Application of RFID in warehousing

RFID (Radio Frequency Identification) technology, also known as radio frequency identification, or electronic tag, is a communication technology that can identify specific targets through radio signals and read and write related data without establishing a mechanical or optical connection between the identification system and the specific target. touch.

In traditional warehousing management, it is often seen that items are distinguished and verified manually, and the goods entering and exiting the warehouse must have documents as evidence, which is inefficient and prone to errors. In warehouses that apply RFID technology, this problem can be solved relatively easily.

The core of RFID is to make each product have its own specific piece of information to distinguish it from other products. In conjunction with this, RFID Readers are set up at the entrance and exit of the warehouse to read the information of the goods passing through the readers. Information, you can use the RFID handheld client to scan items in the warehouse. In this way, it is easy to collect and organize information on the identification, positioning, tracking, transportation, storage and withdrawal of goods from the process of goods entering the warehouse to the goods leaving the warehouse.

Compared with the traditional barcode/QR code warehouse entry and exit management system, RFID overcomes the following problems:

a. The code reader cannot scan the barcode normally when the light conditions are too poor;

b. Only one barcode/QR code can be scanned at a time, which is less efficient;

c. Barcode/QR code labels are easily damaged or peeled off. If this happens, the scanner will not be able to identify the target;

d. The barcode/QR code scanner must be at a close distance and not blocked by objects before it can read the barcode;

What are the differences between RFID, barcodes and QR codes? Let’s compare them through a table:

01 Goods and labels

Attach RFID tags to the goods, or place the goods on RFID-equipped boxes to complete the binding of the goods to the tags.

02 Goods put into storage

After receiving the cargo information and vehicle information, it is transmitted to the warehouse. The warehouse's warehousing management system will allocate the storage area and storage location of the goods according to the actual situation. When the goods arrive, warehouse staff can use the RFID reader to verify the goods. The reader will quickly read the relevant information of the goods, quickly check whether the goods are correct, and ensure that the goods are put into the warehouse in a timely manner. After the goods are delivered to the designated warehouse area, the reader will scan and check again when entering the warehouse, and the information will be transmitted to the warehouse management system. When errors occur, they will be corrected manually.

Compared with traditional warehouse management business processes, RFID smart warehousing has the following advantages:

a. The storage space in the warehouse area is no longer arranged by the dispatcher, but is allocated by the system;

b. There are readers and writers for scanning during storage and shelving, which improves the accuracy.

03 Goods leaving the warehouse

When leaving the warehouse, the system will automatically call up relevant information about the goods, which can determine the warehouse area and cargo location of the goods. Then use a forklift to remove the goods and check whether the goods are accurate through RFID reading. When accurate, the green light will turn on. When scanning, the cargo information will be entered into the computer, the warehouse management system pickup information will be confirmed, and the cargo information in the system will be automatically changed.

Compared with the traditional warehouse management outbound business process, the use of RFID technology has the following advantages:

a. The system will automatically generate a pick-up order, eliminating the need for manual handwriting of the pick-up order, reducing the error rate;

b. Sorting is carried out by automatic sorting machines with RFID readers, which improves efficiency and reduces error rates;

c. The RFID reader is used to check the goods shipped out of the warehouse, which improves the efficiency of inspection and enables automatic updating of goods inventory information.

04 Abnormal goods leaving the warehouse

When there is an error, the system will remind you, the red light will light up, and traffic will be prohibited.

05 Abnormal goods are shipped out of the warehouse again

Managers need to return to eliminate the abnormality and go through the warehouse again. They cannot leave until the inspection is correct.

Since traditional inventory work is completed manually, it not only wastes a lot of human resources, but also is prone to errors and inefficient due to cumbersome operations. However, after adopting RFID technology, these problems can be solved well, so that the inventory work can be completed quickly and with high accuracy.

By reading the information of the goods through the reader and comparing it with the goods in the system, you can easily find out the quantity, type, warranty period and other information of the goods.

Compared with traditional inventory work, the use of RFID technology has the following advantages:

a. Save a lot of human resources and reduce labor costs.

b. Improved work efficiency and accuracy, and reduced corporate losses.

c. Adjust the cargo location through the management system without manual adjustment, which is more intelligent and accurate.
