The principle and reason of smart label
1. The basic working principle of RFID technology The basic principle of RFID technology is not complicated: After the label enters the magnetic field, receives the radio frequency signal which the reader sends out, by the induced current the energy obtains the product information (passive tag, passive label or passive label), or sends the signal of a certain frequency actively (active
tag, active label or proactive label); the reader reads the information and decodes it and sends it to the central information system for data processing.
A reason to be admired
2. Retailer's admiration for RFID According to Sanford, a retail analyst at Bernstein, Wal-Mart can save $8.35 billion a year by adopting RFID, mostly because of labor costs saved by not having to manually view the barcode. While some other analysts think the 8 billion-dollar figure is too optimistic, but there is no doubt that RFID helps solve two of the biggest problems in retailing: goods that are broken and lost (products that have been damaged by theft and supply chains), and that Wal-Mart loses almost 2 billion dollars a year in a single heist. If a legitimate business can reach that figure, it could be ranked No. 694 in the rankings of the 1000 largest companies in the United States.
The research agency estimates that this RFID technology can help to reduce theft and inventory levels by 25%.
