RFID Reader

The RFID reader is an automatic identification device that can read the data of
electronic tags. According to the different readings, tag frequency is divided
into low frequency, high frequency, ultra-high frequency reader. RFID reader
needs to be equipped with an RFID antenna to read tag information.

The Principle of RFID Technology
The basic working principle of RFID technology is not complicated: the Tag into
the magnetic field, after receiving the rf signal from the reader, with the
energy gained by the induced current send product information stored in the
chip (Passive Tag, Passive tags or Passive tags), or take the initiative to
send a frequency signal (Active Tag, Active Tag or Active);After reading and
decoding the information, the reader sends it to the central information system
for relevant data processing.
The RFID label reader: The basic information carrier of the measured object is
the electronic RFID card tag, which has two types. The other type is passive,
which has no power source of its own and is supplied by an external power. So
who's going to power it? It's the card reader in the RFID system. It is a radio
frequency transceiver that, once in operation, emits an am signal to activate
the electronic tag. In the case of a passive electronic tag, it has to be
transmitted power. Of course, the transmission of electrical energy is limited
by many external conditions.
Different Types of RFID Readers
Desktop Reader is an ID/ IC reader for both 125KHz and 13.56MHz dual-band.
Adopt advanced plug and play, no-drive USB connection technology. By simulating
the keyboard output mode, the card number of RFID card can be obtained by
swiping card, which is simple and stable. At present, Desktop Reader has been
widely used in data entry, information inquiry, Internet bar registration, book
lending, conference check-in, and access control.
The handhold readers is characterized by its read/ write functions, battery
charging management function, etc. It fulfills the requirements of the
customers for E-commerce application which enables the user to take the
portable to where tagged items to be scanned rather than moving objects to a
reader fixed at certain area.
