RFID vs. BLE: Capabilities and Comparison of Asset Tracking Technologies

RFID (Radio Frequency Identification) and BLE (Bluetooth Low Energy) are two distinct wireless communication technologies that are used for various applications. RFID is a passive technology that uses radio waves to transmit data between the reader and the tag. The tag is attached to an object and contains a unique identifier that can be read by the reader. BLE, on the other hand, is an active technology that uses low energy Bluetooth to transmit data between devices. BLE is commonly used in wearable devices and smart home devices.

This blog post will help you to learn about the uses of RFID and BLE technology including RFID asset tracking and Bluetooth tracking, RFID vs. BLE key differences and determine which technology is best suited for specific requirements.

Uses of RFID Technology

Inventory Management

RFID technology can be used to track assets and manage inventory in real-time. RFID tags are attached to assets and read by RFID readers to accurately track the location and status of assets in the labs, data centers, manufacturing facilities or warehouses. This enables businesses to have a better understanding of their inventory and avoid stock shortages or excess inventory.

Supply Chain Management

You can use RFID technology to track and manage raw materials and finished goods throughout the entire supply chain, from production to delivery. RFID tracking helps to track work orders and WIP at every stage of the manufacturing process and enables to track the movement of raw materials and products throughout the supply chain. This helps companies to streamline their supply chain process, identify and fix any bottlenecks and improve the overall efficiency and outcome.

Asset Tracking

RFID asset tracking can come in handy to track a wide range of assets including lab equipment, IT assets and tools. It helps businesses to quickly locate the assets for use, calibration and preventive maintenance. RFID helps businesses to complete inventory audits 10x faster, improve asset utilization and improve efficiency. 

Lab Sample/Specimen Tracking

In addition to tracking lab equipment, RFID can also be used in tracking lab samples/specimens that are used in various clinical trials and tests. It helps to get visibility of lab samples through various stages of testing, eliminate diagnostic errors through accurate lab sample tracking, get real-time inventory and improve lab testing process.

Uses of BLE Technology


BLE technology is used in wearable devices, such as smartwatches, fitness trackers, and smart glasses. BLE devices can be paired with smartphones or other devices to transmit data, such as fitness and health data, in real-time. This allows individuals to monitor their health and fitness levels and make more informed decisions about their lifestyle.

Smart Home Devices

BLE technology can be used in smart home devices, such as lighting systems, security systems, and smart thermostats. BLE devices when paired with smartphones or other devices are used to control and monitor the functionality of smart home devices from anywhere, at any time.

In-Store Navigation

BLE technology can be used in in-store navigation to help retailers to improve the shopping experience and increase sales. It helps customers find products and navigate the store. BLE beacons can be placed throughout the store and paired with a customer’s smartphone to provide real-time information and promotions based on their location in the store.


BLE technology enables healthcare providers to monitor their patients’ health and wellness, and make more informed decisions about their care. BLE devices, such as wearable health monitors, can be paired with smartphones or other devices to transmit health data, such as heart rate and sleep patterns, in real-time.

Industrial IoT

BLE technology helps businesses to increase the efficiency of their operations and reduce the risk of equipment failure. Bluetooth device tracking can be used in the Industrial Internet of Things (IIoT) to monitor and control industrial devices and systems. BLE devices can be paired with smartphones or other devices to monitor and control the functionality of industrial systems, such as production line machinery and HVAC systems.

Asset Tracking

BLE Technology can also be used for asset tracking purposes, as an alternate to RFID asset tracking. Bluetooth tracking is typically used when assets are needed to be tracked in large open areas like open factory floors that may be more than 25,000 sqft in size or in large open yards, which might span several acres.

Comparison of RFID vs. BLE


Since RFID tags don’t have a power source, they rely on RFID scanners to power them. The read distance of the average RFID tag is typically shorter than the read distance of the average BLE tag. There might be variances in specialized RFID and BLE tags, where the RFID tags may be readable at longer distances than Bluetooth tags.

Data Storage

RFID tags have a limited amount of data storage compared to BLE devices. RFID tags typically have a storage capacity of up to several kilobytes, while BLE devices can have storage capacities of up to several megabytes. Because of this, BLE is a better choice for applications such as wearables that require additional data storage.

Power Consumption

Since RFID tags have no power source, they rely on an RFID scanner in close proximity to power them. Batteries power Bluetooth tags and hence have their own power source. Therefore, for applications that require the tag to be working continuously, like in wearable technology, BLE is the better option when compared to RFID.


Both RFID and BLE technology have varying levels of security, depending on the implementation. RFID tags can be encrypted to prevent unauthorized access to the data, while BLE devices can use secure communication protocols to protect against hacking.


RFID and BLE technology can be designed to work with a wide range of other devices, depending on the implementation. RFID readers can be designed to work with multiple types of RFID tags, while BLE devices can be designed to work with other BLE devices and other Bluetooth-enabled devices.


The cost of RFID and BLE technology can vary greatly depending on the implementation and the specific requirements of the application. RFID tags are typically less expensive compared to BLE devices, but BLE devices offer more advanced features and functionality.

RFID vs. BLE: How to Choose the Right Technology

RFID and BLE technology each have their own strengths and weaknesses, and it’s important to understand the trade-offs between the two technologies. When choosing between RFID and BLE technology, it is important to consider the specific requirements of your application. Factors such as read range, data transmission speed, and cost should be taken into account to determine which technology is best suited for your needs.

The cost of RFID and BLE technology can vary greatly depending on the specific requirements of your application. It’s important to conduct a cost vs. benefit analysis to determine the total cost of ownership of each technology and determine which technology is the most cost-effective for your needs.

In conclusion, both technologies have a wide range of applications, from lab equipment tracking, inventory management, tool tracking, lab sample tracking, WIP tracking, and supply chain management to wearables, Bluetooth device tracking and smart home devices. Ultimately, the choice between RFID and BLE technology will come down to a trade-off between cost, performance, and application requirements.
