodes alone, though they can be cheaper than standalone RFID tags when considering the total cost of replacement and infrastructure. |
Complexity: Managing two sets of data (barcode IDs and RFID EPCs) and ensuring they are correctly synchronised requires a robust software platform. |
Tag Design: Integrating an RFID antenna and a barcode on a single label requires careful design to ensure both technologies function correctly. |
|
Part Six: The Future - Fusing Technologies and Expanding Applications |
The future of hybrid identification is moving toward tighter integration and broader application. |
Authenticated Dual-Technology Tags |
The 'fusion' approach, as demonstrated in academic research, is likely to gain commercial traction. By designing the barcode pattern to function as the RFID antenna, the device becomes a secure, authenticated dual-technology tag . This has significant implications for anti-counterfeiting and brand protection in luxury goods, pharmaceuticals, and high-value components. |
Expanding the Definition of Hybrid |
The hybrid concept may expand beyond barcodes and RFID to include other identification technologies. The agricultural system described earlier already combines RFID/NFC and QR codes . Future systems might integrate biometrics, NFC, and other identification methods. |
Wearable Hybrid Solutions |
As seen with FEIG's HyWEAR compact, wearable hybrid devices are becoming more sophisticated. The next generation will likely feature improved ergonomics, longer battery life, and more seamless integration with augmented reality (AR) systems, providing workers with real-time data overlays as they scan items. |
|
Conclusion: A Detailed Summary |
Barcode-RFID hybrid systems represent the practical, mature application of identification technology. They combine the cost efficiency and ubiquity of barcodes with the intelligence and automation of RFID, creating redundant, flexible, and secure systems that outperform either technology alone. |
The foundation of a hybrid system can be built at the tag level (a label containing both a printed barcode and an RFID tag) or the reader level (a device capable of scanning both technologies). At the tag level, a more advanced approach fuses the two technologies by designing the RFID antenna itself in the shape of a barcode, creating a single, unbreakable device. |
American companies are at the forefront of hybrid system innovation. Zebra Technologies offers the DS9908 scanner with a unique hybrid form factor that seamlessly switches between handheld and hands-free scanning . Idyllic Technology uses radio frequency to extend the reading distance of traditional barcodes, creating an 'RF Barcode' that reads from 65 cm away . Lowry Solutions provides strategic consulting and integration services for hybrid systems, recommending this approach as the 'most recommended' for many operations . |
European and Chinese companies are also driving adoption. Datalogic's PowerScan 9600 RFID Series combines rugged durability with RFID and barcode reading in a single handheld device . Turck Vilant Systems developed a hybrid solution for Recalo's 90,000+ returnable transport items, equipping them with labels combining barcodes and UHF RFID tags for universal identification . Chinese researchers have applied hybrid barcode-RFID/NFC systems to agriculture, developing low-cost, efficient data collection systems for crop breeding and precision management . |
Hybrid systems are particularly effective for returnable asset tracking and warehouse automation, where redundancy and flexibility are critical. In RTI tracking, labels combining both technologies ensure that assets can be read by both automated RFID gates and manual barcode scanners, providing continuous visibility across a supply chain with diverse technological capabilities . |
The strategic choice between a 'label' approach (separate barcode and RFID tag) and a 'fusion' approach (barcode-shaped RFID antenna) depends on the application. The label approach is simpler and cheaper, while the fusion approach offers superior security against counterfeiting . |
|
Looking ahead, hybrid systems are evolving toward tighter integration and broader application. The fusion approach is likely to gain commercial traction for brand protection. Wearable hybrid devices are improving ergonomics and battery life. The hybrid concept may expand to include biometrics and NFC. In the end, the choice between barcode and RFID is increasingly irrelevant---the real solution lies in a well-designed hybrid that leverages the strengths of both. |
