NFC vs. Wi-Fi Direct: Comparing File Transfer Methods for Android to PC


“Could you advise on the feasibility of using an NFC reader connected to a PC for file transfers from an Android device? Would this method be more efficient than wireless transfer applications like Samsung Flow, considering my PC lacks Bluetooth capability? Additionally, what requirements must be met for such a setup to function effectively?”


In the modern era of technology, the quest for efficient file transfer methods between devices is ever-evolving. Near Field Communication (NFC) stands out as a potential solution for transferring files from an Android device to a PC. This article delves into the feasibility, efficiency, and requirements of using an NFC reader for such purposes.

NFC is a form of wireless data transfer that allows two devices to share information when they are in close proximity. It operates at a frequency of 13.56 MHz and can transfer data at speeds up to 424 Kbits/second. NFC is commonly used for contactless payments and quick data exchanges between smartphones.

NFC vs. Wireless Transfer Applications

When comparing NFC to wireless transfer applications like Samsung Flow, which uses Wi-Fi Direct, NFC is generally more straightforward to use but offers slower data transfer rates. Samsung Flow and similar applications facilitate file transfers over Wi-Fi, boasting higher speeds and the ability to handle larger files more efficiently. However, NFC’s simplicity—requiring just a tap to initiate the transfer—can be appealing for small, routine data exchanges.

Feasibility and Efficiency

The feasibility of using an NFC reader connected to a PC hinges on the nature of the files being transferred. For small documents or images, NFC can be a quick and convenient method, especially if the PC lacks Bluetooth capability. However, for larger files or frequent transfers, the efficiency of NFC may not match that of wireless applications due to its slower transfer rate.

Requirements for Setup

To set up an NFC reader for file transfers, the following requirements must be met:

  • Both the PC and the Android device must support NFC.
  • An NFC reader, such as the ACR122U, must be connected to the PC.
  • The Android device should have NFC enabled and be capable of initiating the transfer.
  • Software or applications that facilitate NFC communication between the PC and the Android device must be installed.


In conclusion, while NFC readers can be used for file transfers from an Android device to a PC, their efficiency compared to wireless transfer applications is limited by slower data transfer rates. The setup is feasible for small-scale transfers and situations where other wireless options are unavailable. However, for larger files or more frequent transfers, applications like Samsung Flow may be more suitable due to their higher speed and efficiency. The choice ultimately depends on the specific needs and constraints of the user.
