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)

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. The standards for UHF are not so uniform, and the frequencies used in different countries are not the same. The UHF designated by the EU is 865~868MHz, the United States is 902~928MHz, India is 865~867MHz, Australia is 920~926MHz, Japan is 952~954MHz.
The European Telecommunications Standards Institute (ETSI) EN300-220 specification has two main provisions that are less favorable for UHF. One is about the power limitation, which stipulates that the effective radiated power is 500 mW; the second is about the bandwidth limitation, and as a result, the reader cannot be frequency hopped.
