Radio frequency identification (RFID) is in everything from amusement park passes to payment solutions. This wireless technology allows businesses to automatically identify and track objects, tools, equipment, vehicles, and more.
In recent years, RFID technology has become increasingly popular and has found numerous applications in various industries, including retail, logistics, healthcare, and manufacturing. But how does RFID work, and how can businesses leverage it? Check out this guide to learn what RFID is, how it works, how it differs from other tagging technologies, and the potential benefits of RFID.
RFID is a technology that uses radio waves to transmit data from an RFID tag to a reader that logs the data. The system consists of three main components: an RFID tag, an RFID reader, and a computer system.
A business places an RFID tag on or inside an object, such as a retail product or a piece of industrial machinery. The tag contains a microchip that stores data, as well as an antenna that receives and transmits radio signals.
When an RFID reader emits a radio frequency signal, the tag detects it and responds with the data stored in its memory. The reader then captures the data and sends it to a computer system for processing.
RFID systems can use different frequencies, but the most common include:
RFID tags can be either passive or active. Passive RFID tags don’t have a built-in power source and rely on energy provided by an RFID reader. Active RFID tags, on the other hand, have a built-in power source, such as a battery, and can transmit data on their own without relying on an external power source.
Whether you’re a retailer, a healthcare provider, or a manufacturer, you likely use a mix of different tagging solutions throughout your organization. Barcodes and QR codes are some of the most common options for businesses, but RFID works differently.
Barcodes are a visual tagging technology that uses a series of bars and spaces to represent data. Barcodes are inexpensive and easy to produce, but they require a direct line of sight to a reader and have a limited storage capacity. In contrast, you can read RFID tags from a distance. They also have a much larger storage capacity than barcodes.
QR codes are a two-dimensional visual tagging technology that uses a matrix of dots to represent data. QR codes can store more data than barcodes and can be read using a smartphone camera, but they still require a direct line of sight and aren’t as versatile as RFID tags.
RFID technology has been widely adopted for asset tracking in various industries, including retail, healthcare, logistics, and manufacturing. For example, retailers use RFID tags to track inventory and prevent theft, healthcare providers use RFID wristbands to track patients and medication, logistics companies use RFID to track shipments and optimize supply chain operations, and manufacturers use RFID to track products throughout the production process.
If you’re trying to embrace digital transformation in your business, RFID tags make it much easier to transmit information automatically. RFID technology has numerous benefits, including:
However, keep in mind that durable barcode labels are often a better choice for certain applications. For example, the U.S. military also uses RFID tags for some applications, although for military asset tracking, unique identification (UID) labels are more suitable for security, compliance, and durability requirements.
RFID technology might sound complex, but it’s a simple and easy way for organizations to manage the movement of equipment, products, and other objects. With the right RFID system, organizations can streamline their operations, cut costs, and increase compliance.
