RFID reader, also
known as “RFID reader-writer”, refers to radio frequency identification device
that is used to automatically identify targets and gain related data through
radio frequency signal. That is to say, RFID reader can automatically identify
fast moving objects and recognize multiple RFID tags without human
intervention. In general, RFID reader can be designed as fixed and handheld
shape, including low frequency, high frequency, ultra high frequency, active
and so on. Of late, as a leading professional RFID products manufacturer, DAILY
RFID has also released a bran-new handheld RFID reader DL710Plus and gives the
detailed description about the definition of RFID reader.
The Definition of RFID Reader
The basic
principle of RFID reader is to use RF signals and spatial coupling (inductive
or elecrtomagnetic coupling) or utilize the transmission characteristics of
radar reflectivity to realize the automatic recognition.
Usually, a
typical RFID reader contains an RFID module (transmitter and receiver), control
unit and reader antenna. Via antenna, RFID reader can achieve reading and
writing operations for tag identification code and memory data via the wireless
communication with RFID tag.
In RFID system,
electronic tag is also known as radio frequency tag, transponder or data
carrier; reader is also named as reading device, scanner, communication
equipment, reader-writer (depending on whether the wireless tag data can be
written). Meanwhile, in the coupling channel, according to the timing
relations, the data can be transmitted and exchanged between electronic tag and
RFID reader.

Seven Elements of Selecting RFID Reader
As an essential
part of application system, it is that the model selection of RFID reader is
right or wrong matters to the smooth implementation of customers’ projects and
the implementation cost. Hence, in the aspect of reader selection, users might
be better off passing the rigorous process to ensure the success of projects.
1.
Need
to focus on the frequency range of RFID reader to see if it meets the frequency
specification of the project.
2.
Understand
the largest transmitting power of RFID reader and see whether its antenna has
excessive radiation.
3.
Inspect
the antenna port number that RFID reader has, and decide whether to need the
multi-interface reader according to practical applictaion.
4.
Make
sure the communication interface can satisfy the requirements of project.
5.
Seize
the reading distance and anti-collision indicators. Specifically speaking,
users must know that reading range index is tested under what kind of antennas
and tags; and the anti-collision indicators mean that how long it takes that what
type of tags can be entirely read in what way.
6.
In
addition to the relation with reader, an RFID application system is also
related to tag, antenna, material of tagged objects, moving speed of tagged
objects and surrounding environments, etc. Before the reader is determined,
it’s better off testing and verifying by simulating field condition to
guarantee the product can really cater for the application needs.
7.
Under
the simulated case, please continuously test the stability of the equipment to
ensure it can work stably for a long time.
But then again,
RFID reader DL710Plus is an industry-level handheld terminal developed,
designed and produced based on features of different industries by DAILY RFID.
Available in 125KHz or 13.56MHz working frequency, DL710Plus is perfect for
apparel industry, FMCG field, retail, supply chains, logistics industry, asset
inventory control and other RFID applications.
DAILY RFID CO., LIMITED (http://www.RFID-in-China.com), which
belongs to PAN Group Co., Ltd, is the leading company focusing on the research
and development of EPC & RFID technology. Daily’s RFID readers are designed and manufactured with recognized
industry standards relevant to RFID and its markets but most notably for use in
the demanding environments to recognize and understand your business’s RFID and
NFC needs.
