How to Read the Data of UHF RFID Large Capacity User Area

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 Sequence.performSequence” ASYNC API multiple times (recommended this way - good performance)


If 128 words is unstable, you can read 64 words, 32 words or less each time, and the number of calls increases accordingly. The read and write performance of different UHF RFID reader is different. According to the actual test, the amount of read and write data of a single sequence is adjusted; the number of calls is increased accordingly.

Public Hospital in Zhejiang Accelerates the Upgrade of RFID Material Management Solutions

A few days ago, the General Office of the Zhejiang Provincial Government released the "Implementation Plan for Promoting the High-Quality Development of Public Hospitals in Zhejiang Province", which clearly stated that "the operation mode has shifted from extensive management to refined management" and "doing reasonable use of medicines, monitoring of medical consumables and medical core data”, which put forward new requirements for the management mode of consumables in public hospitals. In 2019, the First Affiliated Hospital of Zhejiang University College of Medicine introduced the SPD model for hospital ma terial management . The "smart update" was carried out on the previous SPD model. The hospital fully combined the latest technological means such as the Internet of Things, robots, artificial intelligence, big data, and image recognition to create a new "IF-SPD" model. The overall construction of "IF-SPD" inc

RFID technology escorts the "2022 Beijing Winter Olympics Washing Guarantee Service"!

The washing guarantee service for the 2022 Winter Olympics is a large-scale intelligent service system that is centered on the washing of public textiles such as hotels and hospitals, and integrates linen leasing, washing services, and logistics and distribution. In order to successfully complete the washing guarantee work of the Winter Olympics, RFID technology is used in the whole process of linen procurement, collection, washing, sorting and distribution, helping customers to control the quality of the washing process, check the output port, and ensure the output of textiles is 100% qualified. Use RFID tags to give each linen a unique RFID digital identity, and then use UHF RFID reader equipment to collect the status information of the linen in each handover link and each washing process in real time; relying on powerful data analysis tools and automatic identification and data collection systems , it can manage the whole process and life cycle of linen, thereby
