UHF RFID Reader types and application scenarios


UHF RFID Reader types and application scenarios, and selection techniques



RFID Reader (Radio Frequency Identification abbreviation) also known as "RFID Reader", that is, radio frequency identification, through the radio frequency identification signals to automatically identify the target object and obtain the relevant data without human intervention, can identify high-speed moving objects and can identify multiple RFID Tags at the same time, the operation is fast and convenient.


RFID reader not only can read radio frequency tags, but also can erase and write data, so called read-write. If you can only read, can not be erased, it is called a card reader or RFID Reader. Readers applications are very wide, mainly used in identification, goods identification, security certification and data inclusion, with security, accuracy, speed, expansion, compatibility and other characteristics.


Components of the Reader

A typical reader terminal generally consists of three parts: antenna, RF interface module and logic control module.




RFID Reader from the radio frequency: low-frequency readers, high-frequency readers, UHF readers, dual-frequency readers, 433MHz active readers, microwave active readers and so on. However, the more common applications mainly for UHF Readers. Today, we will enter the wonderful world of UHF Readers to understand!


Types of UHF Readers

I. RFID Desktop Reader


The main function of such readers is to issue cards and RFID Tags data initialization, can be read on the label, write cards, authorization, formatting and other operations, suitable for warehousing, logistics, clothing, production line management and other areas of RFID Card with. Its characteristics: small size, low cost, short reading distance.


2.       RFID fixed readers


Such readers are characterized by RFID Reader module and fixed reader, according to the needs of different application scenarios, configure different reader modules and antennas, commonly used antennas 6DB, 9DB, 12DB, etc., near-field antennas and far-field antennas can be, in addition to read/write there are single-channel, dual-channel, four-channel and eight-channel, up to 32-channel antenna interfaces, which can be widely used in the field of intelligent manufacturing and supply chain, digital warehouse management, commercial retailing, asset management and so on.

3.      RFID Integrated Reader 


The biggest feature of such readers is RFID read/write module and antenna assembled into an integrated reader, with strong anti-jamming ability, excellent protection performance and easy to install and use, cost-effective features, mainly used in license plate anti-counterfeiting identification management, intelligent parking lot management, warehouse materials in and out of the supervision and identification management, airport baggage and parcel identification management, intelligent manufacturing and other fields.


4.       Mobile RFID handhelds Reader(pda)


GZY-202 UHF handheld reader is characterized by mobility and portability, the operating system is mainly Android 10.0 operating system, the interface design is more friendly, RFID read range from 0-15 meters, at the same time can be integrated with wifi, 4G, bluetooth, bar code, two-dimensional code and other functional modules, read and write performance is good or bad with the RFID read/write chip module, built-in antenna has a direct relationship. Adaptation to mobile data collection in indoor and outdoor harsh environments, is the first choice for asset management, inventory, find a variety of applications such as environmental data collection products.


5.  Convenient small read-write


The biggest feature of such products is: low cost, easy to carry, short reading distance, mainly using the smartphone operating system for joint use, operation and use is more convenient. Currently on the market there are three main interfaces: audio port, USB interface, Bluetooth, they have advantages and disadvantages, can be used in different applications above.


USB Interface Reader


Connects to portable front-end data collection devices such as smartphones, PDAs, laptops, printers, handheld terminals, etc. via USB interface.


Bluetooth UHF Reader


It can be connected with ios, android and other intelligent system platforms through Bluetooth interface, and can also be connected with computer through USB. Wristband design, while optional selfie stick accessories can easily become a gadget reader, easy to industrial applications. Can be flexibly adapted to a variety of smart phones, and other smart devices.

6.     Industrial Embedded Reader/ RFID Printer


The characteristics of such read-write: in different work equipment using embedded UHF read-write module, as a data acquisition I / O module, and connected to the industrial control host, to realize the different functions of the equipment applications. The most common lies in the RFID printer, now more and more industrial Internet of Things, intelligent manufacturing, automation equipment using this model.






Selection of UHF readers


1、Business requirements, application scenarios


The choice of UHF Reader, first of all, to meet the business needs, suitable for application scenarios. This is to consider the Readers reading range, speed, and whether the application environment is suitable.



2, CPU, memory capacity

Portable UHF RFID reader memory capacity to determine the data capacity, its memory capacity to correspond to the CPU processing speed. If the use of low performance CPU, blindly increase its memory capacity, will increase the user to use the processing, waiting time.


3. Power consumption and duration


Portable UHF reader is powered by the built-in battery, if the work of a sudden powerlessness, will inevitably reduce the efficiency of the staff. So in the selection of portable UHF readers, we must consider the read-write power consumption and battery life, whether it can meet the actual business needs.



4Protection level


The higher the protection level, the more expensive it is. Higher levels of protection can ensure that portable RFID readers operate stably and efficiently in harsh industry environments. It is especially important to choose a reader that meets the protection level requirements.



5. Reputation and strength of suppliers


Word of mouth is built on product quality and service. When choosing a supplier or manufacturer, you need to fully understand the productivity, innovation, after-sales service and the quality of the product.


6. Price

In addition to considering the hardware price of RFID readers, it is also necessary to consider the cost of development tools, application software development process of hidden costs, as well as maintenance costs after the product is put into use.


Different categories of readers and writers, the price difference is also relatively large. The actual application can be selected according to the application needs.



Here put the price at the end, but also to remind you: the choice of read-write, the premise is to meet your business needs, suitable for your application scenarios, and finally to consider the price.
