You can access the data on the microSD card without needing an external card reader. This is explained in the following steps:
Turn Extender ON. The Status LED will turn green.
Ensure no headsets are connected to Extender.
Plug Extender into a PC, your computer should detect it as a generic USB drive and after a few moments you should see it appear as a drive. You can now access the encrypted files on the disk.
Note: All data stored to the SD card is encrypted and the EMOTIV App and a PRO license is required to decrypt the raw data.
