This appears directly before the quote David pasted ...
So we have a "99.99% magnetic" device that has a range of 10 to 50 feet.
And it's an "active transceiver" ... that is, an active 99.99% magnetic
transceiver ... oh, and the protocol works with many thousands of tags,
but later in the article, it's cited as having read rates of 10 to 20
tags per second.
Or we have a journalist who was overtaken on the first lap and is still
panting to catch up...
I don't doubt that the protocol is being designed for a purpose, but who
can tell if this is the standard of journalism?
