Yes, for full-size SD cards. The OntheGo 5-in-1 Multiport Adapter adds a full-size SD card reader (UHS-I, up to 104MB/s) to your MacBook Neo. Insert the SD card with the pins facing down. The OntheGo 5-in-1 does not have a dedicated microSD slot, so to use a microSD card you would need a microSD-to-SD adapter.
