You are certainly quite familiar with the term NFC.\u00a0True, this feature which stands for\u00a0Near Field Communication<\/a><\/em>\u00a0is a kind of connectivity technology.\u00a0NFC is the same as Bluetooth, Infrared, and WiFi, its function is to connect devices to one another at a certain distance.<\/p>\n

However, there is something that makes NFC seem special over other types of connectivity, and its function is even more important.\u00a0The reasons will be discussed in the next point.\u00a0As proof of how important this feature is, now many\u00a0cellphones with NFC\u00a0are being sold.\u00a0Not only expensive cellphones, but also affordable cellphones.<\/p>\n

As of October 1, 2017, the Indonesian government has even decided that NFC is the technology that must be used for toll road payment transactions.\u00a0This wireless communication system technology is used to implement non-cash transactions via electronic money (\u00a0e-money<\/em>\u00a0).<\/p>\n

A Brief History of NFC and How it Works<\/h2>\n

NFC<\/a> is arguably the youngest age than Bluetooth, WiFi, and Infrared.\u00a0However, this technology is also not new.\u00a0In short, NFC was initiated by two companies, namely Sony and Philips Semiconductors in 2002.<\/p>\n

Both companies want to create simple technology for the benefit of advertising and industry.\u00a0In this case, identification, authentication and tracking.\u00a0Two years after the patents and technical outlines were made by Sony and Philips, the NFC forum was formed.\u00a0At that time, Nokia also joined.<\/p>\n

The joining of Nokia in the NFC forum is a sign that this feature will be brought to mobile phones.\u00a0So this feature began to be presented to Nokia phones, long before the popular Android and iPhone era as it is now.\u00a0Uniquely, the world’s first mobile phone with NFC is not Nokia, but the Panasonic P506iC which was launched in 2004.<\/p>\n

Nokia’s commercial mobile phone with NFC features was only released in 2006, namely the Nokia 6131. \u200b\u200bMeanwhile, the first Android phone with NFC appeared in 2010, namely the Samsung Nexus S. Meanwhile, Apple only injected NFC in 2016 through the iPhone 6.<\/p>\n

How NFC works is actually simple.\u00a0NFC utilizes an electromagnetic radio field with a specific frequency of 13.56 MHz at a distance of less than 10 cm.\u00a0This is what makes it different from Bluetooth and WiFi.\u00a0The reason is, Bluetooth and WiFi take advantage of radio transmission over a wide radius.<\/p>\n

Well, NFC can work if there are two types of devices connected.\u00a0The two types of devices are active devices (initiators) and passive devices or target devices.\u00a0In this case, the active device is\u00a0a smartphone<\/em>\u00a0, while the passive device is an NFC tag or card with an NFC chip.<\/p>\n

Active devices are tasked with reading data or exchanging data with other active devices.\u00a0Meanwhile, passive devices can only store data.\u00a0Therefore, NFC is actually similar to\u00a0barcode scanning<\/em>\u00a0tools in supermarkets.<\/p>\n

Data transfer rates via NFC range from 106 to 424 kbit\/s.\u00a0This means that large data transfers are very inefficient.\u00a0The purpose of NFC was not created for big data transfer, but practicality and security.\u00a0After all, this technology is also cheap.<\/p>\n

That’s why NFC is now more popular than Infrared, even though both technologies have the same characteristics of transferring data over short distances.\u00a0NFC is practical because a connection can be established in any way, as long as the two connected devices are within the right distance.<\/p>\n

Meanwhile, the connection in infrared can only occur if the two devices (source and receiver) are in a straight line.\u00a0Then, NFC is safe because it supports data encryption with the SSL (\u00a0Secure Socket Layer<\/em>\u00a0) protocol.\u00a0Infrared has no security protocol.<\/p>\n

Then, NFC is cheap because the passive device can be formatted (erase and write) repeatedly to fill in data as needed.\u00a0In addition, NFC passive devices also do not require a power source from the battery and so on.\u00a0NFC can also be integrated with Bluetooth or WiFi.<\/p>\n

NFC Functions<\/h2>\n

Well, now you know a brief history and how NFC<\/a> works.\u00a0The next discussion is the functions that you can do through a\u00a0smartphone<\/em>\u00a0that supports this one feature.\u00a0However, first make sure you know\u00a0how to activate NFC on your cellphone\u00a0before you can try out its functions one by one as follows.<\/p>\n

1. Sending Data<\/h3>\n

Sending data is the most basic function of any type of connectivity, and NFC is no exception.\u00a0At the beginning of its appearance, NFC was identical to the transfer of contacts, aka phone numbers.\u00a0Instead of writing down phone numbers one by one and then saving them, it’s more practical if you stick two phones that have NFC features together.<\/p>\n

With just one touch, the phone number is instantly sent from one phone to another.\u00a0In addition to contacts, other files can also be sent by mobile phones via NFC.\u00a0For example, photos, URLs or links, documents, to locations, either to other mobile phones or to laptop computers.\u00a0However, remember, NFC transfer speed is not fast.<\/p>\n

Make sure the file size you want to send is not too big.\u00a0On Android phones, sending files via NFC is facilitated by a feature called Android Beam.\u00a0Unfortunately, since Android 10 was released, the feature of sending files via NFC has been removed and replaced with Nearby Share – similar to Apple’s AirDrop.<\/p>\n

2. Checking and Replenishing Electronic Money Balance<\/h3>\n

\"With<\/p>\n

As explained in the first paragraph, NFC is increasingly popular in Indonesia thanks to the\u00a0cashless<\/em>\u00a0policy for transactions at toll road gates.\u00a0Therefore, every driver who wants to access toll roads must have an e-money card.<\/p>\n

