DAILY RFID Gives the Detailed Description about RFID Reader Definition

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, and 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 electromagnetic 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.

The Function of RFID Reader

1. Reading and writing among different RFID channels
2. Wi-Fi/GPRS/Bluetooth wireless data transmission
3. Integrated GPS positioning
4. Camera with 2 million/3 million pixels and fill light
5. Supporting barcode scanning
6. Bluetooth V2.1 + EDR
7. Wi-Fi WLAN: 802.11 b/g

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.
