The Introduction of RFID Handheld Readers
In the passage, we will elaborate the RFID tag and reader. Radio Frequency Identification (RFID) is an automatic identification technology that automatically uses electromagnetic fields to identify and track tags attached to objects. The RFID tag can be identified and analyzed by RFID handheld readers. RFID technology is widely put into practice in multiple industries by virtue of its convenience and easy management. People apply the technology to payment, warehouse management, and retail, etc.
How Does RFID Work?
In the first place, a tiny radio transponder, a radio receiver and a transmitter is inset in the RFID tag. Therefore the RFID tag can transmit signals with these settings. The tag utilizes radio waves to transmit signals; when the chip placed in the tag is activated, the energy is enabled and will send radio waves to the reader. And the RFID handheld reader will interpret these radio waves into helpful information. In general, it is an excellent approach to track and store information.
Three Types of RFID Tags
There are three types of RFID tags and they are active tags, passive tags, and semi-tags.
Among the three types of RFID tags, the earliest and the most mature one is the passive tag, which had no battery. However, low cost and a long service time are the advantages of the passive tag. The active tag functions when the reader scans the tag through a radio wave. When senses the radio wave, the electromagnetic induction coil will produce temporary electricity to transmit. While active tags have the above merits, they only can be read in a short distance. That’s why they are usually applied in close recognition in a short distance.
About the active tags, the batteries are embedded in them. Hence it is of higher manufacturing cost and the service time is shorter than the passive tag. However, it is outstanding for automatically sending signals to the reader to scan and transmitting signals in a long-distance, which provides high efficiency.
The semi-passive tag will be in a state of dormancy when not need to work, while maintaining the part of data with electricity so the data will be kept and costing low electricity. The semi-passive tags are usually placed in an extensive range of places covered with high-frequency signals to activate. And readers can locate its location and then the semi-passive tag can finish the transmission through a high-frequency signal.
The chart distinctly shows the differences among active tag, passive tag and semi-passive tag.
| Types | Battery | Cost | Service time | How to send Signals | Recognition distance |
| Active Tag | With battery | High cost | Short service time | Send signals automatically | Long-distance recognition and precision |
| Passive Tag | No battery | Low cost | Long service time | Produce signals when it is activated by the radio wave sent by the reader. | Short distance recognition |
| Semi-passive tag | Maintain the data part with little electricity | Low cost | Long service time | Low frequency to activate and transmit signals with high frequency. | Long-distance recognition |
RFID Reader
The reader is indispensable when the RFID tags are put into application. Without readers to collect and interpret information, the tags will be useless. Therefore, an excellent reader is of help when you are doing your job. How to select a terrific reader? We are here to provide you a fantastic choice—UROVO DT50U portable RFID scanner (https://en.urovo.com/products/rfid-data/dt50u.html).
The Strengths of the Handheld Reader
So why is the Urovo DT50 handheld reader is your best choice?
First, the Urovo DT50 handheld reader distinguishes itself from others by the high precision RFID recognition. Having a 5dBi high sensitivity antenna enables the reader a more comprehensive range of scanning. And it can read tags in bulk within 20 meters.
Second, its adaptive interference cancellation can accurately identify tags in an environment with heavy-metal interference. Besides, possessing a focused recognition technology makes the handheld reader quickly reduce the block sight and “blind spot”, allowing it smoothly read tags in high density.
Third, RFID smart handheld terminal’s ergonomic handle is designed with the idea of skid resistance and anti-fatigue and that allows you to work more focused and more efficiently. That makes it one of the best portable scanners suitable for users to hold. And users won’t feel exhausted when using it.
Fourth, adopting heat dispersing materials and heat dispersing design technology pairing with the optimization algorithm, the portable RFID reader performs with low power and can disperse heat quickly. All these advantages facilitate it with a longer service time. Therefore, the DT50 handheld reader can scan codes for two hours continuously.
Last but not least, carrying an international professional scan 1D/2D scan module, the scanner can realize scanning codes in high definition, whether they are 1D, 2D, twisted, or stained code.
It is a UHF RFID smart handheld terminal that is efficient in collecting and managing data. Reading RFID tags in bulk within few seconds is what the smart handheld terminal is good at. Equipped with an international professional code scanning module, it can quickly read the international universal 1D or 2D, distorted, stained, or old codes.
Besides, the rugged handheld reader is waterproof and dustproof. Moreover, it has passed the test of a 1.5-meter drop. These virtues prove that the Urovo DT50 handheld reader is one of the best portable scanners perfectly applied to various industries, such as wholesale, jewelry management, retail inventory, asset inventory, warehouse management, etc.
The above advantages can be concluded as below.
UROVO DT50U Portable RFID Scanner：
-Fast scanning with high precision
-Comfortable hand shank
-Waterproof and dustproof, anti-drop
-Functions with low power and it can disperse heat quickly
-It can read codes in bulk
The Application of RFID Reader
The RFID reader can be used in various situations or industries because it can scan barcodes or QR codes within blinks. In particular, in logistics, it can scan and collect the information with high efficiency and manage them in easy operation. People often apply them in wholesale, jewelry and library, and retail inventory, etc.
UROVO DT50U portable RFID scanner is distinguished from other handheld RFID scanners for the above merits we have mentioned. Therefore, if you consider the handheld reader a good buy, please click the following link and purchase if you need the RFID scanner.
