(RFID) Smart Inventory Since 2007, many companies have adopted RFID technology Barcode technology no longer meets the needs and requirements of companies of all sizes, prompting technology and information companies to seek a suitable alternative. The alternative is Radio Frequency Identification (RFID). For many years, barcode technology has been raised on the top of inventory management techniques and sales and purchasing processes in companies of all types and sizes.  One key flaw, however, was its inability to control inventory and inventory work. This gap is evident when we find that many companies are using, in addition to barcode technology, systems of protection and warning to adjust their inventory, and we find all companies to inventory their inventory manually, which takes extra time and money.
