Method and device for assisting self-service settlement machine in preventing order escape

Abstract

The embodiment of the invention provides a method for assisting a self-service settlement machine in preventing order escape. The method comprises the following steps: obtaining the weight of each commodity; obtaining the actual total weight of all the to-be-settled commodities which do not enter the settlement process through overall weighing; respectively obtaining the weight of each to-be-settled commodity in the settlement process, so as to calculate and obtain the actual total settlement weight; comparing the actual total weight with the actual settlement total weight to judge whether theerror is within a preset range or not, if yes, judging that there is no order escape phenomenon, entering a payment step, and if not, judging that there is an order escape phenomenon, performing reminding. The embodiment of the invention further provides a device for assisting the self-service checkout machine in preventing order escape. According to the invention, the self-service settlement machine can be assisted to effectively avoid a bill evasion phenomenon, and the implementation cost is low.

Description

technical field [0001] The invention relates to the technical field of commodity trading, in particular to a method and device for assisting self-service settlement machines to prevent escape orders. Background technique [0002] At present, more and more supermarkets, shopping malls and other commodity trading places are equipped with self-service settlement machines, which can not only reduce the cost of manual settlement, but also effectively save customers' waiting time in line and improve the shopping experience. However, in practice, it has been found that when customers make self-service settlement through self-service settlement machines, there is a phenomenon of order evasion, that is, a certain number of commodities do not enter the settlement process, and there is a phenomenon of missing settlement or less settlement. [0003] In order to avoid the occurrence of the above phenomenon, different commodity trading venues usually adopt different schemes for different ...

AI Technical Summary

Problems solved by technology

[0004] 1. Ordinary manned supermarkets mainly arrange loss prevention personnel to monitor the customer's settlement process, but the loss prevention personnel have limited energy, resulting in limited effect of preventing order evasion, that is, poor reliability, and at the same time, increase labor costs to a certain extent

[0005] 2. Ordinary manned supermarkets mainly attach acoustic and magnetic labels to each item for more expensive items, and the labeling itself increases the actual cost of the item. Therefore, non-standardized packaging for vegetables, fruits, meat, seafood, etc. that requires on-site weighing Acoustic and magnetic labels are attached to products, which are basically not operable

[0006] 3. Unmanned supermarkets or self-service vending cabinets mainly attach RFID tags to each product, and the price of RFID is higher (about 0.3 yuan each), and the use process is more complicated. Similarly, for vegetables, fruits, meat, Non-standardized packaged goods such as seafood that require on-site weighing cannot be tagged with RFID tags
