NFC, or near-field communications, is a hardware feature that has been built into most Android phones for the last four years. It's essentially a low-power data connection that can be used to initiate a quick command by bringing your device within range of a compatible receiver, be it tap-and-pay with Google Walleta file transfer via Android Beamor a Tasker profile triggered by a specific NFC tag.
That last example has quite a few practical implementations. NFC tags can be purchased for less than a dollar each, and when combined with an automation app, can trigger a series of events on your phone and even in the real world. All of this occurs by simply placing your phone within range of the NFC-embedded sticker. With that in mind, the folks over at Rice Or Noodles came up with a rather innovative way to put your phone's NFC reader to good use. After a bit of one-time setup, you'll be able to power on your Windows PC by simply laying your phone down on your desk—I'll outline the process in more detail below.
Open your Control Panelthen click "View network status and tasks" to begin. After that, head to the Advanced tab, then make sure the "Wake on magic packet" option is enabled. With your computer now set up properly, you'll need to jot down a few numbers in preparation for the setup on your Android device. On your keyboard, hold down the Windows button, then press "R" to open the Run dialog. From here, type "cmd" and click "OK. Next, scroll through the list and find the "Ethernet Adapter" section.
If you'd rather try before you buy, you can use the 7-day trial version from this linkbut make sure that "Unknown Sources" is enabled in your phone's settings under "Security" before you launch the installer file.
After that, install Triggerwhich will be used to read your NFC tag. First, you'll need to configure the app that will actually be waking your PC. Open WoL, then tap "Add New. After that, tick the box next to "Send as Broadcast," then enter your Subnet Mask information.
When you're done, tap "Save. Next, open Tasker and tap the three-dot menu button, then select "Preferences.
Name this task "Wake" and then press the checkmark icon. When you're done with that, go ahead and back all the way out of Tasker.When you pair the headset with a device for the first time after you bought it, or after you initialized the headset the headset has no pairing informationpress and hold the button for about 2 seconds when the headset is turned off.NFC Tools : How to read NFC cards on your computer
The headset enters pairing mode automatically. When you pair a 2nd or subsequent device the headset has pairing information for other devicespress and hold the button for about 7 seconds. Make sure that the indicator flashes blue and red alternately after you release the button.
The computer is placed within 1 m 3 feet of the headset. The headset is charged sufficiently. The operating instructions of the computer is on hand. Enter pairing mode on this headset.
In this case, start over from step 1. The headset is already paired with 8 devices and another device is to be paired.

The headset can be paired with up to 8 devices. If a new device is paired after 8 devices are already paired, the paired device with the oldest connection time is replaced by the new one.
When the headset is initialized, all pairing information is deleted. The headset can be paired with multiple devices, but can only play music from one paired device at a time. Hint The above procedure is an example. For details, refer to the operating instructions supplied with your computer.
Charging cannot be done. Charging time is too long. The headset cannot be recognized by a computer. The remaining battery charge of the headset is not displayed on the screen of an iPhone, iPad, or iPod touch. Sound No sound Low sound level Low sound quality Sound skips frequently during playback. The noise canceling effect is not sufficient.

Can you give me the lowdown on it and why I should care? Dear AC, NFC is getting a great deal of attention as it becomes included in more smartphones, laptops, and other devices.
It's being hyped as The Next Big Thing that will change how we use our mobile devices: everything from shopping to interacting with your home and unlocking your car. Here's an overview of the current and potential uses of NFC. NFC stands for Near Field Communication, and, as the name implies, it's a set of close-range wireless communication standards.

