In today’s tech-driven times, you must have seen barcodes or RFID labels on almost every product. Both these cutting-edge technologies have revolutionized the way businesses streamline their operations. But which one among the two is the real winner?
Which one should you choose for your business needs? This blog post is a comprehensive guide wherein you’ll explore both these intricate technologies, their working, and their underlying differences. So, get ready to explore!
What Is RFID Technology? How Does It Work?
Radio Frequency Identification (RFID) is a wireless communication technology in which radio waves are used to automatically identify and track tags attached to objects. In areas such as IoT, RFID proves to be pivotal in increasing the productivity and efficiency of businesses.
From inventory management to user identification and supply chain logistics, it has a wide range of applications. Besides this, you will notice the applications of the technology in almost every field. For example, in the healthcare industry, it’s used in medication tracking, patient and staff identification, and other such tasks.
Now, how does this technology work? In simple terms, each RFID system comprises three components, namely, a transceiver, a transponder and an antenna. The antenna and transceiver can together be referred to as the RFID reader.
The tag (also known as the transponder) itself consists of an integrated circuit and an antenna, which work together to facilitate the data transmission to the reader. To initiate communication, the RFID reader emits a signal that activates the tag.
Upon receiving this signal, the tag utilizes the energy from the reader’s antenna to power its integrated circuit. Subsequently, the tag can transmit digital data back to the reader through its antenna. The tag’s antenna serves a crucial role in both receiving signals from the reader and transmitting data back to it. The stored data within the tag may include a unique identifier or other pertinent information for identification and tracking purposes.
What Is Barcode Technology? How Does It Work?
Barcode technology is another wireless communication technology which involves the use of barcodes. Now, what are barcodes? These are machine-readable codes that contain lots of digital data and are often represented by parallel lines or numbers.
The barcode technology works pretty much similarly to that RFID technology, wherein the chief components are the barcode scanner and the barcode. You must have seen barcodes on every product. Also, you must have noticed store managers using a barcode scanner at the retail checkout point.
The scanner consists of essential components, including a light source, a lens, and a light sensor. These components work together to translate optical signals into electrical signals, making it possible to interpret the barcode.
The scanner emits a beam of light that traverses the barcode. As the light interacts with the code, it reflects in varying patterns and intensities. The scanner effectively captures and converts this reflected light energy into electrical signals. Subsequently, these electrical signals are further processed by the decoder and forwarded to a connected computer or system for further use and interpretation.
Pretty much like the RFID technology, the barcode technology also has a wide range of applications in various fields, including retail, healthcare, manufacturing, and logistics.
Differences between RFID & Barcode Technology
Both these RFID and barcode technologies sound quite similar. They also have similar functioning. This might get you thinking about which one is the best for you and your business needs. Here’s a detailed list of differences between these technologies to help you choose the best one for you.
1. Recognition Principle
Both these technologies are used for identifying and tracking assets and items. However, the basic recognition principle of RFID technology revolves around radio frequency (RF) technology, wherein the radio waves emitted by the reader are used to decode the information stored in the transponder (or the tag). In this technology, you can scan multiple items in one go.
On the contrary, the basic recognition principle of barcode technology revolves around optical (laser) technology wherein the barcode scanner must be in a direct line of sight with the barcode in order to read and decode it properly. In this technology, you can scan only one item at a time.
2. Recognition Range
RFID scanners are effective within a range of 15-300 feet. However, barcode scanners are effective only within a range of 50 feet. Moreover, RFID tags are more accurate than barcodes in adverse conditions.
3. Recognition Speed
RFID technology surpasses barcode technology in recognition speed. RFID tags can be read at a faster rate, with multiple tags read simultaneously. RFID scanning is notably quicker, especially for bulk product movement, processing dozens of tags in a second.
Conversely, barcode scanning requires manual, line-of-sight reading, making it more error-prone and time-consuming. In summary, RFID is more efficient and faster in recognition speed compared to barcodes.
4. Scanning Efficiency
While RFID reads multiple tags simultaneously without line-of-sight, making it faster and ideal for bulk item scanning, barcode tech, though accurate, scans one item at a time. Thus, RFID tags have much higher scanning efficiency than barcodes.
5. Storage Capacity
RFID tags have comparatively higher storage capacity than barcodes. While barcodes have a maximum storage capacity of 3000 characters, RFID tags can store as much as 2 kilobytes.
6. Role of Employees
RFID tags don’t require much manual labor as they can scan multiple items in a single go remotely and simultaneously. However, the barcode reader must be in line of sight with the barcode, which is why employees need to scan each item manually to get the information in the label.
7. Cost
RFID technology is generally more expensive than barcode technology. RFID tags can cost $1 to $30, while barcode labels are just a few cents each. RFID readers are also pricier than barcode scanners.
