RFID is a sophisticated technology used to automatically identify and track objects using radio waves. The term is still unfamiliar to some, especially those unfamiliar with technological changes.
RFID technology is gaining popularity in various sectors, from logistics and manufacturing to healthcare. Besides its efficiency, RFID also simplifies and streamlines many processes that were previously manual and time-consuming.
What is RFID?
Simply put, RFID stands for Radio Frequency Identification. It’s an automatic identification technology that uses radio waves to transfer data between a tag (RFID label) and a reader (RFID reader). The data stored on the tag can include product information, location information, and even a person’s identity.
RFID can operate without direct contact, unlike barcodes, which require manual scanning. In fact, RFID can be read from several meters away, depending on the type and strength. Therefore, many companies are turning to RFID to improve their operational efficiency.
In everyday life, you can find RFID applications in many places. For example, in toll payment systems (e-Toll), employee ID cards, and even warehouse tracking. Very convenient, right?
How RFID Works
Now, let’s get into the technical details. To better understand, let’s discuss how RFID actually works. This technology consists of three main components: an RFID tag, a reader, and a database system.
Before delving into the details of each component, it’s important to understand that all RFID processes are powered by radio waves. This allows the interaction between tag and reader to occur quickly and without physical barriers like cables or direct contact.
RFID Tag
An RFID tag is a small label attached to an object to be tracked or identified. Inside the tag is a small chip and antenna that store and transmit data to a reader. These tags can be active (using their own battery) or passive (without a battery, powered by the reader).
RFID Reader
The reader reads information from the tag using radio waves. The reader sends a signal to the tag, which then responds with the data stored inside. These readers can be used portable or installed in a fixed location.
Database System
After the reader reads the data from the tag, the information is sent to a database system. This is where the data is stored, processed, and used for various purposes, such as stock recording, asset tracking, or identity verification.
Types of RFID Based on Frequency
RFID comes in various types based on their operating frequencies. Each frequency has its advantages and disadvantages depending on the application. Let’s discuss each one individually to make it easier for you to choose if you want to implement it!
1. Low Frequency (LF)
Low-frequency RFID (125-134 kHz) has a short read range, around 10 cm. This type is often used for simple applications such as animal identification or access control. Its advantage is that it is less susceptible to interference from metal or water.
2. High Frequency (HF)
Meanwhile, High Frequency RFID (13.56 MHz) has a better read range, up to 1 meter. This type is commonly used for access cards, electronic tickets, and cashless payments. NFC (Near Field Communication) falls into this category.
3. Ultra High Frequency (UHF)
Then there’s Ultra High Frequency RFID (860-960 MHz), which can read tags from several meters away. Due to its wide range, this type is suitable for inventory management, logistics tracking, and mass distribution of goods.
Advantages of RFID Technology Compared to Barcodes
RFID is a technology often compared to barcodes. While both have similar functions, RFID is clearly superior in several aspects. One of its biggest advantages is speed and ease of identification.
With RFID, you can read multiple tags simultaneously without needing a direct line of sight. This is especially helpful in inventory management or tracking items. Furthermore, RFID tags are more durable and reusable, unlike barcodes, which are easily damaged.
RFID implementation can also reduce data input errors because the process is automated. This minimizes human error and, of course, makes work more efficient.
RFID Applications in Real Life
RFID usage is now increasingly widespread, not only in large industries but also in everyday life. For example, in libraries, RFID helps speed up the process of borrowing and returning books. Furthermore, in hospitals, RFID tags are used for patient tracking and medical equipment.
In the retail and warehousing sectors, RFID is extremely helpful in inventory management. Items entering and leaving the warehouse can be automatically recorded without the need for individual inspection. This significantly saves time and effort.
If you have a business that manages a lot of inventory, RFID can be a practical solution to improve accuracy and efficiency. In fact, there are now RFID-based stock management systems that you can easily utilize.
