RFID(Radio Frequency Identification)
RFID technology uses radio waves to perceive information from a distance is AIDC (Automatic Identification Data Collection Technology) sectors.
RFID (Radio Frequency Identification) technology uses radio waves to perceive information from a distance is AIDC (Automatic Identification Data Collection Technology) sectors.
RFID is To identify an object, such as information on things.
And this additional information using non-contact wireless communication media are recognized as existing,
you can automate various Application.
Bar-Code are usually marked on the Label information in the visible region using the light by sequential (One by one) to gather information by Scanning.
But there are a number of RFID electronic tags suspended or even in the area of non-visual information in a situation to move quickly and
accurately you can gather by using radio waves.
Also can record information back to the repeated falsification and tampering of information, reusable, and secure.
RFID System
Transponder (Transmitter + Responder, Tag, Electronic tag)
Electronic tags to record the information stored in a tiny integrated circuit (IC) and consists of an antenna transmitting and receiving frequency.
Passive, Active, depending on the power supply
Interrogator (Reader, Antenna)
RFID Reader is One or a number of connecting digital and analog signal Antenna using electronic tags
and information about the song and received.
And this is in order to control the PC connected with communication features.
Middleware
Computer or Server is installed on the RFID Reader control, In addition, you can handle the end of the
received information and analysis of computational devices
to transmit information to the application.
RFID Frequency and Characteristics
RFID systems radio frequency is Lower Frequency(LF, Under 135KHz ) & High Frequency(HF, 13.56MHz) and
Magnetic filed(Induction coupling), Ultra High Frequency(UHF, 333~433MHz, 860~960MHz and Microwave(MW, 2.45GHz)is using Electric filed.
Electromagnetic sensitivity in a dielectric transmission damping phenomenon and, in the case of reflection,
absorption of metal liquid characteristics can cause the disorder.
