A large department store has been attaching tags with barcodes to merchandlse, and employees use barcode readers to scan merchandise at the cash register. However, the wireless barcode readers need new batterles much too often, and using this system for Inventory tracking is very time-consuming. In one to two sentences, describe the emerging technology the department store should consider using for tracking Inventory.

The department store should consider implementing RFID (Radio Frequency Identification) technology for tracking inventory, as it allows for quicker scanning without the need for line-of-sight and can read multiple tags simultaneously. This system would not only enhance efficiency during checkout but also streamline inventory management, reducing the time employees spend on stocktaking. One potential solution to battery management can be utilizing passive RFID tags, which don't require batteries to function but instead harness energy from the reader. This makes the system more sustainable and minimizes the hassle of frequent battery replacements.