Remind you of tap-to-pay credit cards or apps like Paypal "bumping" to transfer money? That's because NFC is the technology behind many new mobile payments types such as these. RFID waves can have very long ranges e. This makes NFC perfect for more secure applications like paying for things or securely logging in at a location.
How to use NFC function on my PC with Windows 10?
So transferring photos or contacts between devices is a common use of NFC see the "Android Beam" feature on many new smartphones. Many smartphones and new laptops have NFC chips. NFC World has an exhaustive list of all the phones around the world that are NFC-equipped available now, coming soon, with limited availability, and more categories. NFC chips are also embedded in "tags," which are stickers that your device can interact with.
NFC is most commonly associated with the "mobile wallet"—the idea that your smartphone will replace your cash and credit cards. In one tap or wave of your phone, you can pay for your groceries and redeem offers or coupons. You can store all major credit and debit cards in Google Wallet and get a "virtual MasterCard" that pays for your purchases in-store wherever those PayPass scanners are or online. The phone, tapped to the laptop, logged into a site and paid for an online purchase—no form-filling required.
Beyond mobile payments, though, there are a world of uses for NFC, including:. With programmable tags you can buy, you can tap your phone to a sticker on your desk, wall, car, or wherever to automatically change the settings, such as volume or Wi-Fi network, open an app, pair Bluetooth devices, and more. For example, you could switch to car mode when you get into your car, turn on the alarm app when you tap your nighstand, turn off the ringer when you get to your desk.
CNET has a few other great ideas like using an NFC tag on your washing machine to fire up a timer to tell you when to come back. Right now, NFC hasn't hit the mainstream yet in terms of usage, but it's the potential that's made it so popular.
Or, if nothing else, you'll look like a ninja when you fire up your favorite playlist with a wave of your phone.Keep in touch and stay productive with Teams and Officeeven when you're working remotely.

The Electrodog Showover at Instructables, shows us how do set it up. The video above is a quick demo of the process, and we imagine that if you have an NFC-enabled smartphone, you can do the same thing with your phone instead of another tag. The trick here is that instead of using NFC to just turn the power on or off to your computer, you can actually program the shield to enter your password so all you have to do is press enter when you swipe your tag.
You'll need a few things to make the setup work, including an Arduino Leonardo and Adafruit's NFC Shield, along with some extra tags and a soldering iron. In the video above, the setup is mounted on top of the desk—it'd be ideal to keep it somewhere under the desk or out of sight, just for a little obscurity. Don't get us wrong, it's not hard to type in a password, but if you have an auto-locking PC, or you lock your system every time you get up from it if you work in an office like my old job, for example, where an unlocked PC was an invitation for mayhemthis can help you get back to work quickly when you sit back down.

Description This contactless security smartcard for Dell laptops is specifically designed to take advantage of the convenient two factor pre-boot authentication feature offered on several models of Dell laptop. Although the Dell contactless reader is compatible with many types of contactless cards, only HID's iClass range offers the enhanced security of an encrypted session between the card and the reader and uses data securely stored on the card rather than a relatively insecure chip serial number CSN to protect your logon credentials.
Our Dell contactless security card is specially pre-programed to offer the maximum possible security, and needs no additional drivers or software installation other than the standard Dell-installed ControlPoint Security Manager and Wave Embassy Security Center applications.
After enrolling your contactless card you will be ready to enjoy secure 2-factor pre-boot authentication PBA as well as optional Windows login using cached credentials. Please see your laptop user guide and the following HID Application Note for more details of how to enroll your contactless card.
Note: This card will only work with Dell E- or Z-series Latitude or Precision laptops such as the E, E or Z that have a contactless smartcard reader built in underneath the palm rest. This should not be confused with the contact smartcard reader slot that is available on nearly every model of Dell laptops.
I want to write some small piece of software that would listen to this server and unlock my computer if the server tells my computer to do so.
How to 'NFC tap and send' function on windows 10?
I have not made the last part work as I don't know how to write such a software for either Mac or PC. Is it possible? If so, how? The NFC part is very simple but the unlocking part is more complicated than you think. Unlocking your computer should never be done programmatically because if your program can do it, then so can others. Not to mention that this 'program' is going to act based on communication between a remote server and itself.
This is a security nightmarethat has no use other than the experimental benefit. If you do enough research you'll find that locking not unlocking a computer is possible programmatically. Unlocking on the other hand is not easy. I thing another way of accomplishing this would be to do it the other way around. Have your phone store your password in an app that could pass it along to the computer. When you tap your phone to the USB device it "types" your password into the text box and the last thing the app does is "hit the enter key" Obvious security issue is if you are running the unlocker app it is essentially just constantly sending out your password I would like to note that Asus has launched a product that does this allows NFC login for windows 8, so it is possible - as far as how secure it is I don't know How are we doing?
