How do RFID tags work?
RFID tags contains a microscopic chip that emits radio signals. When attached to the product, each tag has a unique code. RFID reader, with receiving antenna, is capable of receiving waves from tags within a range of 0.5 to 30m. After being collected, data is transmitted to the server system/warehouse management software.
What are RFID tags used for?
In addition to warehouse management, RFID tags are also used in cars, computer equipment, and even animals during transportation.
What is QR Code?
QR code was developed in 1994 to improve inventory management systems. Like barcodes, QR codes can be read horizontally and vertically, increasing speed and data capacity, as well as improving error resistance.
How do QR codes work?
QR codes is square in shape with separator markings at 3 of the 4 corners, allowing it to be read quickly from any angle. QR codes are commonly used in inventory management and online payments.
Compare RFID vs QR Code applications in warehouse management

- Both can be read by different devices.
- Information on both can be read and processed.
Differences between RFID vs QR code:
| Compare | RFID | QR Code |
| Reading method | Radio | Optical scanner |
| Line of sight | No need | Need |
| Scanning device | Specialized equipment | iPhone, handheld device |
| Reading distance | Read distance (0.5 – 30m) | Close reading (1m) |
| Readability in obscured barcode conditions | Can read all barcodes in coverage area including obscured ones | All barcodes can only be read within the reader device's line of sight. |
| Reading speed | Fast, read multiple cards at once | Only 1 code can be read at a time |
| Accuracy | Poor when passing through metals or liquids | High |
| Investment costs | High due to the need for cards and specialized equipment | Cheaper (reader and printer) |
| Import/export warehouse | Read automatically when products pass through the warehouse door | Scan each code when needing to import/export inventory |
| Warehouse inventory | Save 50% inventory time compared to traditional methods | Scan each code |
How to choose the right RFID Vs QR Code
Choose between RFID vs QR code depends on the specific characteristics and requirements of the business. RFID is suitable for automatic warehouse import/export processes and quick inventory, while QR code is suitable for businesses with low investment budgets and warehouse import/export requirements are not too complicated.
