Applications moved to memory card are encrypted and use ASEC file extension. ASEC files can be found in .android_secure folder saved on memory card.
Applications stored in ASEC encrypted file format cannot be modified by other applications installed in phone, or computer. Applications installed on SD card are paired with Android phone, where they have been installed. It is not possible to put SD card to other Android phone and run applications installed on SD card.
