"While barcodes need to be manually scanned, RFID simply broadcasts its presence and data to electronic readers."
No mention of the fact that the RFID tag has no internal power of its own and will only broadcast if scanned within range
"But with remotely readable tags on everything from boots to beans"
Personally I would not call a reading range of a few cm's remotely readable.
AFAIK The only real advantage that RFID tags have over barcodes is that you do not need line of sight.
