RFID Basics Introduction
1.What is RFID
RFID is the acronym for radio frequency identification. Often referred to as inductive electronic chips or proximity cards, contactless cards, electronic tags, electronic bar codes, and so on.
A complete set of Reader and Transponder RFID system consists of two parts, the action principle on the grounds Reader launch a specific radio frequency energy to the infinite Transponder, Transponder circuit to drive the ID Code will be sent within this time will receive this ID Reader Code. Transponder is a special battery-free, non contact, free credit card it is not afraid of dirt, and the chip can not copy the password is the world's only high security, long life.
RFID is widely used, typical application of the current animal chip, chip car alarm, access control, parking control, automatic production line, material management. There are two RFID tags: active tags and passive tags.

Radio Frequency Identification RFID is a non-contact automatic identification technology, radio frequency signal through the automatic target recognition and access to relevant data, to identify work without human intervention, can work in a variety of harsh environments. RFID technology can identify the high-speed moving objects can also identify multiple tags, the operation quickly and conveniently.
Not afraid of short-range RF products grease, dust, pollution and other harsh environment, this environment can be replaced in the bar code, for example, used in factory assembly line to track objects. Long-range radio frequency products used for transport, recognition distance of up to tens of meters, such as automatic vehicle identification and other charges or identified.
2. What is RFID Tags
There is the RFID tag, said RFID tag, radio frequency identification. It is a non-contact automatic identification technology, target identification through radio frequency signals and to obtain relevant data, identify the work without human intervention, as the wireless version of the bar code, RFID technology has the bar codes do not have waterproof, anti-magnetic, high temperature, long service life, reading from a large, data can be encrypted on the label, a greater capacity to store data, store information changes with ease and so on.
