Radiofrequency Identification (RFID) vs. Barcode /Nursing Informatics Reading and Sharing

A primary difference between radiofrequency identification (RFID) and barcode is that RFID has great read range. While the read range for barcode ranges from inches to a few feet, passive ultra-high frequency (UHF) RFID ranges up to 40 feet if readers are fixed or up to 20 feet if readers are handheld. Active RFID has a read range hundreds of feet. Active RFID tags are battery powered and emit a signal while passive RFID tags require activation by a reader.
