UHF RFID Reader,RFID Scanner,Handheld Terminal,RFID System Solution

When using the existing RFID Demo software , the length of the read operation cannot exceed 255 words, which is 510 bytes. This is also the upper limit of the amount of data read by Gen2. Reading too much data at a time will also cause the performance of the reading to be unstable. In fact, reading 128 words at a time is not stable. This is related to the performance of the specific label. When actually doing the project, it should be sufficient. After testing, choose an appropriate value as the number of single reads and writes. There are a lot of UHF RFID tags in the user area, such as 1K bytes, how to read the large-capacity data area? There are two ways to read 1K bytes of data as an example: Call the readWait SYNC API 4 times, reading 128 words each time; ReadWait offset=0, size=128 words; ReadWait offset=128, size=128 words; ReadWait offset=256, size=128 words; ReadWait offset=384, size=128 words; Call the “Actions.TagAccess.Operation Sequenc...

By putting the license plate number of the transport vehicle into the RFID electronic tag, when the transport vehicle enters various transport nodes such as intersections, unloading yards, yards, warehouses, etc., it can be carried out by an RFID card reader installed above the road. Reading, completely out of manual intervention, improves the speed and accuracy of vehicle traffic counting. Compared with the license plate recognition technology of video and image processing, RFID-based vehicle recognition has high accuracy and is not easily affected by the environment, and can accurately and comprehensively acquire vehicle information. The electronic tag is pre-written with the basic information of the vehicle through the card issuing management system, such as the vehicle ID, the license plate number, the owner, the fleet, and the like. The RFID tags are installed on the vehicle windshield of all the entrances and exits, and the vehicle has a unique ID card. T...

From the perspective of technological development, high-frequency technology is relatively mature than UHF technology. Through continuous improvement and improvement, a learning curve model for high-frequency tag production, data protocol sharing, and the basis for constructing RFID applications has also been established. Both high frequency and ultra high frequency RFID systems rely heavily on the communication environment between the RFID reader and the tag. UHF uses the principle of electromagnetic emission and is therefore more susceptible to electromagnetic interference. At the same time, the metal will reflect the signal, and the water will absorb the signal, all of which will interfere with the normal function of the tag. The International Organization for Standardization/International Electrotechnical Commission established the ISO/IEC, 15693 standard in 1999 to regulate the implementation of high frequency radio frequency identification technology. Th...

Radio Frequency Identification (RFID) is a non-contact, automatic identification technology. The car security anti-theft system uses radio frequency identification technology to automatically identify the target object and obtain relevant data through the radio frequency signal. RFID technology uses RF transmission to read chip data through external materials for non-contact operation. Communication data uses an encryption algorithm to encrypt data for secure data storage, management, and communication. With the rapid development of electronic technology, the integration of electronic chips has increased, and the cost of RFID systems has been continuously reduced, accelerating the promotion and application of intelligence in the automotive electronics industry. Taking a four-tire car as an example, the system consists of four tire modules, one RFID reader module and one base station module. The base station module includes an RF receiver, an LF transceiver, a ce...

The personal multi-modal biometrics recognition system mainly collects fingerprints, facial images and DNA, and text information into the microprocessor through computer terminals, and then integrates the information into the background and records the individual biometric information database management system through the network. And can be related to other military information about military information, political information, medical care, clothing, wages, housing and other supply relationship information. At the same time, a unique ID serial number is generated and written into the RFID card by the RFID reader and its biometric auxiliary information. Then, only the RFID reader writer is used to read the ID and the biometric auxiliary information, and after inputting into the computer terminal, the matching query is performed in the individual biometric information database via the wireless communication network or the local area network. The computer t...

Based on a simple RFID system , combined with existing network technology, database technology, middleware technology, etc., build a "Internet of Things" consisting of a large number of networked readers and numerous mobile tags, which are larger than Internet. ) has become a trend in the development of RFID technology. The logistics warehousing management system uses RFID technology to capture information, connects it to an open network system through wireless data communication and other technologies, and automatically identifies and tracks the information in each link of the supply chain, thereby building a huge logistics system. A highly intelligent, physical Internet that covers everything between the items on the warehouse and even between objects and people. The RFID-based Internet of Things will fundamentally change the management level of flow monitoring for all aspects of production, transportation, and warehousing within the scope of global l...
