Share information through thin air with a simple gesture. Radio Frequency Identification (RFID) allows devices to share information without physical contact. This technology has many uses - let's get in and understand what it is, how it works and how to use it.

In this article, I went online and gathered some information about how to use RFID label readers, and I hope you find it helpful. Let's keep reading to learn more.

This passage is going to talk about the followings of RFID labeling:

1) RFID labels and RFID label readers

2) RFID Applications

1) RFID labels and RFID label readers

RFID is similar to other wireless communication technologies, such as radio transmitters, Bluetooth, LoRa, etc. The system consists of two components, the tag and the reader. The tag contains data and the reader detects the tag when it is in range and processes the information in the tag (more on this later). The tag has a small amount of memory to store a unique tag identifier (TID), which is not editable. The small amount of data remaining on the tag can be read-only or writable, depending on how the tag is designed.

2) RFID Applications

No doubt you have seen RFID used in everyday life - for example in security badges. A security badge is an RFID label that contains a unique ID that is scanned by a reader. when the reader detects the badge, the reader will read the tag data, process the data as needed, and then pass the data to an access control system for verification. The system will then determine if the security gate will be unlocked.

Another example is tracking the times of marathon runners. It is relatively easy to track thousands of runners by providing each participant with an RFID label. RFID label readers are located at the start and finish lines so that it is possible to know exactly when each runner starts and finishes the race. Regardless of the application, the technology behind RFID boils down to electromagnetic waves.


How can a tag communicate with a reader without its own power source? This is where the electromagnetic force comes from. Once a passive tag comes within the range of a reader, the tag receives electromagnetic energy from the RFID label reader's antenna. The tag's antenna is a conductive material that, when hit by an electromagnetic wave, induces a current that powers the tag's IC. The tag then "turns on" and begins broadcasting its data. The reader's job is then to interpret the signal received from the tag into usable data.

Passive vs. Active

As mentioned above, RFID labels are capable of harnessing the energy in the reader's electromagnetic field. This is passive RFID. another option is active tags. Active tags are usually self-powered by a battery, which enhances the tag's signal. This allows active tags to have a longer range than passive tags.

Radio frequency is important

Simply having the reader and tag within range of each other does not guarantee that they can communicate. They must also use the correct radio frequency and, if encryption is used, must have the correct key. Regardless of which RFID label reader is used, it must be able to read the carrier frequency of the tag that needs to be read. This information should be available on my product page description or in the data sheet. You can contact us for more information.
