We live in an increasingly wireless world. Beacons and NFC (Near Field Communication) are often mentioned in the same breath, whether in attendance records, cashless payments or access control. In the world of proximity technology, NFC and Bluetooth beacons are two of the most commonly used options, and both of these beacons offer unique advantages.
Before determining which beacon type is best for you, you should be aware of several key distinctions between NFC and Bluetooth beacons. In this article, we’ll provide a comprehensive comparison of NFC and Bluetooth beacons and help you decide which one is the best fit for your needs.
What is an NFC Beacon?
In close proximity, two devices can share data thanks to the short-range wireless communication technology known as NFC. NFC is commonly used in smartphones and credit cards for contactless payments, but it can also be used for other applications, such as access control and information retrieval.
An NFC iBeacon is a small device that broadcasts a signal containing information that can be read by an NFC-enabled device. NFC beacons typically have a range of just a few centimeters, making them ideal for applications where proximity is essential.
What is Bluetooth Beacon?
In comparison to beacon NFC, Bluetooth allows for the exchange of data between two devices over a greater distance. Bluetooth technology is commonly used for wireless headphones, speakers, and other devices, but it can also be used for proximity applications.
A Bluetooth beacon is a small device that broadcasts a signal containing information that can be read by a Bluetooth-enabled device. Bluetooth beacons typically have a range of up to 100 meters, making them ideal for applications where distance is important.
Comparison Between NFC Beacon and Bluetooth Beacons
Range and Location Accuracy: One of the most significant differences between NFC and Bluetooth beacons is their range and location accuracy. NFC beacon technology is perfect for situations where proximity is crucial because its normal range is only a few millimeters. Bluetooth beacons, on the other hand, can have a range of up to 100 meters, making them suitable for applications where distance is important. However, the location accuracy of Bluetooth beacons can vary depending on factors such as interference and signal strength, whereas NFC beacons have higher location accuracy due to their short range.
Data Transfer Speed: Another important difference between NFC and Bluetooth beacons is their data transfer speed. NFC has a maximum data transfer rate of just 424 kbps, while Bluetooth beacons can transfer data at speeds of up to 2 Mbps. Because of this, Bluetooth beacons are perfect for applications that call for quick data transfer, such as asset tracking or real-time location services.
Power consumption: NFC gadgets often use less power than Bluetooth ones. It uses a low-power radio transmitter and receiver to function and has little to no impact on the device’s battery. As a result, NFC can be left constantly “ON” without significantly reducing battery life.
Battery Life: When deciding between NFC and Bluetooth beacons, battery life is still another crucial aspect to take into account. NFC beacons typically have a longer battery life than Bluetooth beacons due to their lower power requirements. This makes NFC beacons ideal for applications where battery life is a concern, such as access control systems or loyalty programs.
Compatibility with Devices: Compatibility with devices is another important consideration when choosing between NFC and Bluetooth beacons. Most modern smartphones are NFC-enabled, which means they can read NFC beacons without the need for additional hardware. However, Bluetooth beacons require Bluetooth-enabled devices to read their signals, which can limit their compatibility with certain devices.
RFID Compatibility: NFC is more practical to utilize with an existing RFID-enabled access control system because of its unique capacity to interact with passive RFID tags. Bluetooth, on the other hand, is not compatible with RFID and therefore not as flexible as NFC.
Cost: The cost of NFC and Bluetooth beacons can vary significantly depending on the manufacturer and the specific features of the device. However, in general, NFC beacons are less expensive than Bluetooth beacons due to their simpler design and lower power requirements.
Security: Finally, security is an important consideration when choosing between NFC and Bluetooth beacons. Both types of beacons can be vulnerable to hacking or unauthorized access, but Bluetooth beacons are generally considered to be more secure due to their encryption capabilities.
