qazThere are SD cards with WiFi support
Yup. It was used to transfer photos from a camera to a phone back in the day when cameras didn’t have wireless transfer features.
They’ve been around for a while. I used one with a 5D MkII several years ago. Horrible throughput. It was only useful for a quick transfer of a few images. Totally unsuitable for field dumps.
Had one for my iPaq.
