  2. Due to reasons, I questioned why we still need to load software via USB, a method that harkens back to the early '90s. Surely, there's a better way. This led me to consider the potential benefits of integrating NFC (Near Field Communication) technology directly into the ESP32 microcontroller. NFC could revolutionize how we interact with these devices, particularly during the initial setup and configuration stages.
  3.  
  4. Proposal: Integrate an NFC tag into the ESP32 boards to allow for wireless, contactless setup and configuration. This feature could enable developers and users to load initial firmware, set network configurations, or even update device settings with just a tap from an NFC-enabled device.
  5.  
  6. Advantages:
  7.  
  8. Simplified Setup: Streamlines the configuration process, making it more accessible to all user levels.
  9.  
  10. Reduced Hardware Dependencies: Eliminates the need for USB ports on the device, reducing costs and potential failure points.
  11.  
  12. Enhanced Security: Offers secure data transfer through encryption, suitable for sensitive information like Wi-Fi credentials.
  13.  
  14. Scalable Configuration: Facilitates rapid, uniform setup across multiple devices, ideal for large-scale deployments.
  15.  
  16.  
  17. I believe this update would not only keep the ESP32 competitive but also expand its use in educational, commercial, and DIY projects, aligning with modern technological trends. I am keen to hear the community's thoughts on this proposal and discuss its feasibility with Espressif's engineering team

Thing is, technically this already is possible by integrating an external NFC chip (like the ubiquitous RC522) on a board. The fact that there's a ton of ESP32-based boards out there but very few of them have a chip like that as a feature makes me think that there's not really that much demand for it.

I can float it by some colleagues, perhaps there's some interest in doing this, but don't hold your breath.
