RFID and QR Codes: What are the Similarities and Differences?
Both RFID and QR codes utilize contactless methods for data transmission and collection, enhancing interaction and elevating the customer experience. However, these two technologies differ in their reading methods, reading ranges, and reading speeds. In this article, IT Nam Viet will provide a detailed comparison of the similarities and differences between RFID and QR code technologies. Don’t miss out!
Rfid and Qr Code
What is RFID? An Overview of RFID Technology
RFID stands for Radio Frequency Identification. It’s a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system comprises:
An RFID system uses RFID tags attached to the objects that need to be identified. A two-way radio transceiver, called an interrogator (in this case, the RFID reader), sends a signal to the RFID tag and reads the data returned from it.
RFID is utilized in a wide range of everyday applications, with some prominent examples including: RFID in library management, RFID in logistics, RFID in asset management, RFID in warehouse management, RFID in animal tracking, RFID for bus systems, and RFID in healthcare.

What is a QR Code? An Overview of QR Code Technology
QR Code, short for Quick Response Code, is also known as a matrix barcode or a 2D barcode. It is a type of encoded information displayed in a way that machines can read. QR Codes first appeared in 1994, created by Denso Wave (a subsidiary of Toyota). A QR code can hold up to 7,089 numeric characters or 4,296 alphanumeric characters, including punctuation marks and special characters.
QR Code applications
QR Codes allow for quick scanning and decoding with devices like barcode scanners or camera-equipped phones with QR code scanning apps, offering great convenience to users. QR Code technology can encode a variety of information, including text, URLs, Wi-Fi network details, and more. It can even encode entire sentences and phrases.
QR code solutions are widely used in various aspects of life, with notable examples including advertising, marketing, product packaging, event ticketing, restaurant menus, and more. QR codes enable users to access content quickly, enhancing their experience and increasing engagement.
Similarities Between RFID and QR Code Technologies
Both RFID and QR codes can store and transmit information digitally, allowing for larger data capacity compared to traditional technologies. Moreover, both technologies utilize contactless methods for data transmission and collection:
QR codes: Users simply scan the code with a camera.
RFID: Radio waves are used to capture data.
Furthermore, another significant similarity between these two technologies is their machine-readability, enabling automation of data scanning and processing, which optimizes time and cost efficiency. In addition, implementing RFID and QR codes offers the advantage of increased interaction and enhanced customer experience, while minimizing errors in management and operational processes.
For example, you can scan a QR code to access detailed product information, while RFID can be used for contactless payments, providing a convenient shopping experience.
In conclusion, both RFID and QR code technologies offer practical benefits to businesses in information management and process automation, effectively contributing to improved and enhanced customer experiences.
Differentiating Between RFID and QR Codes
Despite sharing some similarities, these two technologies have distinct differences, as highlighted in the following comparison table:
Feature
RFID
QR Code
Reading Method
Uses electromagnetic fields to automatically identify and track tags attached to objects
Uses optical scanners, often integrated into cameras
Line of Sight
DOES NOT require a direct line of sight
REQUIRES a direct line of sight (though easier to aim than traditional barcodes)
Reading Device
Requires specialized RFID readers
Can be read with smartphones equipped with camera-based QR code scanners or dedicated QR code readers
Reading Range
Can read from a distance (0.5 – 30m), enabling contactless and automated data collection
Can only be read at close range (under 1m)
Reading Conditions
Can read all tags within the radio wave range, even if obstructed
Can only read codes within the direct line of sight of the device
Reading Speed
Can read multiple tags simultaneously at high speed; however, signal transmission through metal or liquid environments can be significantly reduced
Can only read one code at a time
Security and Privacy
Higher security due to data encryption and protection through access control methods; reader collision can occur when two signals overlap in close proximity; if one device in the system fails, RFID may not function
Can be easily duplicated or tampered with; however, encryption and secure QR code generation methods can enhance security
Investment Cost
Higher cost due to the need for specialized equipment to operate the RFID system
Lower investment cost (code readers and QR code printers)
Warehouse Inbound/Outbound Process
Reader reads all tags attached to products, even if they are not visible. Data is transferred directly to the server to compare and verify inbound/outbound quantities and generate new receipts.
Uses devices integrated with warehouse management software to scan codes on cartons/pallets. Information is connected to the software system to automatically generate goods issue/receipt slips.
Inventory Management
Fast, time-saving, and labor-saving due to accurate reading capabilities for large quantities
Inventory takes more time compared to using RFID technology for warehouse management.
FAQs – Frequently Asked Questions about RFID and QR Codes
We regularly receive inquiries about RFID solutions and related technologies, including QR codes, across IT Nam Viet’s online platforms. In the following section, we address some common customer questions about RFID and QR codes:
Can RFID readers scan QR codes?
The answer is NO. RFID readers use radio waves to communicate with RFID tags equipped with chips and antennas. In contrast, QR codes are essentially 2D barcodes that can be scanned and decoded using smartphone cameras or dedicated QR code scanners.
