hey what is up guys I'm Kay PhD here and this is NFC explained so what is NFC well NFC first of all stands for near field communication and it's a technology that allows you to transfer small amounts of data between two NFC enabled devices which we'll get to in a second and to be honest you actually don't have to touch the devices together it's near-field which means you can get usually within about a centimeter of the devices and they will successfully transfer the data and there are a lot of really practical applications for it there are also a lot of NFC enabled devices already out there you might be watching this on one right now and I'll have the link to those down below the like button on this video if you have an NFC enabled phone it'll be built into the back usually into the battery cover or into the battery itself so the back of the phone is where you'll find the NFC chip in your NFC enabled devices this is an NFC tag and inside of it is a small thin microchip that can hold a certain amount of bytes of information which varies per chip but every NFC command that you write to one of these takes a small number of bytes maybe three to five bytes per command so you can hold multiple commands per card so each one of these can hold a couple of commands and you can even have it tell one device to do one thing but when another device touches it it'll tell that device to new another thing so you can have strings of commands on here it's a really versatile device for just a small little microchip inside of a little plastic shell so you can use an application like NFC task launcher on Android or NFC interactor on Windows Phone and I'm sure when the iPhone finally has NFC there will be an app for that too but these apps will let you read and write commands from and to the NFC tag and so let's go and do this one for example let's go ahead and make this the tag that I tap every time I leave the house to walk to class so I'm going to program this red tag here and the link to the Android app I'm using is down below basically what I'm going to do is create a new task make it an NFC task and then add the actions that I want to be associated with that task and this is the whole list of all the things I can do to make this phone change or what I wanted to do when it taps the NFC tag so you can see it's a pretty awesome list so when I leave the house I want to track the sound all the way up I also want to maximize a screen brightness and I also want to disable Wi-Fi since I'll be hopping on to a 4G network so but this is basically a huge list of all the things you can see there's screw integration a whole bunch of different system settings but I'll go ahead and crank Wi-Fi off hit next and then I'll make sure all the toggles are set to what I want it to do so when I tap it I want it to disable Wi-Fi I want it to enable the vibrate mode for sound and crank the screen brightness to 100% when I walk outside once you've picked everything this is what the tag is going to do go ahead and save and write and swipe the tag on to the back of the phone and as you can see it was written successfully and we're done so there you go now whenever I leave the house with this guy in my back pocket I can literally touch my phone to my butt and it'll do all these commands that I already programmed it to do and that's it you're set I'm set to go so clearly NFC is awesome so without any further ado throw an actually with a quick top five I know you didn't think this is a top five video but let's go ahead and take a look the top five awesome things that NFC can do number five app launching let's say I stick one of these in my car dock I can have it launched Google Maps when I put my phone in it that's simple brilliant number four at the bedside and actually use this one whenever I tap my phone to the NFC sticker next to my bedside it dims the screen silences the phone and sets an alarm for the next morning that I have already predetermined number three is business cards now clearly paper business cards the traditional type aren't really going anywhere anytime soon and we've seen people attempt to put QR codes on the back I don't really like those but an NFC enabled business card that takes the Swiper right to your online resume or your website would be pretty sick number two boarding passes and transit tickets obviously there are a whole bunch of different things that are awful about the system at least in the United States for boarding passes and transit tickets in getting paper and getting on to the transit that you need to get on so having just the ability to swipe your phone and board the plane or swipe your phone and get on the train without having to worry about that is definitely something we'd be looking forward to number one mobile wallet having your phone be your wallet in your pocket without having to carry a whole bunch of cash or coins is awesome now swiping your phone to pay at a McDonald's or a Dunkin Donuts can either make you look like a complete idiot or a complete boss depending on whether it works or not but when it does work like it did for me at a 7-eleven a couple of weeks ago you see that little Google Wallet logo you swipe to pay and you start walking out the store you automatically blow the mind of anyone who is in that store at that moment sometimes they don't actually realize that you just paid and they start to stop you like hey why are you walking out the store right now and you look back and it's processed the payment is done it came from your Google Wallet account and speaking of Google Wallet Google Wallet is basically on the forefront of pushing this technology basically the mobile wallet stuff to be in the forefront and that's why Google is doing work right now so those are your top five honorable mentions go to parking meters those would be cool NFC enabled parking meters so you could just pay with your phone because no one likes carrying coins around they're incredibly cumbersome and just terrible and other honorable mention goes to Android Beam because that's pretty much the easiest and most efficient way to share files at least small ones between devices so if I want to share my file with you I don't have to upload it somewhere for you to download it somewhere or email it to you or text it to you that all just is an extra step I don't want to have to take here let me just give you the file tap the backs of your phones together and Android Beam takes right care of that ever since Android 4.1 I believe that's a new feature so every Android phone with Android 4.1 or above has Android Beam enabled so if it has NFC just tap the back and send a picture or video whatever and another honorable mention goes to car keys because how awesome would it be to just walk up to your car found it and the door unlocks that'd be sweet obviously it wouldn't be the most convenient thing in the world because say you're in a rush and you just miss that exact right spot but who cares it's awesome so clearly I love NFC I think it's a pretty underrated technology and I've recently started using it more because I've found all the awesome things that it can do really enticing so I'm getting more back into it I have a lot of NFC tags and I definitely want to get more ideas from them so definitely let me know what are you guys using NFC for personally I'm really just starting off with like you know leaving a house with an NFC tag or having it by the bedside but let me know what you guys use and I'm sure you're watching this on an NFC enabled device so go out and try to pay for something crazy with your phone see what happens or don't either way thanks for watching and I will talk to you guys in the next video you
