Data Transfer
Once connected and cards are inserted, your device should recognize the card reader as an external storage device. You can then drag and drop files, copy, or move data as you would with any other storage medium.
Data transfer speeds can reach up to 5Gbps, allowing for quick transfer of large files like high-resolution videos.
