Self-service POS Kiosk

Some service industries face a lack of manpower. Other businesses try to provide enhanced 24hr services for their customers, but face staff shortages to do shift work. One possible solution is to deploy self-service POS Kiosk. For example, a café can implement of POS Kiosk where a customer can place his own food order and complete payment by himself. Such order will then be electronically sent to the kitchen for preparation. This setup will allow the café to do with less waiter/waitress to take customer orders and have time to serve food to more customers.
This self-service POS Kiosk idea has also been implemented in supermarkets.
