The Advantages of The Core of RFID Tags Technology in The Field of Fixed Asset Management

RFID tags are an important part of the Internet of Things. Using RFID tags, items and fixed assets can be managed quickly, easily and conveniently, saving time and effort. In the RFID fixed asset management system, what is the core?

The core of RFID tags

1. Chip: The technology and quality of the chip determine whether the entire RFID fixed asset management system can operate normally. RFID chips are divided into tag chips and reader chips. The chip of the RFID electronic tag integrates all circuits except the tag antenna and matching line, including modules such as RF front-end, analog front-end, digital baseband and memory unit.

The basic requirements for chips are light, thin, small, high stability and low price. The development trend of RFID chip design and manufacturing technology will continue to be lower power consumption, longer distance, faster read and write speed, higher reliability and security, and continuous reduction of cost. For domestic RFID chip manufacturers, the most important thing is stability, including the production process that needs to be improved.

2. Antenna: Antenna is also divided into tag antenna and reader antenna. As the carrier of signal transmission, the importance of antenna is self-evident.

In RFID tag technology, the antenna must meet the following points: it has omnidirectional or hemispherical coverage directionality; the volume is small enough to be attached to the item; the chip that provides the maximum possible signal to the tag; no matter what direction the item is, the antenna The polarization can match the interrogation signal of the reader.

The advantages of RFID technology in the field of fixed asset management

1. No need to find the location and read in batches: In reading RFID tags, there is no need to find and scan them one by one like barcodes and QR codes. RFID inventory machine can refer to reading RFID electronic tags, which can read hundreds or even thousands of tags at a time, which is convenient and fast.

2. More content can be read and written, not limited by the size of the tag: RFID electronic tags can store more information, such as units, departments, names, responsible persons, etc., and can also be rewritten and reused repeatedly, with strong tolerance. The read data is also uploaded to the system immediately for processing, and the product can be traced back to its source.

3. Long reading distance: RFID tags are in the inventory. According to the power of the RFID reader and the gain rate of the antenna, the reading distance can range from tens of centimeters to several meters.

4. Long storage period: RFID tags are classified into various categories. According to the needs of users, RFID electronic tags with the characteristics of waterproof, anti-magnetic, anti-corrosion, and high temperature resistance can be selected. Compared with ordinary barcode tags, they are less likely to be damaged and the storage period long.

5. High security: One of the core technologies of RFID tags is the chip, which is not easy to counterfeit, has a reliable security encryption mechanism, and has high security performance.

6. Unique identification: When each RFID tag is printed, the tag has been bound with the item information. For each item, RFID is unique like an ID card.

RFID Technology Improves The Efficiency of Warehouse Inventory Counting

The storage point in the warehouse will greatly save manpower and time, and improve the management efficiency. The automatic collection of RFID technology can more effectively realize quality supervision, so as to track the logistics of the whole inventory in the whole process, realize rapid and accurate inventory counting, and improve the overall transparency of enterprise logistics. Realize the informatization, scientization and accuracy of warehousing management. According to statistics, RFID tag is 600 times faster than traditional one-dimensional bar code software. Staff can easily experience the fluency of instant response and bid farewell to mancadon. Secondly, the performance is stable and the data is accurate. The accuracy of RFID is as high as 99.8%, which is far beyond the level of peers. This is where traditional management software cannot compare with it. Thirdly, the system covers a wide range, which can save labor costs for enterprises. With RFID tag, many warehouse per...

Inventory Solution of Asset Management System Based on RFID Technology

The traditional asset management mode can no longer meet the needs of modern management. Many enterprises and institutions use the asset management system platform to establish efficient and convenient asset management methods. The functions of the RFID technologies asset management system platform cover all physical asset management business activities of enterprises and institutions, including fixed asset increase, asset change management, asset disposal management, equipment maintenance, raw data sorting and import, asset inventory, report data and data exchange, query, asset tracking, statistical analysis and other functions. 1. Time and labor consumption of inventory The inventory is large, the counting process is cumbersome, the accuracy of counting is low, and the source cannot be traced. Manual statistics are prone to errors, which is time-consuming and laborious. Asset management system platform solution: Based on RFID technology, the platform issues inventory operation comma...

Composition of RFID Intelligent Warehouse Management System

In RFID backscatter coupling mode, the frequency of electromagnetic wave reflected by a target is determined by the reflection cross section. The size of the reflection cross section is related to a series of parameters, such as the size, shape and material of the target, the wavelength and polarization direction of the electromagnetic wave, etc. Since the reflection performance of the target usually increases with the increase of frequency, the RFID backscatter coupling mode adopts ultra-high frequency, and the distance between the transponder and the reader is greater than 1m. Small RFID Reader/writer , transponder (Passive RFID Tag) and antenna constitute a transceiver communication system. At present, it is widely used in international container transportation, which not only helps to improve the cargo operation efficiency under the background of globalization, but also improves the security to a certain extent. The application of radio frequency identification (RFID) can fundament...
