According to Sanford Bernstein, a retail analyst at the company, Wal-Mart can save $8.35 billion a year by using RFID, mostly because labor costs are saved without the need to manually view the incoming barcode. While some other analysts say the $8 billion figure is too optimistic, but there is no doubt that RFID helps solve two of the biggest problems in retailing: goods that break goods and losses (products that have been lost because of theft and supply chain disruption), and Wal-Mart loses almost $2 billion a year. If a legitimate company's turnover reaches that number, it will 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%.
