What is the difference between NFC and Bluetooth in application?

NFC and Bluetooth do not compete, but complement each other. Although bluetooth pairing has been well established and The Android and Apple iOS standards have been unified, it may still take tens of seconds to successfully pair up due to the different bluetooth functions in different phones or devices.

NFC, on the other hand, can instantly match a phone with another device or provide real-time configuration or connection (such as a website, router, wifi) with a simple touch, and Michael WAI, the manager, said that in the future, NFC may become the default mode, turning off only in airplane mode to improve the user experience.

NFC can also be in need of user cognition and approval, provide a reliable and trusted interaction, the action of touch is actually used to help the user to provide an authorization to execute the command, such as payment, open the door, permission to exchange information... The act or process of, etc. Even bluetooth can do this, but the lack of user confirmation, especially in security-related and payment applications, can raise security concerns.

In short, if the need for fast, user confirmation, data transmission volume is small, NFC is a good choice; When long distances (50cm to 100cm) are required, data transfer is frequent, and user engagement in information exchange is low, Bluetooth becomes an inevitable choice.

No matter what technology is used, the biggest challenge is often to think about how to improve user experience and bring real convenience to users. If users change their habits to accommodate a certain technology, there will be some obstacles; On the contrary, if technology can bring more convenient and better user experience, it will be twice the result with half the effort. No matter NFC, Bluetooth, Internet of Things or access control technology is the ultimate goal.
