How do RFID tags work?
RFID tag technology uses radio waves to send information between a tag and a reader. Every RFID tag has two parts:
a microchip that stores data like a product ID, and
an antenna that sends this data to the RFID reader.
When the reader sends out a signal, the tag picks it up. Then, the tag quickly sends back its stored data. This happens in milliseconds, making it possible to scan many items at once, even from a distance.
There are two main types of RFID tags:
Passive tags: These have no battery. They use energy from the reader’s signal to work. They’re low-cost and best for short-range use, like in retail stores.
Active tags: These have a built-in battery, so they can send signals over much longer distances. They’re used to track bigger items like containers, vehicles, or pallets in a warehouse.
RFID tag technology works well in different places — stores, warehouses, and even outdoors. It connects with inventory systems to show real-time stock levels, help plan reordering, and prevent stockouts or overstocking. This means businesses can make faster, smarter decisions and run their operations more smoothly.
Types of RFID tags
RFID tag technology is available in three main types: passive, active, and semi-passive. Each type is designed for different tracking scenarios and business needs.
Passive RFID Tags
Passive RFID tags are the most widely used type. These tags do not have an internal power source. Instead, they rely on energy from the RFID reader to activate and transmit their data.
Key characteristics:
Low-cost and widely available
Suitable for tracking items in retail, supply chain, and inventory environments
Typically used in short-range applications (up to 10 meters)
Ideal for assets that are frequently scanned or located close to readers
Active RFID Tags
Active RFID tags come with a built-in battery, allowing them to send signals independently, without needing a nearby reader to activate them. This makes them suitable for long-range tracking and frequent updates.
Key characteristics:
Battery-powered for continuous or interval-based broadcasting
Capable of tracking over large distances (often 100 meters or more)
Used for high-value assets such as vehicles, shipping containers, and machinery
Higher cost, but highly effective for real-time asset monitoring
Semi-Passive RFID Tags
Semi-passive RFID tags, also known as battery-assisted passive (BAP) tags, are a hybrid of passive and active types. They use a battery to power internal components (such as sensors) but still require a reader signal to transmit data.
Key characteristics:
Offers a greater read range than passive tags, though not as far as active tags
Commonly used for monitoring temperature, humidity, or other environmental conditions
Balanced pricing — more affordable than active tags, more functional than passive ones
Ideal for cold chain logistics, pharmaceuticals, and perishable goods tracking
Choosing the Right RFID Tag
Selecting the appropriate type of RFID tag technology depends on your specific application:
For short-range, cost-sensitive needs, passive tags are a smart choice.
For long-distance and real-time tracking, active tags provide the best performance.
For sensor-based tracking with moderate range, semi-passive tags offer an effective middle ground.
