Zara introduced the use of RFID technology in its stores in 2014. The RFID chips are located in the security tags which are removed from clothing when it is purchased and can be reused. The chip allows the company to quickly take an inventory by detecting radio signals from the RFID tags. When an item is sold, the stockroom is immediately notified so that the item can be replaced. An item that is not on the shelf can easily be found with the RFID tag.
