RFIDIt is a kind of wireless radio frequency identifies a technology, hand-held is read write implement, it is a kind when identify a technology automatically. Will tell from the concept, RFIDBe similar to bar code scanning, to bar code technology, it is a form that already coded the code adheres to use appropriative scanning to read at target content write implement benefit consumed signal information by form magnetism conveys to be read to scanning write implement; andRFIDUse appropriative RFID to read write implement reach special can adhere to the RFID label at target content, use frequency signal to convey information to be read to RFID by RFID label write implement. RFID applies nowhere to be absent, have research calls RFID the technology or will replace a form code and2 dimension are piled up, present as leading role electronic label develops tide.

RFID technology or will replace a form code and2 dimension are piled up
According to net of couplet of national other people2 dimension are piled upThe explanation that public service platform offers, 2 dimension code is to use body of some kind of specific geometry to press definite pattern to distributing in plane the IT that will record data, compare radio frequency of Yu Yiwei bar code, RFID() wait for a technology, 2 dimension code can bear the weight of inside very small area a large number of information, presswork and know read cost lower, safe and confidential sex is stronger, identify efficiency taller also, have can what ” changes passivity to be active ” is magical.
Actually, 2 dimension code is patulous on the foundation of one dimension bar code give another dimension to spend, use rectangular design to represent binary data, yang Jian disputes an explanation, inside the length of 2 dimension bar code and width limits account a move in chess or a movement in wushu is occupied, can accommodate 1850 uppercase or 2710 numbers or 1108 byte or 500 many Chinese characters, the content tower above that can store than common bar code a few times. Not only such, still can be opposite the information such as picture, sound, character, dactylogram, network address has code. In the meantime, 3 acme that 2 dimension pile up square nod ” as ” fixed position, the machine that read a code locates through differentiating the dot can be read from any direction take identify. And there is one individual test when a lot of users are sweeping 2 dimension to pile up – do not need completely clear alignment, the one share that sweeps 2 dimension code only occasionally even can read news.
“The member that the supermarket receives silver is sweeping commodity when form code, the bar code on the plane such as the box is swept very easily, but for example steamed bread, vegetable is so rough entire article, form code does not have a law to sweep occasionally come out, only procurable use an input, ” Yang Jian of committee member of committee of technology of encode of article of chairman of committee of law of policy of society of business affairs of electron of assistant dean of institute of government of college of Shanghai grain industry, China, whole nation contends for a professor to say, “2 dimension code has very strong fault tolerance capacity, be damaged because of perforative, blemish when 2 dimension code or when the turn is folded, still can know euqally read, even damaged area is achieved 50% also can restore as before. Even damaged area is achieved 50% also can restore as before..
Meanwhile, RFID technology is to rely on the wireless radio frequency in Internet to identify a technology automatically, undertake is not contact, remote, penetrable type, shift identifying to article, make article from production, memory, carry, agency, sell supply chain to consumer each link is tracked by real time, content of self-recording product spreads information, implementation product content sheds information automation, through content shedding at the same time information automation dogs trace to the source, implementation first-rate prevents bogus effect.
RFID technology is had prevent bogus sex absolutely, add secret technology, can no more use, whole journey traces to the source, the advantage such as information control, can reduce labor cost better, improve work efficiency, reduce the investment that prevents bogus to make a holiday, increase product class. RFID technology is the core technology of content couplet net, the gigantic revolution that brings content to shed the Information Industry. The developed country is relying on Internet and RFID technology to build system of network of international content couplet, period of net of international content couplet is coming, RFID label is article enters the identity with indispensable net of international content couplet to identify a shift.
RFID technology applies nowhere to be absent
Passageway management
Passageway management includes personnel and car or article, the personnel that is passageways of pair of pass in and out actually or article are passed identify and affirm, decision whether discharged, have a record, undertake calling the police to permitting the personnel of pass in and out or article at the same time, in order to achieve more close administration, the guard against theft of supermarket of card of our common entrance guard, books management, radio frequency, parking lot that does not collect fees manages a system to wait to belong to passageway management.
Data is collected affirm a system with the identity
Data collects a system is to use the data that contains RFID reader to collect implement the data that collects radio frequency card to go up, or to radio frequency card undertakes reading writing, implementation data is collected and manage, like us commonly used Id identifies the system of card of system, consumptive management system, social security, bank card, check on work attendance collection that belongs to data and management.
Location system
In locating the system is used at automation management, be opposite article of car, personnel, production have fixed position. Reader is placed go up in the car that appoints space, shift, ship or in automation automation line, on the member that radio frequency card is put in mover, article, stock, semi-manufactured goods, finished product, reader joins through the means with wireless wired perhaps means commonly advocate information management system, the system undertakes analytic judging to reading the news that takes radio frequency card, define the position of person or article and other information, achieve automation administration, common application if management of article of management of automation of museum article fixed position, jail staff fixed position, mine staff fixed position, product line, dock.