Most of today’s ATMs also support the function to check and top up e-money card balances.\u00a0It’s just that, it turns out that this function can be done by HP with NFC.\u00a0You can also check and top up your e-money card balance anytime and anywhere.<\/p>\n

3. Make Payment<\/h3>\n

Shopping at a shopping center is the best if you use a debit card.\u00a0You don’t have to bother queuing to the ATM and taking money according to the funds you budget for shopping.\u00a0It’s just that, it will be even more practical when the debit card is connected to\u00a0a smartphone<\/em>\u00a0.<\/p>\n

Ease like this certainly becomes a reality thanks to the NFC.\u00a0Just stick your\u00a0smartphone<\/em>\u00a0on the NFC of the payment receiver at the mall, the transaction is done.\u00a0Some manufacturers also make payments via cellphones with supporting applications, such as Samsung Pay from Samsung and Apple Pay for iPhone phones.\u00a0The two applications can also be connected to a digital wallet account.<\/p>\n

4. Access Card Emulation<\/h3>\n

Today’s modern hotels and apartments choose access cards to replace conventional keys.\u00a0This access card is used to open the door and a kind of ticket so that users can use the elevator.\u00a0Well, the data contained in this access card can actually be transferred to a\u00a0smartphone<\/em>\u00a0that features NFC.<\/p>\n

The cool term is emulation.\u00a0That way, your cellphone can be used to open the door of a hotel or apartment.\u00a0Likewise when you want to use the elevator.\u00a0The existence of this emulation feature makes some manufacturers call their mobile phones have multifunctional NFC.<\/p>\n

5. WiFi Network Authentication<\/h3>\n

You will often be asked to enter a password when trying to connect your cellphone to a new WiFi network.\u00a0Such an event is natural for you to experience because the password is one method so that WiFi is not accessed by just anyone.<\/p>\n

However, some public places such as hotels are now using a tool called a WiFi porter so that visitors no longer need to fill in passwords manually.\u00a0The device stores passwords that can be read by NFC-enabled mobile phones.\u00a0Visitors just need to hold the phone closer to the WiFi Porter, then the phone is directly connected to the WiFi network.<\/p>\n

6. Recommend Applications<\/h3>\n

When hanging out with friends, there are topics that you talk about.\u00a0For example, about applications that are currently hits or mainstay applications to increase productivity.\u00a0You can of course have the application by asking your friends for his name.<\/p>\n

However, NFC makes things even simpler.\u00a0Without having to manually type the name into the Google Play Store or Apple Store, your phone will automatically go to the download link for the application in question.\u00a0This is the function of NFC in recommending applications to other devices.<\/p>\n

7. Running Applications on Other Phones<\/h3>\n

\"\"<\/p>\n

Not only recommending applications, through NFC, a phone can actually run applications installed on other phones.\u00a0The condition, of course, is that both phones have the same application.\u00a0The ability to run applications on other devices is utilized by a number of technology manufacturers.<\/p>\n

Especially for creating interconnectivity or connection to multiplatform devices.\u00a0Manufacturers like Huawei are taking advantage of NFC to make laptops and\u00a0smartphones<\/em>\u00a0connect\u00a0seamlessly<\/em>\u00a0.\u00a0Laptops can not only run applications on HP, but also open and copy data, as well as reply to messages and make calls.<\/p>\n

8. Check-in<\/h3>\n

Check-in<\/em>\u00a0is another basic function that must be able to be done since NFC was initiated.\u00a0As the name suggests,\u00a0check in<\/em>\u00a0is useful for notifying that someone is at certain coordinates.\u00a0This function can be applied such as when people\u00a0check in<\/em>\u00a0at a hotel or\u00a0check in<\/em>\u00a0in various public places.<\/p>\n

9. Wireless Charging<\/h3>\n

Charging wirelessly does not mean that electrical power can be transmitted through waves.\u00a0However, power is transferred through two sticking objects.\u00a0Cool language is induction charging.\u00a0In this case, the back cover of the phone becomes an object that is inserted a special device so that it can conduct electricity to the battery.<\/p>\n

Well, in 2020, the NFC forum approved a new idea regarding wireless charging via NFC.\u00a0According to a number of experts, active devices on NFC can indeed deliver power to passive devices (NFC tags).\u00a0However, the power delivered is not great.\u00a0It could be that in the future there will be phones with wireless charging support via NFC.<\/p>\n

10. Ordering Food and Other Functions<\/h3>\n

NFC has a function that is quite unique in Australia. In the Kangaroo Country, NFC is used as a tool to order food for moviegoers.\u00a0Visitors just open a food ordering application, choose a meal, and touch their cellphone to the arm of the chair where they are sitting.<\/p>\n

Not long after, the food will be delivered to the customer’s seat number.\u00a0Another unique function of NFC is an intermediary to connect the phone to other devices.\u00a0For example, keyboard,\u00a0speakers<\/em>\u00a0,\u00a0headphones<\/em>\u00a0, and alarms.\u00a0In 2012, the Japanese company,\u00a0Elecom\u00a0, created an NFC-enabled keyboard, for Android devices.<\/p>\n

Well, that’s the explanation of 10 NFC functions that are owned by today’s\u00a0smartphones<\/em>\u00a0.\u00a0Of the 10 functions that have been described, which one have you used often?\u00a0If there are other functions beyond what we have described, you can write them in the comments column!<\/p>\n","protected":false},"excerpt":{"rendered":"
