Basics of RFID

What is RFID and how does it work?

Radio Frequency Identification, or RFID, refers to a technology where information is transmitted wirelessly over radio waves. It is an automatic identification method that uses radio waves to read and capture information stored on a tag attached to an object.

What are the advantages to RFID?

There are a number of advantages to using RFID technology. Not only are RFID systems contactless, but they also do not require line of sight like other auto ID technologies. For different applications spanning various industries, RFID technologies offer a long-term and durable solutions for better asset management and tracking

What is an RFID system? What's in an RFID system?

RFID systems are made of three main components: tags, readers and middleware.

-Tags are essentially small memory banks, storing bit of valuable information that can be used for asset management and a variety of other purposes. They use radio waves to communicate with nearby readers, sending over portions of identifying data. The information sored in RFID tags can range anywhere from a single serial number to multiple pages of data.

- Readers, on the other hand, are basically the other end of the information exchange. They are what we use to take those radio waves from the tags and translate them back into useful data. Readers are devices with one or more antennas that can emit their own radio waves and scan the signals of any RFID tags within range.

- RFID readers offer some versatility depending on the needs of your application. You can have mobile readers that you can carry around in your hand to scan tags, or they can be mounted in a single location to scan tags that enter their proximity. Readers can even be built into existing architecture like a cabinet or doorway.

- Middleware serves as the essential interface between the reader and your company databases and information management software. Not only does middleware handle communication between the reader and your existing systems, but it also helps to filter, aggregate and interpret all of that data coming from the RFID tags.

What are some advantages of RFID?

- Time Savings - of the most significant operational benefits of RFID technology is the ability to read multiple tags at once, with the option to detect assets upon arrival instantly. Rather than having to scan each barcode individually and line the label up with the scanner, RFID works on proximity, allowing you to read a case lot of containers or pallets in a fraction of the time.

- Reduced Human Error and Low Labor Requirements - Human error is almost eliminated with the intuitive nature of RFID systems. So long as the tags are within range of the reader and there is no outside interference from the environment, RFID technology reliability tracks your assets every time.

- RFID-enabled asset management also requires far less labor than manual or barcode-only checks. Especially with higher-end RFID tags and fixed readers, RFID asset management is the closest thing to a fully automated tracking solution.

- Easy Integration and Updates - RFID can work with many existing systems, allowing you to integrate RFID systems into your supply chain easily. You can also choose to adopt RFID technology at certain locations, to begin with, then add on additional locations at your own pace.

- Durability - depending on the construction of the tags, RFID tags can be extremely durable and withstand exposure to the sun, rain, and other harsh weather conditions. This makes them ideal for various applications, such as asset tracking, stock management, etc.

- Higher Security - RFID technology offers a higher level of security than barcodes, which helps prevent the spread of sensitive information. For example, RFID tags are more difficult to counterfeit than barcodes. This makes them a more secure option for tracking items and protecting against fraud. RFID tags can also be read farther away than barcodes, making them more efficient for tracking large quantities of items. Overall, RFID provides a higher level of security and efficiency than barcodes, making it a better choice for businesses and organizations that must protect their sensitive information.

- Higher ROI - for many applications and use cases, RFID implementation can lead to a significant ROI when properly specified according to the requirements of your application. Environmental constraints, asset compositions, and read range limitations/requirements can impact how effective, and cost-efficient an RFID system is for your application. While RFID is considered the latest and greatest evolution in asset management, it may not be right for every application, especially if you're expecting a certain ROI in a specific time window.
