If you don’t know what an RFID tag is, you will soon. An RFID tag is a non-contact electronic device that transmits a signal to a reader that passes close to it. What’s the big deal you ask? Well, some RFID tags do not require a battery, last for years, and are the size of a grain of rice. The fact that they can be hidden seamlessly in anything, can hold a password or other information, don’t need any maintenance and are just generally pretty cool means that these devices are creeping into just about everything. So what are the most useful places for an RFID tag? How about the most terrifying? Let’s investigate.
Most Penny Pinching:
Some theme parks are adding drink stations throughout the parks. Historically they had two options, have an employee at each station to ensure people aren’t stealing beverages, or trust people not to fill up old 2 liter bottles with free Cola. That didn’t work out too well for the theme parks, so now we have…..RFIDcups! Your cup is time stamped, and you can get drinks for a set amount of time after purchasing that cup. After the time stamp expires, the beverage fountain will not dispense to you. At least until someone with a lot of time and know how makes their own time stamped RFID cups, but until then…

Grab a drink! And Enjoy it during the next 59 minutes…
Most Green:
Saguaro cacti have long been stolen from national parks out west, and sold for top dollar through a sort of Cacti black market, or green market if you will. Not surprising, considering this cactus takes 75 years before it even starts to look like a cactus. Not the sort of thing you buy as a small plant and watch grow. So the national parks service has installed RFID tags in many cacti in national parks, so if a person has a suspected stolen cactus, authorities can scan it and see if, and from where it was stolen.

Put your hands up, cactus thief!
Most detrimental to the odds of your pet having a grand adventure:
Many pets now have an RFID tag put in them when they are young, often while being spayed or neutered. These tags allow a vet or shelter to scan the pet if ever lost and recovered. The chips put in these pets can have just a simple phone number, or a web URL leading to a page with full contact information on the owners and even pet allergies and medical conditions to be aware of.

No, this is not how they give the kitties their RFID tags.
Most Unsettling:
Party-goers at some pool based hotspots can choose to have an RFID tag put under their skin, with their age and debit card number on it, so they don’t need to carry a purse or wallet. I can think of no appropriate picture of that.. so lets just look at the cat above again.
