How to use NFC: Some Tips for You
In this period of time, touch and pay services are essential for our survival. You no longer have to endure long queues in banking halls or ATMs to withdraw cash for daily use.
These services are quite useful as they are accessible anywhere, anytime, barring the possibility of technical interruptions. The issue of carrying with you huge loads of cash is all but eliminated as long as you embrace this technology.
The main examples of these services include Android Pay and apple Pay.
How NFC Works
So how does it work? It is NFC which stands for Near Field Communication. This is simply a data transfer method which relies on wireless technology.
All it does is detect and facilitate the technology which is at a reasonable proximity. The amazing part of this is that it does not require internet connectivity to operate.
It seems complicated, doesn’t it? Well, you will be surprised as to how simple this technology is. It started as radio frequency identification (RFID). This is an NFC chip which partly operates as a wireless link.
Another chip activates this one and results in data transfer between the two devices. These devices have to be in close proximity, preferably centimeters apart.

Low Power Chips
Unlike Bluetooth devices, pairing codes are not necessary. Instead, it utilizes extremely low power chips. The passive devices are powered by the electromagnetic field which will be emitted once the device comes into the required range.
This feature of power efficiency is one of the reasons it is preferred as compared to other data transfer methods.
The NFC technology has quite a fast transmission frequency as compared to other data transfer methods. The rate of frequency can be as high as 425 kilobits per second.
For the Android NFC, you can use it with programmable NFC tags. You can also use it on contactless payment systems which are compatible.
The most common use of NFC is mobile payments. Other uses include the sharing of pictures and automating homes. This article is going to analyze deeper on how to use the NFC technology.
Programming NFC tags
This function will depend on technical prowess on the software. If your understanding is not deep, you can program the tags to perform simple tasks. These include setting timers, reducing your phone’s screen light and activate wireless tethering.
You can also program the tags to launch apps. However, this depends on your location for it to be successful.
If your technical knowledge is deep, you may program the tags for complex tasks. For instance, you may program them to boot your PC.
You may also program the tags on your business card such that new contacts are saved in an instant.
Sharing your Wi-Fi Network
Coming up with a strong Wi-Fi password can be quite complicated. You have to dig really deep to come up with a non-penetratable combination.
Set up the tough password and then an embarrassing situation may present itself. Imagine that your business associates have come over for a short visit and request for your Wi-Fi password.
You may find yourself in an awkward situation either because either because you have forgotten your complicated password or it is too embarrassing to share. Well, an NFC tag may be your savior.
You may program the tag to log into your Wi-Fi network through the simple act of swiping. The associates would use your network without knowing the password. How convenient is that!
They would however need an NFC reader app on their phones, which is normally free in the playstore.
Setting up a new smartphone
You can set up your new smartphone using the feature Tap & Go. This feature is mostly offered in Android lollipop.
This feature lets you move your apps straight from the old to the new phone. You can also move your Google accounts through this feature. Once you do this, you will not find it necessary to reinstall the accounts as well as the apps.
Note that you may redeem yourself if you skip this step in the set up process. You can restore the factory settings and repeat the whole process.
Mobile Phone Payments
This is probably the main application of NFC. The main service providers include Samsung Pay and Android Pay. These services enable you to store your credit cards such that you swipe your smartphone instead of using the actual credit card.
To keep up with the competition, major credit card companies such as Visa have joined the fray. They have introduced Visa payWare and Mastercard PayPass.
You can use NFC in sharing content with your peers. This includes photos, contacts, and videos and so on. This is especially fun when you are with your fellow android users. This is because sharing stuff is the simplest of tasks. All you have to do is tap the back of your cell phones together. Easy, isn’t it?
Your phone will need to have android beam, which should be on. You will not have the hustle of pens, papers and USB cables.
Think of the joy you will experience when you instantly share information which has just been released.
Despite all its wonderful uses and conveniences, NFC technology has its own cons. The main issue is security concerns.
The smartphones we use on a daily basis are practically portable mini-computers. They are therefore prone to hacking and other forms of cyber-attacks.

Hackers may use NFC software to gain access to sensitive information on your phone. This information includes credit card details and your email messages. In fact, most governments have a sense of paranoia when it comes to approving the use of NFC technology in their departments.
Another major issue you may encounter is company policies. Some companies may have reservations about integrating the NFC technology into their daily activities.
Maybe the company may have entered into similar agreements with rival companies and allowing NFC usage would be a breach of contract. You may therefore find it impossible to use it at your workplace cafeteria.
Despite these shortcomings, I find it hard to imagine a life without NFC technology. So, go ahead and give this innovative technology a shot.
