Near-Field Communication (or NFC) has been around, in some form, for decades. However, thanks to the growing popularity of smart phones and mobile devices, NFC is now being widely used to make it even easier for tech-savvy individuals to share, shop, and stay up to date anytime, anywhere. In this guide, we'll take an in-depth look at the basics of NFC technology, how it works, and what the future holds for Near-Field Communication.
What is NFC?
Near-Field Communication technology allows devices to transmit data to one another within a short range (a few centimeters, at most). Essentially, if your smart phone is equipped with a NFC chip, then it can access data that is stored in another NFC chip that is nearby. For example, there are certain Near-Field Communication chips that enable you to simply place your tablet or mobile phone against a cash register and purchase an item without using your credit or debit card. As such, NFC has the potential to make our tech-centric lives a bit less complicated, thanks to the variety of processes it can carry out.
How Does NFC Work?
Near-Field Communication technology is based upon radio wave transmission. Devices that are equipped with NFC chips are able to transmit data through electromagnetic induction. Near-Field Communication is able to operate in three distinct modes: reader/writer, peer-to-peer, and card emulation. In reader/writer mode, the NFC device can gather and write data onto a smart tag. In peer-to-peer mode, it allows for data exchange between two NFC-equipped devices. Card emulation mode enables the NFC chip to “emulate” a smart card, whereby it can be used to make payments and access schedules, etc.
What the future holds for Near-Field Communication technology:
The versatility of Near-Field Communication technology makes its future implications virtually limitless. Here are just a few ways that NFC technology is utilized today, as well as some functions that Near-Field Communication may be used for tomorrow:
• NFC phones allow users to “check-in” when they visit certain restaurants, shops, or local hot spots, so that their friends can meet up with them via social media sites. All you need do is swipe your NFC-equipped phone to let your virtual circles know where to find you.
• Those who own NFC devices can pay for goods or services quickly and conveniently. They can also access important information, such as bus schedules or transmit maps, if NFC chips are included on city signs or smart objects. In many ways, Near-Field Communication allows users to gather data that can make it easier and safer to travel.
• Businesses will now have the ability to integrate NFC chips into their marketing materials. For example, they can include NFC technology in signage in order to give customers the opportunity to quickly scan the chip and access the business' information. As such, it's thought that NFC may play an important role in the future of business promotion.
• The future may very well involve NFC-enabled identification systems. For instance, you may be able to swipe an NFC device in order to check in for a flight or to get through customs. Your important information will be stored on the NFC device and then transmitted when necessary. As such, you won't have to carry tangible forms of identification, which may greatly reduce identify theft and stolen cards.
• Some NFC developers have already begun using near-field communication technology to create locks. For example, you can use your NFC device to unlock your front door or to get into your car. As long as you are within close proximity to the lock itself, you will be able to gain entry. Worrying about misplacing your keys will be a thing of the past.
There isn't any doubt that technological advances are becoming an essential part of our lives. We rely upon mobile devices to keep in touch with loved ones, and use computers on a daily basis to shop and conduct business on a global scale.
All signs point to NFC technology playing an integral role in the future of our world, particularly in regards to data sharing, payment processing, and multimedia marketing.
