Alarge department store has been attaching tags with barcodes to merchandise, and employees use barcode readers to scan merchandise at the cash register. however, the wireless barcode readers need new batteries 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 using RFIDs (Radio Frequency Identification) for tracking inventory. Unlike the wireless barcodes, RFID uses radio waves to communicate with readers. One very common advantage of an RFID is the scanning range. Wireless barcodes, for instance, requires the reader to be close to the barcode before it can see it to scan it. However, RFID systems can scan a tag as long as it is within range. This is important because it reduces wastage of time on labor-intensive processes and increases task speed, convenience, and project turnover.

Many passive RFIDs use tags that are powered by electromagnetic energy. Such energy does not consume power.
