No.

I said 1 mA, but it can be much less.

The basic idea is that you have an array of horizontal wires and
vertical wires, that do not touch. Each crossing is one key. When a key
is pressed, the two wires touch. You get a little current or voltage
variation in one vertical and one horizontal wire of the bunch.

The position is used to codify a number that is sent via some type of
serial bus.

That's the basic idea, details have changed over the eons. :-p

The time depends on the human. And also because the array can be scanned
by pulses.

Right. :-)

And then there is the awful noise from the cpu, ram, buses... :-)
