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.

How Bluetooth pairing with NFC works

In wireless communications, unlike cables that require a mere plug in, there is a shared medium that allows two ends of a connection to know each other before any interchange of data can occur. This implies prompting a device to search for other devices within its proximity to connect to, automating the sequence in that the next time the devices get within range of one another, this process just happens without intervention.

This is what we know as pairing.

It seems close to simple but it actually takes some time for a device to discover others. It is even made difficult if there are multiple devices within its range, and the automatic pairing after the first time will not effect if you are pairing with a device that you will never use again.

This is how NFC joins the race. NFC was first developed by Sony and NXP Semiconductors invented the later technology we see to-date, which enables short range communication between compatible devices while sending data over radio waves.

It can not exceed four centimeters, in comparison to Bluetooth which can reach up to thirty feet. One would take it for a disadvantage but close proximity is also an advantage when it comes to prevention of interference. In crowded locations where there are many devices trying to connect to each other, NFC can quickly connect two devices close to each other then shift the signal on to Bluetooth so that the device holders can move any further without breaking the connection.

This strict proximity ensures that exactly the two devices that you would wish to connect are the ones linked up. It is just enough to allow two Bluetooth devices to identify one another and establish a secure connection, a reason for Bluetooth device manufacturers opting to use NFC for Bluetooth pairing.

For instance, to connect your Bluetooth headphones to your smartphone, you just need to make sure that the headphones are powered on, your phone is unlocked and that both Bluetooth and NFC are enabled. Then tap the devices together, and you are good to go. You may need to ensure that both your phone and the headphones support the tap-to-pair functionality.

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.
