microSD / TF: use a compatible microSD slot or a suitable SD adapter; an adapter changes size, not card-standard support. xD-Picture Card: found in some older Olympus and Fujifilm cameras, and needs an xD-compatible reader. CompactFlash (CF): needs its own matching slot—never force the card onto the pins.

Only if your exact camera supports wireless photo transfer and has a compatible manufacturer app. Check its instructions rather than assuming Wi-Fi or Bluetooth from the brand. For cameras without wireless transfer, use a matching card reader or supported USB data cable.

A card reader only reads the card you put into it, not photos stored inside the camera. Some cameras use built-in memory instead: the Nikon COOLPIX S01 cannot use memory cards at all. Nikon’s S01 reference manual describes copying pictures to a computer over USB. Its original software instructions are from the camera’s release era, so check current operating-system support before installing anything. For another model, check its own internal-memory transfer instructions rather than buying a reader first.

First check that the reader supports both your card and your device. In Photos, look for Import or the connected camera/card under Devices; the location varies by iOS version. With a direct camera connection, make sure the camera is on and in the correct transfer mode. If no transfer is running, disconnect the adapter, wait 30 seconds and reconnect it. Apple’s camera-adapter troubleshooting guide also recommends trying another device or computer if importing still fails. Its advice does not establish compatibility for every third-party reader.

Apple notes that an unsupported media format may not display on the iPhone or iPad, and camera-adapter importing may not accept files that were renamed, edited or copied onto a card. Try copying the originals to a compatible computer before changing anything on the card. A file missing from the import screen is not, by itself, proof that the photo has been deleted.

Let the transfer finish, open several copied photos and videos, and make a separate backup before deleting originals. Choose Keep rather than Delete if an import app asks and you have not verified the copies. Do not disconnect a camera while it is transferring. If a card reader appears as a removable drive, eject it before unplugging.
