How to find, although digital technologies are all the time developed, on many trains, machines and other bulky equipment, long-dead floppy disks are still used.

Of course, it is possible to carry out modernization, but it is costly and far from always profitable. For example, according to Aeroweb in 2020, there were 7,690 aircraft that received money transfers. Often routine, with a minimum margin, then no investment in new technologies, etc. Especially if the floppy disks are successfully vypolyot
