NFC (Near Field Communication)
This term is used to describe the way in which contactless devices communicate with each other over a short distance. It’s a set of rules that determine how these devices interact within the 4cm range. It tends to offer a lower-speed connection in exchange for wireless or connection-less data transfer. It is already usable between things like; mobile phones, tablets, and any other similar smart device. You will likely have noticed already the prevalence of using these kinds of transactions. Some of the more notable common examples include travel cards like Oyster, payments using a credit/debit card or your mobile phone or when exchanging data between phones are short range.
Let’s get into some of the important features and benefits that NFC has to offer:
Benefits and Features
- Used for sharing small files and data when large transfers aren’t required.
- Low-speed internet connection expanding the range of shareable material.
- Tend to be used for things like contactless payments or identity documents.
- Very quick and efficient.
NFC in daily life
In our everyday life, we often see the use of NFC technology. Contactless cards payments can be one, use of entry cards in building is another, travel cards on public transport also. It’s simple and efficient design makes it usable in cases of high use, like transport which has high footfall or a card terminal which accepts many kinds of payment over the course of any given day.
NFC is rooted in radio-frequencies, which means that is can both supply power to and communicate with radio waves. This can be used for tracking or for validating. It has been a dominant form of intra-technology communication for much of the recent past, and whilst other tasks now move over to more powerful methods, much of what we do is still ran on NFC. One product that still very much uses NFC is Android devices. It’s available on almost every high-end phone that’s produced. The technology has worked in conjunction with another feature called Android beam which is set to be replaced in the future. You’ll need to keep the devices together when exchanging information or the connection will be interrupted. Because of the lower size of data you can send, you often cannot share videos or apps, but webpages or app locations in the play store.
Of course the biggest drawbacks are the short range over which NFC operates as well as the fact that it’s only allow a small transfer of data. On top of this, there are several models of smartphone or other smart device that don’t come NFC enabled. It’s quite difficult to main NFC technology for a company due to the pricing, so they will want to know it’s widely used to do so. With more and more technologies blossoming that do the same or similar things, NFC’s longevity is uncertain and that devalues the worth of NFC on devices generally.
