This is the reason why Isielog designs “custom-made” Cabinets & Racks, based on each terminal put into production, compact, with mobile option (with or w/o wheel), which could accommodate any quantities of terminals.
These “Racks” or "Storage Cabinets" are electrically wired which allows the terminals to be charged on their support and / or integrate battery chargers supports in addition.
These cabinets could be connected with network cable and connected to internal server (especially for remote control and updates for terminals) as long as they are plugged into the cradles.
