Principle and Classification of RFID Handheld Terminal
Firstly, Introduction of RFID technology
RFID is a kind of non-contact automatic recognition technology, it recognizes object and gets data with the radio frequency signal. It is most used in anti-counterfeiting tracing, warehouse material tracing and workshop producing tracing. RFID is made up by three parts, they are label, reader and antenna.
Working frequency of RFID could be divided into LF, HF and UHF. For LF, the frequency is between 30 and 300KHz, 134.2KHz is the most common one. For HF, the frequency is between 3 and 30MHz, 13.56MHz is the most used one. For UHF, the frequency is between 300 and 968MHz, 902-928 MHz is most used scale.
Secondly, Characters of RFID
Thirdly, Introduction of HF and UHF label
Specifications of HF label:
It is an electronic label with 13.56MHz working frequency, such as S50, S70 and 15693 label.
Specification of UHF label:
00 district, also called Reservered district, it has kill password and access password.
01 district, also called EPC district, it has storage EPC number.
02 district, also called TID district, it is storage label recognition.
03 district, also called User district, which is used to store data of users.
Fourthly, Introduction of RFID handheld terminal
RFID handheld terminal supplied by Seuic are AUTOID 9, Cruise 1 and AUTOID PAD. For more accurate information, please search www.chinaautoid.net.
The Last, Skills of RFID reading
It is affected by iron and electromagnetic, it should be operated away of them.
If the label is anti-metal kind, it should be attached on metal, which could keep the long-distance reading.
If the environment is better, it could be tried to raise the read power.
It should understand package material and process, which could be eliminate the package cause of reading performance degradation.
When reading labels, it should pay attention to the environment, try to read the angle and power settings, people should not be too close to the label. The hands should be far as possible to hold the machine on the side, not block the back.
It should understand the number of stacked goods on site and the distance between labels, try to keep all labels in the same direction with regular.
