Yes, the tax is paid by the consumers. But, those consumers will probably not be willing to pay more just because the company was too slow in updating their cash registers. So the problem quickly solves itself.

I don’t see the problem. Drop the tax and if the companies can’t handle it, they continue to pay it. And once it costs them money they will fix it in 1 week instead of a year.

Perhaps also an off-site backup ;-)

The G-Drive couldn’t have a backup system due to its large capacity

Peak competence there.
