I. Current Industry Landscape
As market competition intensifies, enhancing production efficiency and reducing operational costs have become critical imperatives for enterprises. Currently, most warehouse management systems rely on tools such as barcode labels or manually processed paper documents to facilitate warehouse operations. However, the inherent limitations of barcodes—such as their susceptibility to counterfeiting, poor resistance to dirt and moisture, and complex operational procedures—combined with the complexities involved in manually completing documentation, make these methods highly prone to human error and material loss. Consequently, warehouse management practices within the domestic sector continue to suffer from significant shortcomings.
II. Challenges Currently Being Faced
Today, warehouse management within grain storage facilities and related enterprises still largely relies on non-automated, paper-based record-keeping systems to track the inflow and outflow of grain. The specific challenges encountered include:
(1) **Diversity of Grain Types:** Given the wide variety of grain types, it is common for different categories of grain to be received into storage simultaneously. Similarly, outbound shipments often require individual orders to comprise multiple packages of various grain types. Under these circumstances, relying on manual methods to count incoming and outgoing stock results in an extremely high error rate.
(2) **Inventory Auditing:** During inventory audits, relying on manual verification to cross-check stock quantities leads to similarly high error rates, making it difficult to ensure that physical stock levels accurately match the corresponding ledger records.
(3) **Human Factor Uncertainty:** The inherent uncertainties associated with human involvement result in low operational efficiency and constitute a significant waste of human resources. Furthermore, as grain volumes increase and the frequency of inbound and outbound movements rises sharply, this traditional management model exerts a severe negative impact on overall operational efficiency.
(4) **Lack of Real-time Data:** Traditional management methods prevent grain warehouses from updating inbound/outbound and inventory audit data in real-time, thereby hindering the effective sharing of information resources within the organization.
In response to these complex management challenges within the grain storage sector, SCO has developed a solution—tailored to specific operational realities and requirements—that leverages Radio-Frequency Identification (RFID) technology. This solution is designed to streamline inbound/outbound processing, facilitate accurate inventory auditing, and enable rapid stock retrieval, thereby achieving highly efficient and precise management of grain storage operations.
III. The RFID-Based High-Efficiency Management Solution
1. Inbound Management
The Inbound Management module is primarily responsible for the automated registration of various flour products as they enter the warehouse through designated receiving channels, as well as for facilitating other auxiliary management tasks related to the receiving process. Recommended Solution for Automated Inbound Registration: RFID Vertical Warehouse Portal
(1) Product Introduction
Supports multi-tag reading and utilizes an infrared-triggered reading mode. It features integrated sound and light alarms and supports headcount statistics for personnel entering and exiting the area. The device supports Ethernet communication and can be expanded to accommodate various other communication methods, such as Wi-Fi and 4G.
(2) Product Features
1. Exceptional multi-tag reading capability, with extremely low rates of missed reads and misreads.
2. Specially designed antennas ensure precise coverage of the portal area with no blind spots.
3. Built-in alarm light and buzzer.

5. Equipped with a 21.5-inch capacitive touchscreen that displays real-time inbound/outbound information and quantities, while also tracking the number of people entering and exiting the area.
(3) Operational Workflow
When flour—to which electronic tags have been affixed—is ready to enter the warehouse via the inbound conveyor system, it passes through the RFID warehouse portal installed at the conveyor’s exit point. At this moment, the RFID portal automatically performs an RFID scan to identify the flour. Once identification is complete, the flour’s information (such as flour type) is displayed on the portal’s touchscreen interface, accompanied by an audible alert. Simultaneously, the portal transmits this inbound data to the backend database for updating. At this point, the automated registration of the flour’s entry into the warehouse is complete.
Additionally, handheld RFID readers deployed on-site can be utilized to facilitate other auxiliary management tasks related to inbound operations—for instance, querying the historical inbound records for a specific type of flour, or automatically generating and printing inbound record reports for a specified date.
2. Outbound Management
Outbound management primarily involves accurately and automatically registering the departure of various types of flour required by customers—based on the specific details of their pickup orders—as well as handling other auxiliary management tasks.

(3) Operational Workflow
Warehouse personnel first utilize an RFID handheld reader to process outbound shipment tasks. During processing, staff members simply select the specific outbound task requiring attention on their handheld devices (once the Sales Department has processed a customer’s request, an electronic sales order is generated and automatically transmitted to the backend server; the Warehouse Department receives this order in real-time, and upon completion of the initial processing, a corresponding outbound task is created and automatically sent back to the backend server, where it becomes available for query and download by handheld devices on the warehouse floor). Upon confirmation, the handheld device—acting through the backend server—automatically downloads the details of this specific outbound task to the fixed-position RFID reader/writer located at the warehouse exit. Once the download is complete, the fixed reader/writer displays the required outbound quantities for each type of flour associated with the current task, alongside the quantities already dispatched, on an attached LED display panel.
Warehouse staff then consult the LED display to determine the required outbound quantities for each flour type; accordingly, they transfer the requisite flour sacks from the RFID-enabled shelving units onto a forklift. On-site personnel then maneuver the loaded forklift into the RFID portal gateway. As the flour enters the gateway, the unit automatically lowers its rolling shutter door and initiates an RFID scan to identify the flour cargo. Upon completion of the identification process, the flour’s details (such as its specific type) are displayed on the gateway’s touchscreen interface, accompanied by an audible alert. This entire inventory-counting process takes a mere 1 to 3 seconds to accurately verify a batch of goods ranging from 1 to 1,000 items. Furthermore, the gateway automatically transmits this outbound transaction data to the backend database for real-time updating. At this juncture, the accurate and automated registration of the flour’s outbound movement is successfully completed.
Additionally, the on-site RFID handheld devices can be utilized to facilitate various auxiliary management functions related to outbound operations—such as querying the historical outbound records for a specific type of flour, or automatically generating and printing outbound transaction reports for a designated date range.
