RFID Warehouse Logistics
Introduction
At present, with more and more fierce market competion, it is significant for enterprise to improve produce efficiency and
reduce operating costs. Warehouse logistics is widely used in every industry. Designing and buliding a set of warehouse
management process, improving the rate of turnover in warehouse, reducing occupation of operating funds, transforming
frozen funds into cash, and lower cost of products that warehouse eliminated, all of those are key parts to improve produce
efficiency.
Warehouse management system usually operates by barcode tag or manual warehouse management invoice, those have
obvious shortcomings:
 Managing by barcode: easy to be copied, polluted, damped and only can be read within a close distance
 Recording by manual: complex, easy to get error with large numbers, increasing labors cost
 Large workload in inventory by manual, long inventory cycle, it cannot be found in time that goods are in shortage
or stolen
With RFID, enterprise warehouse management will get open and more efficient. The approximate process is as the following:
put tag into barcode, stick it on the package or pallet of every product, write product information such as position, etc. in tag,
write destination information when product is in or out of the warehouse, set fixed or handhold reader in warehouse and
every dealer channel to recognize and monitor products circulation.

System design
When products are entering the warehouse:
♫ In the packaging products workshop, workers stick RFID tags on products, pack in batches and stick box marks. The
products that need pallet can be stick pallet tag；Methods of sticking tag：
 stick product unit tag
 stick on the outer package, when several products packed
together
 pallet tag, connecting with the data unit tag or outer package tag
♫ Packed products enter in the warehouse through the channel set RFID
reader and antennas by handling tools. RFID get the number of products
entering and record in system automatically. Take products with pallet tag as
an example, the information of every pallet products s written in pallet tag by the reader at the entrance, meanwhile, data
connection of orders is formed and the warehouse management system will assign the position, or manager has assigned the

position for these products at the beginning. Then the network system will send storage order to the warehouse client (or
forklift car system). At last, according to the order, forklift driver will store the products to appropriate position.
♫ After finishing storage, system update the stock data, and mark the position information of every batch of products.
When products are exiting the warehouse:
♫ The sender in logistics department produce the stock-out list on the basis of the delivery products list. That means
according to stock-out priority (for example: the item with earlier production date should be sent out in advance), they
check out the position and the stock status of the required goods. If client points out the production code, they can check
with the code and get the information of the goods position, pallet, required goods and related vehicle.
♫ Goods-picker send the stock-out list to warehouse manager. Warehouse manager check the information and arrange
forklift driver to carry out the required goods.
♫ When the forklift is passing the exit, the RFID reader there will read the pallet tags to stock-out information, and check
whether the products are matched with the production code and position in the stock-out list or not.
♫ After the products are stocked out, warehouse terminal provides the stock-out information for manager to confirm, and
automatically update it to database.
When workers are doing inventory
♫ Workers can inventory by handhold reader regularly, read products tag information closely, and compare it with that
exists in management system, to check whether the inventory information by manual is the same with that in management
system or not. If it is not, they can correct it on the site. This method can shorten 85% time for enterprise to make an
inventory, greatly improve work efficiency and also increase the inventory cycle times.
System Performance
 Reduce labors cost by 20-30%；
 Lower the rish of products lost, as the result of that 99% products are visible
 Reduce working time by 20-25%
