We now avail to you a selection of great uses of this technology, and explain to you how valuable it is to the next generation of smart devices.

Start up your PC

If a technology doesn’t make you lazy, then make the best of use in it. With just an NFC tag, you can use your Android device to wake up a Windows PC without pressing a button.

To do this, you have to open up the Windows Network and Sharing Center on your PC, click Change adapter settings. Select for Properties of your primary internet connection. Click the Configure button, and go on to the Advanced tab, look out for the “Wake on Magic Packet” option. Set it to Enabled.

After setting up the PC, you’ll need some apps to take you through the process much easily. WoL (Wake on LAN) for prompting the start up, Tasker for configuring the NFC tag, and an NFC Task Launcher – like Trigger – to complete the tag.

After downloading and installing the Wake on LAN app, open it and add a new device. Choose the name you want to use for the computer and fill in the MAC and IP addresses, after which you should save.

Cashless Payment of bills

Quick Tap is utilising the tech to do the business of delivering secure, easy, fast and efficient payments and access to control services. They install NFC tap to pay terminals at the client premises which users with NFC devices such as phones, cards, wristbands, and stickers can tap to make payment or access premises.

That’s the best of examples on how to use NFC to clear your bills without cash

Faster device pairing

With most high end smart phones now supporting the short range communication, one can use NFC to quickly connect two devices close to each other in less than one tenth of a second – using inductive coupling.  They can then shift the signal on to Bluetooth so that the device holders can move any further without breaking the connection. This can be for file transfer, for linkage, or even compatibility.

NFC lets you share almost everything with your friends via their NFC-powered devices. Whereas it’s as easy as that, Sharing apps allows the user access to the app’s Play Store page for downloading.

Sharing a contact prompts the receiver about which account to create the new contact in and the contact info will be displayed in Contacts app.

With the Trigger app we listed above, you can be guaranteed of a link to almost every tag out there.  Just make a simple contact between your device and the tag. This tag could be your door lock, your music player, your light switch, name it.
