RFID Tunnel Conveyor Solution

The RFID Tunnel (or RFID Conveyor) is a fixed RFID system integrated into conveyor lines in warehouses, manufacturing plants, and retail distribution centers. The system consists of RFID readers and antennas enclosed within a shielded tunnel structure, enabling the automated counting and identification of items passing through with high precision and reliability.

Order Management (PO)

The system accurately scans and records key information such as PO codes, EPCs, and other identifiers, then automatically stores and synchronizes the data with ERP, SAP, or WMS systems.

Error Detection & Alerts

The RFID Tunnel is equipped with an intelligent error detection and alert mechanism. When an anomaly is detected, the system triggers a red signal light and audible alarm to notify operators.

Automated Item Counting

The RFID Tunnel automatically identifies, verifies, and counts items as they move through the conveyor—without requiring box opening. The RFID technology achieves reading speeds of up to 1,200 tags per second with an accuracy rate of 99.9%.

GS1 Decoding Standard

The RFID Conveyor system supports reading and decoding of RFID tags compliant with international GS1 standards. The device operates across dual frequency bands, including 865–868 MHz (EU standard) and 902–928 MHz (US standard).

RFID Tunnel System

  • Conveyor Belt: Transports cartons or items through the RFID reading zone.

  • Reading Chamber:

    • 4–6 UHF RFID antennas

    • 1 high-performance RFID reader

    • Object detection sensors for item entry and exit.

  • Software: Captures and displays RFID read data in real time.

  • Signal Light & Buzzer: Indicate reading status (Pass/Fail).

  • RFID Printer: Prints and encodes RFID labels before application to goods.

  • RFID Tags/Labels: Attached to items or cartons for identification.

RFID Tunnel Operating Process

  1. Preparation
    RFID tags are attached to cartons or individual items. Each tag contains key data such as order number, product code, size, and color.

  2. Loading Cartons onto the Conveyor
    Operators select the scan command, PO, or order to process, then place cartons on the RFID conveyor according to the following rules:

    • Only one carton per scan.

    • Maintain 30–50 cm spacing between cartons.

    • Do not stack cartons.

    • Avoid metal objects or liquids near the RFID antennas.

    • Ensure consistent tag placement on all cartons.

  3. Automatic RFID Scanning

    • The conveyor moves cartons through the RFID reading zone.

    • Antennas emit signals and capture RFID tag data.

    • The RFID reader transmits collected data to the management software.

  4. Monitoring on Software Interface

    • PASS (OK): The number of tags read matches the expected count; the signal light turns green.

    • NG (Error): The system detects missing, duplicate, or unreadable EPC codes; the signal light turns red and the alarm activates.

  5. Error Handling

    • Operators remove the NG carton from the conveyor.

    • In software, select Re-scan to identify faulty or missing tags.

    • Repair or replace defective RFID labels.

    • Re-scan the carton.

  6. Data Recording and Synchronization
    Once scanning is successful, all data is saved to the central database and automatically synchronized with ERP/SAP/WMS systems.

  7. Process Completion
    Operators export the summary report, shut down the system, clean the conveyor, and inspect antennas and sensors for maintenance.
