by now most of us are used to the idea of doing stuff without actually having
to touch anything and while this sadly doesn't work in all public bathrooms
it's become commonplace to do all sorts of stuff like unlocking hotel rooms
traveling on subways entering our cars and buying overpriced merch at theme
parks just by tapping something or being
near it but this is not Harry Potter style magic folks it is all thanks to a
technology called RFID little chips that somehow make
everything smart at least according to someone's marketing department somewhere
but how does RFID even work I mean it's just a tiny chip thing embedded inside a
card right where's the battery well most
RFID chips called Tags not that kind of tags actually
don't need a battery mind blown right because they draw power from whatever
happens to be reading them run-of-the-mill RFID tags and credit
cards and wristbands are classified as passive and only consist of a tiny
antenna an embedded CPU to process radio
waves and a small amount of data storage
they're small and low power enough to just grab energy from a powered chip
reader making them convenient enough to use just about anywhere wait a second
lonus anywhere are we going to start seeing terabyte sized RFID tags that can
replace my trusty mechanical hard drive
well no to keep power consumption low enough that they can be powered by radio
waves and to keep costs down so we can
put them everywhere RFID tags hold only a few kilobytes of data which is fine
because in today's connected world you don't need more than a few kilobytes of
storage for the RFID chip to be an incredibly useful tool no but really
though along with the useful things that can be done with a few kilobytes uh
paperless ticketing for events and Apple pay which you NFC a two-way short range
form of RFID come to mind thanks to many
RFID readers like your cell phone for example having their own network
connections RFID chips are often simply used as pointers to more information or
more complex functionality somewhere else cool right entertainment venues
offer RFID kiosks to Auto checkin on
Facebook or Auto tweet that you're too lazy to take your phone out of your
pocket cars have RFID tags that can help you recover them if someone decides to
jack your ride casinos have RFID chips in their chips to help people from
pulling in Oceans 11 and you can even have a tag attached to your dog to find
him if he decides to run away because you spent all night playing Counter-Strike and forgot to feed the
poor soul and because RFID is such a
customizable technology many uses for it
have most likely not even been fully realized yet I mean imagine RFID tags
replacing barcodes on everything you purchase so you can just walk out of the
store with all your new stuff and an RFID scanner will read your tagged end
credit card to automatically bill you no checkout lines required mind blown again
right I mean there's even a number of projects around smart dust RFID
transmitters about a cubic millimeter in size that could do everything from
Analyze traffic patterns after being mixed into asphalt to keeping tabs on
your stuff whenever it's taken out of your home so you know it's been stolen
to flowing through your bloodstream to monitor the state of your health I mean
whoa hold on a second there lonus let's just back this up what if I don't want
to eat RFID pixie dust or have every single thing I buy track that sounds
like some kind of 1984 Nightmare and
yeah I hear that guys we actually have some tough questions to answer as a
society about how much privacy we want to trade for Automation and convenience
which is the downside of RFID technology
