Many of the latest smartphones and tablets now come with NFC (Near Field Communication) technology. This allows them to communicate with other NFC-enabled tags and devices when in close proximity.
If you’ve got an NFC-enabled device such as the HTC One X, the Samsung Galaxy S III, the Galaxy Nexus or the Nexus 7, there are a range of cool things that you can do using your handset. This includes using NFC to automate daily tasks, reading your electronic passport and sharing photos with friends and family.
In this article, we look at some of the things you can do with your NFC-enabled smartphone and tablet.
1. Automating Tasks
One of the most useful applications of NFC technology is to automate tasks and activities based on other NFC tags. Many of us now regularly come across NFC-enabled cards in our everyday lives – for example your Oyster Card for travelling around London contains an NFC chip inside. Other cards that might also have an in-built NFC chip include your work pass, student card, library card, credit card and club membership card.
One of the useful features of NFC is that every NFC-enabled card contains its own unique identifier. This unique identifier can be read by any NFC-enabled smartphone and can be used to automate tasks on your handset. For example, you could set up your phone so that it will automatically go silent when you tap it onto your work pass. Alternatively, you could have your phone check the latest travel news and to send a text home when you tap it onto your Oyster Card. It is possible to do configure almost anything on your smartphone to occur in response to a NFC tag.
In order to automate tasks using your smartphone and NFC technology, you’ll need an application such as NFC ReTAG (free, Android). This application works with all of the NFC-enabled cards you currently have. You can also buy additional NFC sticker tags online for around £1 each: these can be useful to place in your car or around the home for additional home automation. These are a great alternative to more expensive manufacturer solutions such as Sony’s SmartTags and Samsung’s TecTiles.
Using NFC technology, it is possible to set up your phone to check the traffic news whenever you tap it onto your Oyster Card.
2. Read Your e-Passport
As of March 2006, all British passports have been issued with an electronic NFC chip inside. This chip holds your personal information as well as facial biometrics and is embedded into the back page of your passport.
As e-passport chips simply use a NFC technology, it is possible to use your NFC-enabled smartphone to read your passport information. The NFC TagInfo application for Android can be downloaded for free from Google Play and supports e-passports. Simply place your NFC-enabled handset on your e-passport to download your personal details and photograph.
Note that for security reasons, e-passports contain some basic access control security. This stops other people from covertly reading your passport as they walk past. In order to read an e-passport through the NFC chip, you need to provide three pieces of information: your passport number, your date of birth and the expiry date of your passport. This information can be found on the inside back page of your passport and can be input into the application through the ‘Menu Button > Setup Access Keys’. Once configured, you will be able to access the electronic chip.
You can read the information from your e-passport with an NFC-enabled smartphone.
3. Share Photos, Videos & Business Cards
If you’ve got an NFC-enabled handset running Android 4.0 Ice Cream Sandwich or Android 4.1 Jelly Bean, it will support the ‘Android Beam’ feature. This allows you to transfer multimedia files and information such as contact details by tapping your handset onto another enabled device. This is a fun and fast way to share photos and videos: when two compatible handsets are tapped on each other, Jelly Bean will use NFC to initiate a high-speed file transfer over Bluetooth.
Alternatively, owners of the Samsung Galaxy S III have access to ‘S Beam’ which allows file transfers at speeds up to 300Mbit/s. ‘S Beam’ uses NFC and Wi-Fi Direct technology.
Consumers in the US can currently pay for items in-store using the Google Wallet application. In the future when Google Wallet or similar services are made available in the UK, it’ll be possible to pay for things in a shop or restaurant by tapping your handset on a reader at the till. This means faster payments without fiddly paper receipts to collate. It also means greater security compared to standard payments as your mobile phone can be secured with a security codes, facial recognition and can be remotely disabled in the event of loss or theft.
