In today's world of wireless technology all we want is to securely transfer data from one device to another. We do not want to fall in the category of cyber attack victims. Users cannot always depend upon the wireless transfer through the internet. Therefore, more and more wireless technologies are developed for the convenience of the users. There are 2 such technologies that promises to make wireless transactions secure. Those are the NFC and Bluetooth. Bluetooth is technology used to exchange data between 2 devices while Near Field Communication (NFC) is a technology standard used for wireless data transmission. Most of the large smart phone manufacturing companies incorporate NFC and Bluetooth in their devices. In fact many devices use both of these technologies together for a secure file transfer. Furthermore both and the NFC and Bluetooth establish connection between 2 devices. Besides providing connections for transferring data they are entirely different in many aspects.
In this article, I will be mentioning about NFC Vs Bluetooth | 5 Differences between NFC and Bluetooth. At the end of this article, you will know which is the better form of wireless communication.
Let's get started,
1. Speed
By default NFC is low powered and has a very small range. Due to this ultimately its data transmission is also slower. In NFC the speed of data transmission is around 427Kbit/s which is significantly slower compared to other wireless technologies. However this speed is sufficient enough for the applications it is used for.
On the contrary, Bluetooth is designed to consume more power and serve over large range. Therefore, it is equipped with the highest data transmission speed which is around 2Mbit/s. Due to this, Bluetooth is ideal for sending large datas including videos, images and music.
Winner : Bluetooth
2. Security
In terms of security, NFC clearly outranks Bluetooth. Even though there are no any security measures taken in NFC, due to its very short range hackers may find it difficult to trace your transactions. Hence, NFC is ideal for making payments through credit cards involving sensitive informations.
Coming to Bluetooth, though it has many security features such as PIN authentication still it lacks on the side of security. Due to its large range, attackers can easily hack the signal which is being transmitted between devices.

3. Range
Range offered by a NFC is around 4cm. Which means that you cannot move freely with the NFC connected. However there are certain advantages due to this short range too. With this short range, users can ensure that their transactions are protected from attackers. Hence, NFC requires devices to be kept close to each other.
On the other hand, Bluetooth has a range of 5-10m. Compared to the NFC this range is significantly higher. Therefore, distance isn't an issue in Bluetooth at all.
Winner : Bluetooth
4. Usability
NFC connections are generally easy to establish and no any kind of authentications are required. What you have to do is, turn on the NFC, bring the devices close to each other and the data transmission occurs automatically.
While a Bluetooth requires a set of procedures to be done for the data transmission to take place. Generally you have to enter the PIN code and configure settings in order for pairing the devices. This makes Bluetooth a time consuming task. And also there are chances for it to not to get connected due to some technical glitches.
Winner : NFC
5. Power Consumption
Due to the fact that NFC is slower and utilizes a radio transmitter with low power, the battery life on the device is not that much affected. Moreover you can keep your device '' Always on '' with the NFC, still there won't be much battery drainage.
Comparing this to Bluetooth, it also consumes low amount of battery power. But still this number is greater compared to what NFC does. Typically you can notice your battery draining significantly if you keep the Bluetooth '' Always on ''.
Winner : NFC
