U Disk Requirements:
1. Format should be FAT32
2. The capacity should not be over 16G; support USB 1.1 and some USB 2.0 (USB 3.0 is not supported).
3. GHOST file should not exist in U disk. So it is suggested that format the USB flash drive first.

3) INFO.XLS (Punch schedule and shift schedule)
4) AFP.DAT (This file includes user information and fingerprint image. You can directly copy and upload this file to the same machine. Users can swipe fingerprints on other machines without registering each machine one by one.)
