Barcode vs. RFID tag
In order to optimally manage the supply chain and production process, it is necessary to track the movement of each unit of goods, sometimes every detail. Modern technologies make this task easier.
Today, there are many methods of auto-identification, based on the principle of contactless reading of information.
The most popular and common of them is bar coding. However, it is rapidly catching up with radio frequency identification (RFID). This technology is successfully used by the world's largest retail chains, such as Wal-Mart, Target and Tesco.
RFID is a generic term for technologies that are used to automatically identify radio wave objects. They are emitted by special marks placed on identifiable items. RFID allows you to track the location of items, boxes and pallets as they move through the supply chain to the consumer. Readers (RFID readers) collect information about each object into a central database.
There, code tags are identified with information about identifiable items, as a result of which the user of the system can at any time receive an exhaustive report on the relevant subject.
RFID technology provides higher speed and accuracy of information transfer in the supply chain than bar coding.
This difference is particularly noticeable in organizations with global supply chains and an extensive distribution and retail network.
More extensive RFID information collection capabilities ensure that there are no discrepancies in the data and greater transparency in the logistics scheme. This contributes to cost reduction and more efficient operation.
The goal of any retail store is to maximize customer satisfaction by maintaining optimal inventory levels while reducing operating costs. The key points of trading are receiving goods, reconciling and setting prices, moving goods to the sales area from the back room.
Successful trading can be hampered by the following problems:
• the goods have not entered the store
• the product entered the store, but did not hit the storefront on time
• the goods are already on display, but it is not clear whether it can be sold
To avoid this, many retailers invest in technology solutions such as enterprise resource planning (ERP) or warehouse management systems (IMS).
But they are based on processing a large amount of data, so reliable sources of information are needed for normal operation. These sources are barcodes and
