Description

technical field [0001] The invention relates to the technical field of settlement systems, in particular to a settlement system based on the Internet of Things. Background technique [0002] At present, in the canteens of enterprises and institutions such as colleges and universities, large companies and factories, there are often long queues of people waiting for meal selection and credit card settlement during the peak dining period. At present, the meals in the canteen are basically randomly placed in different areas, and the diners have to shuttle between different areas in order to get the desired dishes, which causes congestion and wastes time. In addition, the current cost calculation method mainly relies on manual work. One employee and one computing terminal are basically manually visually inspecting the dishes on the plate and adding up the prices one by one. When there are many varieties, the error rate is high, especially when the prices of dishes in restaurants...

AI Technical Summary

Problems solved by technology

At present, the traditional credit card system in canteens usually has the following disadvantages: when paying for meals, employees need to identify the type of food and enter the price of the food before swiping the card for settlement. Manual billing errors are unavoidable and occur from time to time; , time-consuming and inefficient

Its shortcoming is that the settlement system adopts the method of RFID electronic tag identification to realize fully automated settlement, but the plates used must be customized, and the cost is relatively high

Through this implementation method, the serving speed and settlement efficiency are improved, and the passenger flow is increased. However, this solution still has shortcomings. This solution cannot adapt to the fast-food catering industry, and the processing of information cannot achieve real-time and rapid changes.
