Active
An internal battery powers active RFID tags, constantly transmitting signals over long distances. These tags are suitable for real-time tracking of high-value assets, such as shipping containers, vehicles, and equipment, where extended read ranges and frequent updates are essential.
Due to their enhanced visibility and monitoring capabilities, active RFID tags are common in logistics, transportation, and supply chain processes.
Passive
Passive RFID tags do not have an internal power source and rely on RFID reader signals for activation. These tags are more cost-effective than their active counterparts and are also compact.
Passive tags are ideal for scenarios where frequent battery replacement or maintenance is impractical, such as for products in a retail store or entry control like access cards. Their simplicity and affordability make them a preferred choice for various industries, offering reliable and efficient item identification.
Semi-active
Semi-active RFID tags, also known as battery-assisted passive (BAP) tags, balance the abilities of active and passive devices. These tags use a small battery to power the chip but need readers to communicate the information they contain.
Being a cross of two types means enhancing read range and reliability while maintaining a more extended operational life than fully active tags.
Semi-active tags are well-suited for healthcare and food product transportation applications like temperature monitoring. Some companies can also use them for tracking environmental conditions such as humidity.
Types of RFID Systems
As there are different types of RFID tags, so are there various types of systems. Each is distinct in what they can offer and their applications. These are:
Low-frequency
Low-frequency RFID systems operate in the frequency range of 30 kHz to 300 kHz. They employ inductive coupling between the RFID reader and the tag, making them less susceptible to interference from liquids and metals.
This system is for short-range applications such as access control and animal tracking. The architecture includes a reader emitting an electromagnetic field, which powers the LF tags in proximity (around 3-5 feet), transmitting the data.
However, remember that it is very difficult for low-frequency systems to read several tags simultaneously as they have little to no anti-collision properties.
High-frequency
This RFID system utilizes electromagnetic coupling for communication between the reader and the tag and functions in 3 MHz to 30 MHz frequencies. Its read range is shorter than LF RFID, at only 1-3 feet.
One notable application of high-frequency RFID is contactless smart cards, providing a convenient and secure method for electronic payments and ticketing systems, allowing for seamless public transportation or event transactions.
UHF
Also known as ultra-high-frequency, RFIDs that use this structure have frequencies of 860 MHz to 960 MHz, yielding longer read ranges (up to 30 feet) than the previous two types. Due to the speed of information transfer, UHF excels in handling large volumes of tagged items for industries relying on retail inventory management or warehouse logistics.
Microwave
Boasting a read range of up to 300 feet and operating at frequencies above 2.4 GHz, microwave RFID systems have the highest data transfer rate.
Microwave RFID’s higher frequency and faster data transfer rates contribute to increased precision in tracking so that tags transmit information in real-time.
In automotive manufacturing, for instance, companies can employ this system to track vehicles and components throughout the production process for efficient assembly line operations. Another example is the aerospace industry, where teams can use microwave RFID to monitor critical components’ movement within a facility.
