Difference between NFC and Bluetooth

Ever thought what is the difference between NFC and Bluetooth? As technology improves every day, it is now becoming easier and easier to transfer data between devices. In recent years, wireless technology has exploded, offering a variety of effective ways to distribute media and data wirelessly.

NFC and Bluetooth have many similarities and significant differences. The frequencies that they use differ significantly from one another. This is crucial because more data can be transferred per second at higher frequencies. The wavelength of Bluetooth is approximately 176.8 times less compared to NFC. As a result, Bluetooth transfers data significantly more quickly than NFC does.

The simplicity of starting a transfer by just tapping two things together is what makes NFC so appealing. As with Bluetooth, there is no longer a requirement to pair devices. However, Bluetooth is more practical if the gadgets can't be physically connected because it has a considerably wider range

Bluetooth and NFC are the two best wireless communication technologies. Both of these technologies make use of radio waves to establish connections, communicate with devices across short distances, and for the transfer of various types of information.

The issue of security should also be considered. Unbelievably, Bluetooth can be used by hackers to access your phone. Hackers have a higher chance of accessing your phone because of Bluetooth's increased range. It's crucial to safeguard your Bluetooth-enabled gadgets from hackers because of this.

Read this article to find out more about NFC and Bluetooth and how they are different from each other.

What is Bluetooth?

Bluetooth is a wireless device that permits quick data transfers between stationary and mobile devices. At COMDEX 1999, Bluetooth made its debut as a consumer technology. It was displayed with the outrageously innovative MP3 player. It uses UHF radio waves in the 2.402 GHz to 2.480 GHz frequency band

Bluetooth was initially created to link wireless headsets to computers. Despite being found at the time, it didn't receive its formal name until 1998. Before the first cell phones attracted audiences, there was Bluetooth. In 1989, the Swedish telecommunications company Ericsson created it for the first time.

We almost never leave the house without our cell phones; they are always within reach. It is therefore the ideal addition to a system for access control. To connect the devices in Bluetooth, a manual setup is necessary. To pair the devices, you will typically need to input a PIN code and set up a few settings.

Bluetooth technology needs to be directly connected to the controller using software in order to function. More and more businesses are seeking methods to include smartphones into access control systems as smartphones become an indispensable part of our lives. The prevalence of Bluetooth-enabled phones will inevitably result in the development of digital keys.

What is NFC?

Another wireless technology is NFC, or near-field communication, which operates at a frequency of 13.56 MHz and enables close proximity communication between compatible devices. "Near Field Communication" stands for NFC. Similar to Bluetooth, this technology's main purpose is for exchanging data across short distances. NFC requires a minimum of two devices: one broadcasting and one receiving the signal.

The fundamental idea of RFID has indeed been carried over to NFC. When it refers to NFC, there are two parts: the reader and the tag

Due to the alternating magnetic field used by NFC technology, no power is released as a result of radio waves. By doing this, interference among similar devices or even any communication systems using the same frequency is avoided. It won't have as much of an impact on your battery as Bluetooth technology does. Ideally, you should only use it when it is on to avoid draining your battery.

In contrast, there is no requirement for verification while setting up an NFC connection, which is extremely simple. With NFC-enabled gadgets, all you have to do is turn them on and place them close together to communicate. NFC technology allows for rapid data transfer with no extra effort required.

According to some estimates, NFC is ten times quicker than Bluetooth. Speed does matter when discussing data transfer, though.NFC has a much shorter operating range than Bluetooth, which is 10 metres. Only a 4 cm communication connection is supported by NFC.

The technology known as RFID, or "Radio Frequency Identification," forms the foundation for NFC. NFC was authorized as an ISO/IEC standard in 2003.

Difference between NFC and Bluetooth

The following table highlights the major differences between NFC and Bluetooth −





Range up to 4 cm

Range up to 10 meters


It sends the data most faster way

It sends the data less faster way


Card Payments can be done

Only videos and images can transferred


More Safer

Less Safer


It used the Interacting electromagnetic radio fields

It uses the Direct radio transmissions

Communication Frequency

Range upto 13.56 MHz

Range upto 2.04 MHz


It can connect 2 devices

Only 8 devices can be connected at a time

Data Transfer Rate

The Maximum NFC can transfer is 424 kbits/s

The maximum Bluetooth can transfer is 1 – 3 Mbits/s


It follows the standards like ISO, ETSI, ECMA

It follows the only one standards i.e., IEEE

Battery Usage

It uses the Less battery

It uses the Less battery


Bluetooth and NFC appear to be identical at first glance. However, there are vast differences that exist below the surface. As a result, while NFC and Bluetooth devices are comparable in that they both use wireless transfer techniques, they differ greatly in other ways.

When it comes to file transfers, Bluetooth is faster, but NFC is more secure and has lower battery consumption. NFC is frequently used for access control as well as payments since it works best over short ranges to securely communicate small amounts of data.

In terms of overall superiority, that is a matter for each person to decide. Bluetooth, on the other hand, although less secure, offers a wider connection distance and is most frequently seen on wireless devices like headphones and speakers.
