Description

1241780 V. Description of the invention α) [Technical field to which the invention belongs] The present invention relates to a portable wireless electronic device, and more particularly to a wireless electronic menu device. [Previous technology] The current wireless electronic ordering machines are constructed by personal digital assistants (PDAs) or desktop computers and radio network systems. The main focus is to shorten the waiter and chef, storage The time for information transmission between counters is “but”, but there are some shortcomings. For example, the operation interface of a personal digital assistant or desktop computer is too complicated and the price is too expensive. Therefore, the current wireless electronic ordering machine is operated by the waiter, not by the customer himself, and cannot meet the requirements of lower waiter labor costs; 2 · The interaction between the waiter and the customer and the traditional There is no difference in methods and no progress; customers still browse the traditional paper-style menus and ask the waiters about today's special meals, special offers, etc., causing customers to often be unable to understand and choose the meal items they want; 3. The cooking instructions for the meal items, such as the cooking process, method, calories, taste, etc., need to be answered by the waiter, but the answers are often different or unclear; 4. Customers often cannot See the total consumption amount or all meal items and total calorie information in advance; 5. During the meal, if the customer needs immediate service, such as tableware, paper towels, condiments, free drinks ... etc., because it is generally personal Digital assistants are not at the customer's side, which often causes them to be unable to meet demand in a timely manner and has to wait for the arrival of the waiter. Therefore, the present invention provides a wireless electronic menu device to solve the above problems.
