FAQ
  • RFID reader FAQ
    1. What is RFID UHF radio frequency identification technology
    The whole system includes: hardware (data collection and identification) + software (data logic judgment and application presentation), an integrated system RFID ultra-high frequency identification technology, which is a set of identification and collection technology that supports multiple data and long-distance. A non-contact and fast reading technology of multi-label information. To put it simply, when the RFID tag enters the sensing range of the antenna, the reader will collect and analyze data according to the sensed tag, and we finally meet the requirements of practical application through the analysis of the background software system through the collected data.

    What is the role of RFID reader?
    1. Communicate with the tag, under certain technical conditions, communicate with the tag. 2. Communicate with the computer or the system through various interfaces (RS232, TCP/IP), and communicate with the computer. 3. The reading head is basically composed of control software (responsible for communicating with the computer or system), importing software (starting the reading head), decoder (processing the code) and high-frequency interface (receiving and sending codes).

    Classification of UHF RFID readers?
    RFID readers are divided in terms of radio frequency: low-frequency readers, high-frequency readers, ultra-high-frequency readers, dual-frequency readers, 433MHz active readers, microwave active readers, etc. However, the more common applications are mainly UHF readers, which can be widely used in intelligent manufacturing and supply chain, digital warehouse management, production line management, asset management, logistics management and other fields.

    UHF readers are divided into the following categories:
    1. Ultra-high-end desktop card issuer
    2. UHF split-type fixed reader:
    3. Ultra-high Frequency integrated reader
    4. UHF handheld reader
    5. UHF industrial embedded reader

  • RFID Antenna FAQ
    What is the main function of RFID antenna?
    Mainly transmit and receive radio frequency signals
    Technical parameters of RFID antenna
    Gain: refers to the magnification of the sending and receiving signals. Generally, the higher the gain, the farther the distance of reading and writing tags; the stronger the directionality; and the larger the volume of the antenna. The optional range is between 5dBi~15dBi. Standing wave ratio: refers to the reflection of the antenna on the transmitted signal, the smaller the better. Generally, it should be less than 1.2. Polarization direction: refers to the relationship between the electric field vector of the electromagnetic wave emitted by the antenna and the ground, and there are two kinds of linear polarization and circular polarization. There are two types of linear polarization: horizontal polarization and vertical polarization. Beam Width: Refers to the radiation range of electromagnetic waves emitted by the antenna. The smaller the antenna size, the larger the angle.

  • RFID Labels&Tags FAQ
    Frequency band classification of RFID tags? How to divide UHF electronic tags?
    According to the working frequency of the tag, it is divided into: low frequency, representative frequency 125KHz Reading distance: <60CM
    High frequency, representative frequency 13.56MHz Reading distance: 10-200CM
    UHF, representative frequency 860-925MHz Reading distance: 10-300CM

    The memory of EPC Gen2 UHF electronic tag is divided into four areas (Memory Bank):
    1. EPC area (EPC): The area for storing EPC codes, generally storing 96Bits EPC codes, which can be read and written. 2. TID area (TID): store the ID number set by the label manufacturer, generally store 96Bits data, readable but not writable.
    3. User area (User): This area is different for different manufacturers and can be read and written. 4. Reserved area (Password): There are 32Bits access (access) password and 32Bits destruction (kil) password, readable and writable; the first 32Bits is the destruction (Kil) password, and the last 32Bits is the access (access) password.

    Advantages and disadvantages of RFID electronic tags? How to classify RFID electronic tags?
    Advantages of RFID: 1) No need for batteries 2) Not afraid of dirt 3) Not afraid of rain 4) Not afraid of sunlight 5) Strong penetrating power to non-metal and non-liquid materials
    Disadvantages of RFID: Leave the metal as far as possible, and the metal will change the range of reading data.

    3. How are RFID antennas classified?
    1). Classification by frequency band: low frequency RFID antenna, high frequency RFID antenna, ultra high frequency RFID antenna
    2). Classified by antenna form: microstrip antenna, dipole antenna, picofarad antenna
    3). Classification by directionality: directional antenna, omnidirectional antenna
    4). Classified by usage: handheld antenna, split antenna
    5). Classified by polarization: linearly polarized antenna, circularly polarized antenna
    6). Classification by beam width: narrow beam antenna, wide beam antenna
    7). Classification by antenna field distribution: near-field antenna, far-field antenna

  • RFID System Integration Questions
    Q: What is the primary benefit of integrating RFID into our inventory system?
    A:** RFID integration offers real-time tracking and automated inventory updates, reducing human error and improving operational efficiency.

    Q: What are the main costs associated with RFID system integration?**
    A:** Costs include the purchase of tags, readers, and software.

    Q: Can RFID replace our current barcode system entirely?
    A:** RFID can complement or replace barcode systems, especially for high-traffic inventory, but a phased approach is often recommended to evaluate benefits and ROI.

    Q: How do we handle data privacy and security with RFID?
    A:** Implement encryption for TID data transmission, access controls for the RFID system, and regular security audits to protect sensitive information.
