RFID (Radio Frequency Identification), also known as radio frequency identification, is a communication technology that uses radio signals to identify specific targets and read or write related data without requiring mechanical or optical contact between the system and the target. This non-contact method allows for efficient and automated data exchange, making it a powerful tool in various industries.
RFID technology is widely used across different sectors. For example, in manufacturing, attaching RFID tags to cars on the production line helps factories track their progress efficiently. Similarly, RFID can be used on livestock and pets for accurate identification, ensuring that each animal has a unique identity. In workplaces, RFID-enabled ID cards allow employees to access restricted areas, while RF transponders on vehicles help collect tolls and parking fees.
**The Internet of Things Linker: RFID**
At the core of the Internet of Things (IoT) lies the concept of "Internet of Everything," which focuses on enhancing user experience by collecting and transmitting data more intelligently. Sensors form the backbone of IoT systems, and RFID plays a key role in this ecosystem.
RFID can be categorized into passive and active types. Passive RFID, along with barcodes, was foundational in early RFID development, enabling object identification and data interaction. Since the 1940s, passive RFID has matured significantly, offering small size and low cost. However, its limitations—such as short transmission range, limited data capacity, and reliance on signal reception—have become increasingly apparent in the era of smart technology.
As a result, active RFID has emerged as a promising alternative. Active RFID tags can transmit signals over longer distances and are more reliable, but they still face challenges in terms of power consumption, cost, and reliability.
One company that has successfully entered the active RFID space is Guangzhou Zhongzhi Internet of Things Technology Co., Ltd., established in 2014. With over 80% of its workforce being technical professionals, the company was recognized as a “National High-Tech Enterprise†in 2016.
**Active RFID: Solving Key Challenges**
Compared to passive RFID, active RFID addresses several pain points, such as improved signal reception and extended transmission distance. However, to be widely adopted, active RFID must overcome three major challenges: low power consumption, low cost, and high reliability.
Achieving the “2+1†principle—low cost, low power consumption, and high reliability—is no easy task. Many companies struggle to balance these factors, often compromising on quality or stability. Zhongzhi, however, has focused on innovation, using advanced algorithms tailored to different application scenarios to ensure the best solution for each use case.
**All-in-One Solutions**
Zhongzhi’s RFID-based asset management system is one of the most critical applications for intelligent transformation. For instance, in office buildings, RFID tags enable real-time tracking of instruments and equipment. Through a backend system, users can monitor the exact location of items, set up electronic fences for anti-theft, and automate inventory processes, reducing losses and improving efficiency.
To meet the demands of diverse applications, Zhongzhi adopts a strategic alliance approach from supply chain to end-user. By investing in R&D and delivering strong technical support, the company builds long-term relationships with customers, ensuring sustainable growth through cost-effective solutions.
**Intelligent Internet of Things**
Zhongzhi specializes in RFID positioning technologies, including low-frequency, SUB-1G, and 2.4G solutions. The company primarily focuses on active RFID, complemented by passive RFID, and targets four traditional industries: clothing, food, housing, and transportation.
In the clothing industry, Zhongzhi offers a comprehensive smart solution, covering product management, smart production, warehouse operations, store management, and C2B interactions. In the food sector, the company develops IoT applications such as customer positioning and food delivery. For indoor positioning, Zhongzhi applies innovative techniques to achieve low-power, low-cost, and high-reliability solutions, such as tracking valuables and analyzing personnel behavior.
For outdoor applications, Zhongzhi integrates cellular network technology with its “2+1†positioning system, enabling smart city solutions that go beyond traditional constraints.
**Deep Industry Roots**
Zhongzhi’s focused strategy has led to significant success. In 2017, the company and its subsidiaries achieved impressive results, doubling revenue from 2016 to over 23 million. It established a subsidiary specializing in smart apparel, collaborated with over 30 international food and beverage brands, and signed 25 cities for smart city projects with 20,000 online base stations and 2 million IoT connections. Daily data interactions exceeded 200 million.
Looking ahead, Zhongzhi plans to deepen its focus on the “clothing, food, housing, and PDA†industries, expand strategic alliances, and continue innovating in IoT applications. The goal is to build an industry-focused, tech-integrated, and resource-collaborative IoT ecosystem.
