The RFID tag readers either Mobile RFID Readers or they can be Fixed-Mounted RFID Readers that activate the tag using the appropriate radio frequency, and the tag transmits its encoded identifying data back to the reader. Importantly, unlike barcodes, certain types of RFID technologies do not require line of sight for tag reading. With this critical functionality, organizations can dramatically transform how they manage the flow of goods and the tracking of assets throughout their organizations, supply chains, and distribution.
The most common RFID solutions and systems use UHF RFID passive tags. The tags include a small antenna and chip with limited functionality, so that they can be produced inexpensively enough to be part of the packaging. These tags are powered by the radio signal sent from the tag reader. As a result, they do not require local battery power, which saves on cost and complexity.
When the RFID tag receives the electrical power signal from the UHF RFID Reader, the tag energies “wakes up” and transmits the data encoded in the tag, which typically includes a unique reference code number that references the product description (essentially the barcode SKU) as well as a unique identifier, which is a serial number. This data file is received by the RFID tag reader and then forwarded to the enterprise software systems in the "cloud".
Used and set up correctly, typically this RFID technology is so powerful as it provides HUGE benefits and advantage delivering greater profits and efficiencies as it easily provides greater visibility of knowing exactly in real time, where ALL your valuable assets are located providing full visibility and therefore preventing losses and brining better accuracy.
