What is NFC? Here’s Everything You Need to Know

All today’s smartphones are equipped with NFC technology. Whether you realize it or not, your phone is likely to use NFC right now. But don’t worry – NFC uses minimal battery and processing power, offering a host of benefits that improve the functionality of your device.

Although it is widely used in peer-to-peer payment and data transfer apps, NFC has many more applications that can make your life easier. Read on to know how you can take full advantage of your phone’s NFC capability.

What is NFC?

What is nfc heres everything you need to know

NFC stands for near-field communication, and it allows phones, tablets, laptops, and other devices to easily share data with other NFC-equipped devices. It evolved from radio-frequency identification (RFID) technology. RFID is behind the security scan cards you find in the office every day or bypass the tollbooth on your morning commute.

NFC is very much like RFID, but NFC is limited to communications within about four inches, which is why if you are using Apple Pay or Samsung Pay you need to keep your phone close to a contactless reader. Most people consider the small scope of NFC to be a major security benefit, and this is one of the reasons why NFC has taken off as a secure alternative to credit cards. The technology can be used for more than buying coffee at Starbucks, however. NFC can also transfer data such as video, contact information, and photos between two NFC-enabled devices.

How does NFC work?

Unlike Bluetooth, NFC does not require any manual pairing or device discovery to transfer data. The NFC connection starts automatically when another NFC device enters the four-inch range already specified. Once in range, both devices immediately communicate and send signals to the user. There are huge possibilities with NFC. Listed below are the three major ways we already use NFC between devices.

Nfc payment

mobile payment

As consumerism is slowly transitioning into a cashless world, mobile payment has become a popular mode of transaction. Equipped with banks’ collaboration and biometric technology on most modern smartphones, mobile payment is safe and convenient. Placing your smartphone within four inches of a contactless reader in a store will ask for your digital wallet or passbook to pop up and confirm payment. With Apple Pay, this means placing your finger on the home button, which has the Touch ID function, or doubling your power button to scan your face with Face ID. It also works with Google Pay and Samsung Pay.

Sharing between Android devices

When two capable NFC devices are in range, a prompt will ask if you want to “beam” whatever content (video, contact information, or photos) is on-screen on other Android devices. Android devices have been able to use Android Beam for some time (since version 4.0 Ice Cream Sandwich), but this is a little-known feature, which may be part of the reason Google discontinued it. In Android 10, Android Beam no longer works, and Google is slowly replacing it with a nearby share, but the rollout is slow.

These passive tags do not require power and can be programmed with an application such as Tesar to perform certain tasks when scanned. For example, you can put one on your desk, and with a quick scan on the tag, you can set your phone to enable vibration, disable GPS, or just work-related notifications, among other options .

Which devices have NFC?

The list of devices equipped with NFC is increasing every day. To keep track of devices that leverage NFC technology, NFC World maintains a mostly up-to-date list of NFC-enabled phones. Many Android devices have NFC, and every iPhone since iPhone 6 is also feature-packed.

Every iPhone since iPhone 6

For a long time, Apple restricted NFC-equipped devices to purchase. However, the latest batches of iPhones including the iPhone 12, 12 Pro, 12 Pro Max and 12 Mini also support NFC tags via the Launch Center Pro app.

NFC was also added to the iPad range, starting with the iPad Pro, iPad Air 2, and the third-generation iPad Mini, but those devices won’t work with in-store contactless readers. For a full stop for all Apple devices that support the NFC and their limitations in the context of Apple Pay, see this support page from Apple.

Every device running Android 4.0 or later

If your device is running Android 4.4 or later, you can use Google Pay. If you have a Samsung device, you can also use Samsung Pay.

Android consumers who are using Android 4.4 to Android 9.0 can also use Android Beam for direct exchanges. With the program, you can swap a wide range of information including YouTube videos, contact information, specific webpages, and more. Enabling this service is simple; To run Android Beam, first open your phone’s settings. For Samsung Galaxy S10, follow the route: Adjustment > Relations > NFC and payment.

NFC technology has helped streamline public transport. Users can scan their NFC-enabled smartphones on buses or use them as metro passes. You can also add money directly to this virtual transport fund through an app, which can help you save time during your commute and ensure that you always have some cash where you need it. The technology is also capable of supporting loyalty cards. And then, there is also always the option of putting an NFC chip in your body. Wild, we know.
