What is RFID and what are it's possible uses?

Answer 1

Basically its a little radio transmitter and computer chip with no battery. You hit it with a radio signal at the right frequency and that generates enough power for it to answer back with a identifying number.

Possible uses? Limitless.

Let's say you buy gas at Chevron all the time and they implement an RFID system. You pull up at the pump put the hose in your car, fill it up and leave. No credit cards, no pin numbers, no waiting for authorization, no reciepts. It knew who you were and who to bill because you had a RFID chip on your car.

Let's say you run a clothing store and want to know when it's time to order more leather jackets. Well, since you know exactly how many you have on the floor (you scanned them when you unpacked them) and you know exactly how many you've sold (you scanned them as you sold them) you know when you're running out.

When the technology is perfected, imagine going to the grocery store, filling up a shopping cart, then hitting the checkout stand. No need to scan your items. No need to weigh anything. No need to DO anything. You roll your shopping cart up to the clerk, and he says "That'll be $64.23. Would you like help out to your car?" How's that for a short line?

Now about the "evil" uses. You bought that leather jacket with the RFID chip in it. Now you go back to the clothing store and the computer recognizes one of its jackets coming back. The salesman now knows everything you bought at that store for the last two years or so. He glances at the list and notes that you haven't bought slacks in a while.
"Good afternoon, Mr. Marcus. Welcome back." This disturbs some people.

Let's talk worst cases. Let's say driver's licenses have RFID chips built into them. Now you can be identified immediately wherever you go if they have an RFID scanner. Stores know what you bought and when. Even if you pay cash, the divorce laywers know all about those roses you bought. A necklace turned up missing from a jeweler on Sunday and another one on Tuesday. You were the only one there both days. It may be a coincidence (two different shoplifters?) but you're now the prime suspect.

Hope this helps some.

Answer 2

If an RFID tag is an similar aspect as a microchip, then each from time to time you could. notwithstanding, purely because you won't be able to experience it would not propose there is no longer one. If the dogs has a good volume of sub-Q fat or thick skin you is purely no longer waiting to experience it. the possibilities of being waiting to experience a chip on a wide dogs is likewise incredibly low (both genuinely one of my great dogs are lean and that i'll't experience the chip on both genuinely one of them). Microchips are commonly inserted purely below the floor proper between the shoulder blades. notwithstanding, they could "migrate" to different elements...incredibly in the experience that they have been in position for a lengthy time period. And purely because between the shoulder blades is the classic region, that would not propose that someone won't be able to insert it some position else. it really is the reason even as a vet scans a dogs for a chip they commence alongside the back yet then run the scanner over the dogs's shoulders and abdomen besides.

It stands for “radio frequency identification,” and essentially means that radio-activated computer chips are used to track products in a supply chain.
I work for a library system, and we use it to allow patrons to check out books themselves. We have stations where they scan the books - like you would a bar code, except it's not with an optical laser.