Comparison among RFID, NFC and BLE beacons
Like NFC and BLE, RFID is also a beacon with short-range technology, a wireless method that can be used to track items and interact with customers in retail stores. The main differences between these beacons are the frequency, range, data transfer, power source, and security. After reading the following comparison table, you’ll most likely understand them better.
As can be seen from the above table, RFID beacons use radio waves at a frequency of 13.56 MHz and have a short range of a few centimeters. They are passive devices that rely on an external reader to power them up and communicate with them. RFID beacons have a small data capacity and are commonly used for asset tracking and inventory management.
NFC beacons also use radio waves at a frequency of 13.56 MHz and have a similar range to RFID beacons. However, they are two-way communication devices that can exchange data with NFC-enabled smartphones and other devices. NFC beacons have a slightly larger data capacity than RFID beacons and are commonly used for access control and payment transactions.
Bluetooth beacons use Bluetooth Low Energy technology and have a much longer range of up to 100 meters. They are battery-powered devices and have a medium data capacity. Bluetooth beacons are commonly used for indoor navigation, advertising, and marketing applications.
In terms of security, RFID beacons have the lowest security, while Bluetooth beacons have the highest security. As for the cost, Bluetooth beacons are relatively cheap, while the price of RFID is high because of its expensive reader. Overall, the choice of which beacon technology to use depends on the specific application and requirements of the user.
Which Applications Are More Suitable for NFC Beacons?
Based on the advantages and limitations of NFC beacons, here are some applications where NFC beacons are more suitable:
Access Control: NFC beacons are well suited for use in secure access control systems, such as employee attendance tracking or facility access control because they enable wireless communication between two devices in close proximity. By using an NFC-enabled device, employees can quickly and easily access secure areas by simply tapping their device on the beacon.
Loyalty Programs: NFC beacons can be used for loyalty programs, allowing retailers to offer rewards or discounts to customers who check in using their NFC-enabled devices. This suits companies looking to foster engagement and brand loyalty by building brand-consumer relationships.
Information Retrieval: NFC beacons can be used to provide information to customers or employees, such as about museum exhibits or product information in a retail store.
Payment Processing: Due to their short range and secure communication protocol, NFC beacons are well-suited for contactless payment processing, allowing customers to make payments using their NFC-enabled devices.
One case study is transportation. For travelers, NFC gives mobile phones a big advantage over paper tickets. Tourists only need to click on the information TAB embedded in the smart poster to download relevant data, such as train schedules and information about nearby attractions, which reduces many troubles during the journey. Mobile asset tracking devices allow operators to provide extra services, including language selection, direct marketing, opportunities for advertising and promotions, trip information, and loyalty programs.
With the proper implementation of NFC technology, we see incremental growth. Various industries need to go contactless to ease operations. By being more nimble and optimizing their solutions with technologies like NFC to support the present value chain, businesses can get an advantage over their rivals.
Which Applications Are More Suitable for Bluetooth Beacons?
Based on the advantages and limitations of Bluetooth beacons, here are some applications where Bluetooth beacons are more suitable:

Beacons have a longer range than NFC, which makes them better suited for location-based applications. Thus, Bluetooth beacons are well suited for indoor navigation, providing turning directions within a building or facility, which is particularly useful for large retail stores or airports.
Proximity Marketing: Within a specified range, devices can detect the unique identifier that Bluetooth beacons transmit and use that information to trigger particular actions. So beacons are ideal for location-based proximity marketing and advertising, where promotional messages or coupons are sent to customers who are close to the beacons.
Asset Tracking: Bluetooth beacons can be used for asset tracking, allowing businesses to track the location of valuable assets within a facility or warehouse.
Real-Time Location Services: Bluetooth beacons can be used for real-time location services, allowing businesses to track the location of employees or customers within a building or facility.
In conclusion, both NFC and Bluetooth beacons offer unique advantages and can be used for a wide variety of applications. When choosing between NFC and Bluetooth beacons, it’s important to consider factors such as range, data transfer speed, battery life, compatibility with devices, cost, and security.
