Besides retail, the hospitality industry also makes use of cash registers and POS systems. Depending on where the system is used, they usually work differently from those in retail. For example, a restaurant cash register has to store information about every order, such as who ordered what from each table, whether the bill should be split or not, and whether a tip is added. Another example is in hotels, where a cash register has to store information about every room, such as who has booked the room, for how long, and what extra services are needed.
