Did not know that a digital pick system in the end is what product, although also heard that in front of me many friends that a product is so awesome, but I never used, so do not know the specific functions of how strong, as before a period of time I have access to the Internet for information on this, see this in a digital pick system special for our company, so the first time to go to the company to which we booked digital pick system, was also estimated to have a few days to think you can install and use, but did not expect professional the company is professional, the work efficiency is terrific. Second days for us directly installed.
