I have purchased some Samsung Slate Tablets for my users. We currently use True crypt for encryption. It asks for a password upon booting into windows. Currently the only way to input the password is with a usb keyboard since Bluetooth does not seem to be active yet. Is there a way around this that i can let my users use a Bluetooth keyboard to log in or are they stuck with a bigger usb keyboard to get past the encryption? They are currently running Windows 7.
