o Automatic data collection: The RFID system can automatically collect cargo information, such as data on arrival inspection, warehousing, warehousing, allocation, transfer and inventory counting. This helps to improve the speed and accuracy of data entry.
o Location management: Through RFID technology, we can manage each location accurately. The label records the location of the location, the type of storage and other information, which helps us to achieve scientific and effective warehouse location management.
o Real-time monitoring of inventory: RFID technology allows us to know the current inventory of products in real time. This helps to plan production or procurement, as well as improve inventory turnover, reducing inventory overstock and waste.
• Difference between RFID and traditional barcode systems
o Non-contact: RFID tags do not require direct line of sight and can read information without opening the package.
o Reuse: RFID tags can be reused, reducing costs.
o Fast scanning and big data capacity: RFID readers can quickly scan multiple tags and store large amounts of data.
3. How RFID Inventory Management Works
Attach RFID tags to Items:
o Attach RFID tags: First, attach RFID tags to items. These labels can be pasted, sewn, fastened, or embedded.
o Unique Identification Code: Each RFID tag contains a unique identification code, similar to the “ID card” of the item. This identification code can be a number, a letter, or a QR code.
Data Capture and Transmission:
o RFID reader: When an item passes through a channel equipped with an RFID reader, the reader sends a radio signal that activates the chip on the RFID tag.
o Read information: The chip reads the information stored on the tag, such as the type of item, date of manufacture, batch number, etc. This data can be in text, number, or other formats.
Data Processing and Inventory Updates:
o Inventory management software: The data from the RFID system is transmitted to the inventory management software. These software can track the location, status, and quantity of items.
o Inventory record updates: When items move in and out of the warehouse, are sold, or moved, inventory management software updates inventory records accordingly. This helps to understand changes in inventory in real-time.
