As we may think response

"Even such devices are much too slow when it comes, for example, to matching a set of fingerprints with one of five million on file. Selection devices of this sort will soon be speeded up from their present rate of reviewing data at a few hundred a minute. By the use of photocells and microfilm they will survey items at the rate of a thousand a second, and will print out duplicates of those selected."

This is an interesting thought. I'm not too sure how fast fingerprints can be found in the police database now a days but it just shows how far technology was expected and how far it has gone.
