Stopping payments in cash?

There was an article on the newspaper today about one restaurant in Tokyo stopping payments in cash, accepting only electronic money or credit card. Apparently, it's a system that allows all payment to be done at the table. According to the article, fewer workers are needed by doing so.

Maybe we can stop depositing money into bank accounts? Will that lead to lower labor cost? It probably won't make much of a difference.
