Generally there are dozens or hundreds of bytes of non-volatile storage space available for reading and writing, and now the newer dogs also include a single-chip microcomputer. Software developers can use the interface function to exchange data with the dongle (that is, read and write the dongle) to check whether the dongle is plugged into the interface; or directly use the tools attached to the dongle to encrypt their own EXE files (commonly known as "packaging").

In this way, software developers can set up multiple software locks in the software and use the dongle as a key to open these locks; if the dongle is not inserted or the dongle does not correspond, the software will not execute normally.
