Blindingly fast data entry

This man punching numbers into the device hanging from his belt with a calm ferocity is doing inventory. A commenter on Reddit explains:

He is doing an inventory audit on the store. First, he enters the price, then the number of items, then moves to the next item. The entering of items is done by doing them in groups. When I used to do this, I would count in 4s. It would be 4+4+4+4+4+3 to indicate 23 items. When he looks at the 10-key he is probably correcting an error he just made. It is pretty rare to double check the count unless you fat fingered something. The end report does not contain SKU numbers but a categorical pricing of all the items in the store.

In Japan, there are competitions and clubs for performing quickly on calculators. Asuka Kamimura, a young Japanese featured in the beginning of this video, can work her calculator at a rate of nine keystrokes per second.
