"banking, railways, shopping carts, electricity, telephone departments etc are few in them "

I can't understand the meaning of the sentence "are few in them", doesn't it mean that computers are being used more and more in these industries?

The sentence is badly written and ungrammatical. The phrase "are few in them" has no meaning. The writer possibly wanted to say "are a few of them", but that is pure conjecture on my part because I am not a mind-reader.
