RFID technology was previously a major focus across several industries, including retail, logistics, and manufacturing. It provided companies with unprecedented efficiency improvements and management optimization. So, with the rapid advancement of technology, does RFID still have a place in the mainstream? Let’s review the history of RFID, its current application status, and future trends.
Background and Development of RFID
The earliest rise of RFID (radio frequency identification) can be traced back to the 20th century. It is a technology that transmits information through radio waves and is widely used in areas such as commodity tracking, identity recognition, and asset management. With the rapid growth in the early days, various industries have discovered the huge potential of RFID. For example, retailers can effectively manage inventory through RFID, and logistics companies can track goods more accurately. However, as time goes by, people may wonder: How is the development of RFID today? Does it still maintain the glory of the past?
How does RFID technology work?
Let’s first look at how this technology works. A fully functional system includes three primary components: tags, readers, and antennas. First, RFID tags are equipped with microchips that store the unique identification information of items. The reader then transmits radio waves to the tag to retrieve the data stored in it. The antenna acts as a bridge, which is responsible for sending and receiving these wireless signals, allowing the reader to “talk” to the tag.
Compared with traditional barcodes, RFID technology has several significant advantages:
No contact: The reader does not need to be directly aimed at the tag, and can even read information through packaging or obstacles.
Long-distance reading: Depending on the system settings, RFID tags can be identified from a few centimeters to several meters or even farther.
Simultaneous identification of multiple tags: An RFID system can identify multiple tags at the same time, while barcodes need to be scanned one by one.
These characteristics make RFID far superior to traditional barcode systems in speed and efficiency, especially suitable for scenarios that require fast and large-volume processing, such as logistics, warehousing, and retail industries.
Types of RFID tag
Let’s talk about the types of RFID tags. There are active tags and passive tags. Active tags have their batteries and can actively transmit signals, which are suitable for long-distance identification. Passive tags are activated by the energy of the reader, which is lower in cost and more widely used. If you want to know more about the difference between active tags and other tags, you can read this blog. Additionally, RFID tags can be categorized based on their operating frequencies into low frequency, high frequency, and ultra-high frequency. Each type is suitable for different application scenarios. These different frequencies have a great impact on the actual application of tags.
