RFID vs. QR Code: what's the difference? Which one is better for your business?

Both RFID (Radio Frequency Identification) and QR Codes are technologies used for asset tracking and inventory management. These technologies are applied in many industries such as retail, construction, energy, maintenance, healthcare, laundry, PPE, etc.

Understanding your needs in term of cost, durability and security can help you to evaluate the best option for your business. In this article, we will define RFID technology and discuss the differences between the two technologies.

What is RFID?

RFID means Radio Frequency Identification, which uses radio waves to transmit information from RFID tags to an RFID reader.

Basically, an RFID solution is composed of an RFID tag, an RFID reader, and an IT framework to collect and manage the data.

RFID's main function is to ensure the correct identification and tracking of products and goods with which they are equipped.

What is a QR Code?

A QR Code is a one- or two-dimensional representation of numeric or alphanumeric data in the form of a symbol consisting of black bars or square modules and spaces. The QR Code is used to identify goods in retail, warehouses, factories etc. It allows the correct identification and tracking of products and goods.

What is the difference between RFID and QR Code?

In fact, there are many differences between RFID and QR codes.

- QR Codes can only be read one at a time, unlike RFID, which can identify multiple tags with a single reader.

- QR Codes require eye contact, whereas RFID is a technology that allows the scanner to read tags even when they are invisible or embedded in certain materials.

- QR Codes are sensitive to deterioration that can affect their readability. In contrast, RFID tags are more robust, able to withstand more wear and tear.

- QR codes, unlike RFID, is limited by the type and volume of data that can be stored.

RFID or QR code, which is better?

Today, QR code technology is relatively more mature, costing less than RFID, and has been used in the market for a long time with a perfect standard system, which has penetrated our daily life and work. However, in the long run, RFID start to be used by more and more industries due to its many advantages. With the continuous development of information technology and the gradual reduction of RFID costs, the future of RFID is bright.
