Do-it-Yourself Credit Card Processing

In an effort to speed up table turnover at peak hours and eliminate waitress credit card skimming (waitresses who take your credit card as payment and make a copy of the information for themselves or to sell), many US restaurants are installing swipe machines at each table at sit-down restaurants.
This do-it-yourself credit card processing is common at gas pumps and many retail shopping establishments in the US, but has barely even started in sit-down restaurants.  Mostly due to restaurant owners not wanting to pay to get the equipment.
Participating restaurants will have remote-control like units on each table that allows people to swipe their credit or debit cards at their tables and pay for both the food and a tip.  The card information is sent wirelessly to the restaurants computer and a printer will spit out the receipt that a server will bring to the table.
If this becomes popular in the US restaurants, I think they should take it a step further and have the hand held device act as both the menu and the order taker, as well.  Let me enter my order in the remote-control, and have the printer in the kitchen spit it out for the cooks.  That ought to speed up the process of waiting for the server to make it over to take our orders, too.
