RFID Readers

GAOTek RFID readers are network connected devices in which mobile or a fixed base instrument sends data or power and communicates to the tags or transponders through wireless means. It has its own antenna to emit its own unique signal and receive signals from the transponders within range. Our readers can differ from one another depending on its processor, storage, and the radio frequency it operates. GAOTek high-performance RFID readers are reliable, high in quality, and inexpensive equipment that provide progressive experience for easier every day work. It is user-friendly, easy to carry and portable to allow the user to work in complex conditions, which is ideal for new users.


An RFID reader, also known as an interrogator, is a device that offers a connection between the tag and the system that needs the information within the tag. The reader communicates with tags that are within its field of operation, performing any number of tasks including exchanging data live at varying intervals.

The reader has an attached antenna that captures the data from tags. Then it passes the data to a computer for processing. Readers can be a stationary device or integrated into a mobile device.

GAOTek RFID readers and the antennas work together to read tags. The reader antennas convert the electrical current into electromagnetic waves then it radiates into space where they can be received by a tag antenna and converted back to electrical current; just like tag antennas, there are large varieties of reader antennas and antenna selection varies depending on the specific application and environment.

The two most common antenna types are linear and circular polarized antennas. Antennas that radiate a linear electric field have long ranges and emit high power that enables their signals to penetrate through different materials which allow the tags to receive the signal. Linear antennas are sensitive to signals that tags emit depending on the tag angle or placement, though linear antennas can have a difficult time reading tags. Conversely, antennas that radiate circular fields are less sensitive to signals, but are not able to deliver as much power across distances as linear antennas are able to.

The choice of antenna is also determined by the distance between the RFID reader and the tags that it needs to read. The distance is portrayed as the reading range. Reader antennas operate in either a short range or long range. In a short-range application where the read range is less than 30 cm, the antenna uses magnetic coupling so the reader and tag can transfer power. In a short-range system, the readability of the tags is not affected by the presence of dielectrics.

In a long-range application where the range between the tag and reader is greater than 30 cm, long-range antennas will utilize electromagnetic coupling and dielectrics can weaken communication between the reader and tags.


GAOTek RFID readers are reliable, accurate, and easy to use to help prevent failure in operations. They also have the following features available:

l  Operational guide is included to help user start using the meter

l  Can connect to PC via USB connection for networking, printing, weigh scale measurements and data transfer capabilities

l  Multi-mode power scheme (battery, power adapter, computer’s USB port)

l  Microprocessor-based chip and parts apparatus are jointed with SMT technology offers high performance and stability


RFID technology is now extensively used today in many industries of the world; here are some of the new and old industries that incorporate RFID technology into their everyday processes:

Agriculture, Forestry, and Fisheries: RFID is used to track for basic security, as well as it is also used to monitor and manage unique fish, plants, and trees. This increases the efficiency and the production process; the end results correlate with a higher quality of products.

Airline and Airport: RFID are used to monitor and count the passengers boarding the flight; the passenger’s unique identification data is saved in the RFID tag and the readers send it to the server’s database where each information of each passenger is stored. This allows for more security concerning access and tracking.

Cleaning and Maintenance Industries: These industries depend on providing a high level of service to its clients where RFID are used to track the equipment or tools they use and it is used to manage the personnel to have a better understanding of labor performance and its operation efficiencies.

Government and Military: The Border and Immigration Security, Supply Chains and State of Local Agencies requires the use of RFID for accurate inventory reporting, visibility capability, and being able to provide an accurate identification of the assets and personnel. Files and documents, identifications, and licenses are monitored to be managed efficiently, which proves to increase productivity and reduce time consumption. 

Retail: A main user of the RFID technology, the retail industry covers sectors such as automobile dealers, department stores, grocery stores, clothing stores, accessories stores, and car rentals. All sectors share common priorities of customer service in which the use of advanced inventory tracking and enhanced customer experience are the keys to success.
