RFID technology (Radio-frequency identification) vs NFC (Near Field Communication) are increasingly being widely applied in various industries and have become important factors in optimizing business processes. The article below will help you understand better RFID vs NFCthe differences as well as discover the right application and choice for your business.
What is RFID Vs NFC?
What is RFID?
Radio-frequency identification (RFID) is a wireless communication technology that helps identify, track and manage objects through radio waves. RFID systems include readers, tags, and software to control operations as well as store data if necessary.
The reader sends a signal to the tag, and the tag transmits ID information to the reader. The data can then be transmitted to a database for storage or analysis.
What is NFC?
Near Field Communication (NFC) evolved from RFID and can be considered a subset of it. Unlike RFID, NFC uses a magnetic field transmitter instead of a radio transmitter. System NFC also includes the same components as RFID, including readers, tags, and software.
Compare RFID Vs NFC
| Characteristic | RFID | NFC |
|---|---|---|
| Alike | Uses radio waves to exchange information with card reader devices. | Uses radio waves to exchange information with card reader devices. |
| Different | ||
| Reading Range | 3 – 6 meters, no tag in sight. | Short, about 1 – 10cm, the tag should be within sight. |
| Communication Type | One-way communication, no response from card. | Two-way communication, can exchange information. |
| Data Transfer Speed | Faster transmission speed, can scan multiple cards at the same time. | Transmission speed is slow, not exceeding 424 kbit/s. |
| Datatypes | Save ID information. | Save multiple data fields, suitable for payments. |

Application of RFID technology
Access control: Used in security to manage access to computers and restricted areas.
Real-time control system: Track the location of employees, customers, and goods in real time.
Logistics and supply chain: Used to track and control vehicles and moving goods.
Inventory management: Easily manage inventory and track assets across multiple points of sale.
Animal tracking: Used in animal tracking solutions.
Marketing: Use in advertising posters, smart items, mobile applications, etc
Application of NFC technology
Contactless payment: Safe for short range contactless payments.
Data exchange: Allows data exchange between two devices.
Access control: Use in accessing vehicles or restricted areas.
Health care: Monitor patient status and records, check schedules, and access necessary equipment.
Smart ticketing: Use NFC to grant access to public transportation, concerts, movies, and more
How to choose RFID vs NFC
Reading distance:
Depending on the frequency and power of the machine, RFID may have a larger read range.
NFC operates at 13.56 MHz with a shorter range.
Tagged object content and components:
Liquids and metallic materials can affect the readability of the card.
The environment affects the card, some require an environmentally resistant cover.
Card shape and size:
RFID tags come in many different shapes and sizes.
Environmental conditions:
Determine the working environment to choose a card with a cover suitable for environmental conditions. The card is sensitive to environmental conditions such as humidity, temperature, vibration, and chemical agents.
Memory storage:
Card capacity depends on information storage needs.
Technology RFID vs NFC not only brings convenience but is also an important tool to help businesses optimize production and business processes. Through this article, you will have an overview of features, applications, and how to choose the right technology for the specific needs and current status of your business.
