There used to be SD cards with built-in WiFi which could sync photos automatically, but the main player in that space (Eye-Fi) went out of business and I don't think anyone else has stepped up to make a version of that which works with modern cloud services. Not enough demand now that smartphones have obliterated the consumer camera market, I guess.
