The wise S2 card has a USB I/F for computer connection and every NVS has USB host I/F for USB memory card or card reader.
But there were USB compatibility issue with Wise S2 card for 32GB(or less) Wise S2 card with NVS.
This compatibility issue cleared from 64GB Wise S2 card, so you can connect Wise S2 card to USB host port of NVS to copy the Wise S2 card directly.
For NVS2500 & NVS2501, you can plug in the Wise S2 card to the SxS slot and copy it. But this does not supported by NVS2525.
