NFC vs Bluetooth, what are the differences?

If we are talking about BluetoothWe talked about wireless connection technology used by the mobiles of the first decade of the 2000s to share contacts, images and music. As has evolved to add new features and reduce consumption, its use has been extended to speakers, wireless headphones and smart watches.

Another wireless connection technology is NFC. Although many users generally confuse them, both have very different functions and uses, because everyone has a different mission.

What is Bluetooth

Bluetooth is the first wireless data transmission technology developed in 1989. As we commented above, it was initially developed to correspond to two wireless devices to send all data types.

At the time of the publication of this article, it is in version 5.3 and we can find it in all types of devices, mobile phones in tablets, via headphones, computers, location beacons, speakers and car devices.

What is NFC

NFC is also a wireless connectivity method. Unlike Bluetooth, it is not necessary to match the devices to use them. Everything you have to do is Bring them closer Enough from there, its name near communication in the field (which we can translate to be understood as a communication on the narrow field).

On the market, we can find devices that include the chip Passive NFC Y NFC active. Devices with a passive NFC chip can only send information such as access cards. The Active NFC chip allows both sending and reception data. This type of chip is that of smartphones and mainly in payments.

Differences between NFC and Bluetooh

The first and main difference that we can find in both technologies is in its beach beach. While Bluetooth Technology has a range between 10 and 20 meters, NFC technology does not work beyond 4 cm.

Due to their scope, the use of each of them is different. While Bluetooth is used to send data and sound to other devices, NFC technology is used to make payments from a mobile, beacons and access cards.

Another important difference between the two types of connection is found when sending data. Bluetooth is used to send all data types, sound files, because it is able to make speeds up to 2 MB / s. An NFC chip, as we have commented above, is used to send data that occupies very little space from there that their transmission speed is located at 424 kb / s.

So that the two work together on the same device without colliding, they use different Frequencies. NFC works at the frequency 13.56 MHz and Bluetooth in 2.4 GHz.

The last difference between the two wireless connectivity technologies that we can highlight is the number of devices that can be associated. A Bluetooth device can be twinned with up to 8 different devices, while the NFC chip is limited to two.

What is the best?

As we were able to check after reading this article, it is not a question of seeing what is the best technology of Wireless connectivity. The two were born and work in completely different ways, so it cannot be said if one is better than the other in certain circumstances because they do not offer the same functions.
