NFC Bluetooth pairing is a technology that has been around for a few years; it has been used in a number of devices such as mobile phones and laptops. You may wonder what NFC Bluetooth pairing is and what benefits it offers.

NFC Bluetooth pairing is a technology that uses Near Field Communication (NFC) to pair two devices, such as a mobile phone and a laptop. NFC is a short-range wireless technology that allows two devices to communicate when they are close together, typically within a distance of four inches.

In this blog post, I will discuss what NFC Bluetooth pairing is and the various benefits that it can provide. I will also talk about how to set up NFC Bluetooth pairing on your device.

How Does NFC Work?

NFC uses electromagnetic induction to communicate between devices. When two NFC-enabled devices are brought within proximity of each other, an electromagnetic field is generated. This field can be used to send data between the two devices.

NFC is a very short-range technology, with a maximum range of four inches. This means that it can only be used to communicate between two very close devices.

NFC is a power-efficient technology that does not require much battery power to operate. NFC is also very secure, as the data transmitted between devices is encrypted.

5 Benefits of NFC Bluetooth Pairing?

There are many benefits to using NFC Bluetooth pairing.

1. Convenient

NFC is a very convenient way to pair two devices. It is much quicker and easier than traditional Bluetooth pairing, which can often be slow and cumbersome.

4. Mobile Payments

Another common use for NFC is paying for things. NFC-enabled credit cards and mobile wallets can be used to make payments at NFC-enabled terminals.

Samsung Pay, Android Pay, and Apple Pay are all examples of NFC mobile payment systems.

5. Public Transport Access

Public transport in many cities, including London, New York, and Beijing, now use NFC for ticketing. This is convenient as you can simply tap your phone on the NFC reader to pay for your fare.

6. Gaming

Nintendo’s Amiibo figures use NFC to connect to games. This allows you to unlock content and save data to the figure.

An Amiibo is like a physical save file you can take to a friend’s house.

7. Home Automation

A few home automation systems, such as Home Assistant and Apple’s Homekit, use NFC to trigger actions.

For example, you could tap your phone on an NFC tag to turn on the lights or unlock the door.

What is Bluetooth NFC pairing?

NFC MAKES BLUETOOTH PAIRING AS SIMPLE AND EASY AS PLUGGING IN A CABLE. But it’s enough data to allow two Bluetooth devices to identify one another and establish a secure connection. That’s why some Bluetooth device manufacturers have started to use NFC for Bluetooth pairing. The way it works couldn’t be simpler.

What is Bluetooth Secure Simple pairing?

Introduced in the Bluetooth 2.1 specification, Secure Simple Pairing (SSP) fixes all of the issues of the previous pairing method, and makes pairing Bluetooth devices simpler than ever. Stronger security also means new challenges for Bluetooth engineers.

Is NFC more secure than Bluetooth?

NFC tends to be more secure than Bluetooth, as it operates on a shorter range allowing for a more stable connection. Therefore, NFC tends to be a better solution for crowded and busy places, where a lot of different devices are trying to communicate with each other, creating signal interference.

Can NFC and Bluetooth work together?

When used together, NFC and Bluetooth Beacons work together to enable retailers and brands to engage throughout the stages of a shopping journey.

Does NFC require pairing?

One of NFC’s biggest strengths is that it does not require pairing or manual input to establish a connection — tapping takes less than a second.

Does NFC work with Bluetooth?

In fact, NFC can work directly with Bluetooth. For instance, instead of going through this process to pair your phone with Bluetooth speakers, you can simply tap the phone to a speaker, let the devices use NFC to exchange the pairing data, and you’re set.

Is Bluetooth pairing secure?

Bluetooth is also often insecure by design, which is exactly what you want for low-security uses like pairing your phone to a speaker or headset. The BR/EDR (Enhanced Data Rate) protocol can use a PIN to confirm connections, but often uses the “Just Works” connection system, which dispenses with this step.

Is Bluetooth pairing encrypted?

To deter hacking Bluetooth uses encryption based on security protocols called the SAFER+ block cipher. This technical term is complex to explain but essentially it’s based on encrypting data using custom algorithms.

Can you be hacked through NFC?

NFC is a useful technology for certain functions. But it’s not without its security risks. Because it lacks password protection, it’s possible for hackers to access NFC data. They can even do this without you being aware of it.

Is NFC a Bluetooth?

NFC is the abbreviation for Near Field Communication. It is a wireless touch technology that pairs two devices quickly without the physical pairing process. NFC is a newer technology than Bluetooth, though the technology used is older. It sends radio waves using RFID (Radio-frequency Identification).

Is NFC and Bluetooth the same?

NFC is great for transferring small amounts of data over a very short distance and is used mostly for wireless payments and access cards. Bluetooth allows for a more extended range of connectivity and devices such as cellphones, speakers, and headphones commonly use it.

Зачем наушникам и колонкам нужна технология NFC и как ее использовать

Беспроводный интерфейс Bluetooth настолько прочно вошел в нашу жизнь, что представить без него современный смартфон уже трудно.

В большинстве случаев он используется для передачи звука: от источника сигнала (смартфона, планшета, ноутбука) на колонки, наушники или гарнитуру.

Как и в случае с Wi-Fi, количество устройств, использующих Bluetooth, в некоторых местах просто зашкаливает. Пользователю приходится искать свой гаджет в длиннющем списке «конкурентов». И вот тут на помощь может прийти NFC.

Что это за технология

NFC изначально разрабатывалась для бесконтактных платежей. Прежде чем она заняла свое законное место в мобильных девайсах, прошло немало времени: впервые этот интерфейс был представлен аж в 2003 году.

Если для других беспроводных технологий их создатели стремятся обеспечить как можно больший радиус действия при минимальном уровне сигнала, то здесь, напротив, его целенаправленно урезали.

Зачем? А затем, чтобы исключить возможность несанкционированного подключения. Речь ведь идет о святая святых деньгах.

Поэтому то, что у всех остальных считается недостатком, здесь стало достоинством. И именно это качество оправдывает появление NFC модуля в наушниках.

Звук не передается через NFC

Именно так: данный интерфейс не используется для передачи аудиосигнала: он, как и при привычном варианте подключения, идет через Bluetooth. NFC для подобных задач не годится от слова совсем.

Мало того, что в гипотетическом случае такого его использования смартфон пришлось бы держать постоянно у самого уха, так еще и скорость обмена данными у него весьма скромная.

Теоретически, файлы передавать можно, но на практике никто этого не делает: есть более простые и удобные способы.

Речь идет исключительно о быстром сопряжении устройств. Ведь чтобы подключить гарнитуру к смартфону, достаточно просто поднести ее к задней панели девайса.

Любое Bluetooth соединение будет тут же разорвано, а вместо этого аппарат подключится к вашему гаджету.

Как настроить сопряжение

В Android процедура не такая уж сложная, хотя повозиться с менюшками все же придется – никуда от этого не денешься.

По умолчанию считаем, что и наушники, и смартфон имеют необходимый модуль, иначе говорить просто не о чем.

Изначально функция NFC в смартфоне неактивна, ее требуется включить, передвинув ползунок в соответствующем пункте Настроек. В зависимости от модели его конкретное положение может различаться. Обычно он находится в пункте Подключенные устройства или Connected devices.
