ACKNOWLEDGEMENTS During the time that I was working on the project, I received a considerable quantity of support that was of great use to me This assistance provided as an impetus for us overcome all difficulties and problems that emerged and bring about the successful completion of this challenging but important undertaking To begin, I would like to express my gratitude to the School Board of the Ho Chi Minh City University of Technology and Education as well as the Faculty high-quality training Faculty supports me with and thereby allowing me to continue with my project Without their assistance, I would not be able to move forward with it Second, we would like to use this opportunity to extend our most sincere gratitude to Mr Truong Ngoc Son, who assisted us with this project in a consulting capacity Both of these things, Mr Truong Ngoc Son pointing us in the proper direction and providing us with vital directions, contributed to the fact that we were able to finish our job successfully By putting these ideas into action, not only will we be able to rectify any errors that have been committed, but we will also be able to bolster the foundation of our project I would like to express my gratitude to all of the helpful students who were enrolled in the 18161CLA class This is the last but not the least of my points of appreciation Whenever it was required, these pupils were always happy to give aid in the form of guidance in the form of counsel and teaching that was kind In a word, I would want to express my sincere gratitude to everyone who had a role in the success that we have just accomplished swipe their payment card Currently, the staff must manually review the order and total amount in the software 4.2 Operation of system 4.2.1 Sales management interface The program responsible for order processing, system operation, commodity codes, and user management The following page will show the first time you run the software, asking that you check in to your account This step must be completed in order to continue use the program Figure 27: Sales interface Next when we log in, a successful login window will appear on the screen 40 Figure 28: User login When visiting the payment interface, a payment window will display On the left side of this window is a list of product details, including the order number, the item's name, the product code, and the unit price The interface for recognizing the product's image will be shown on the right side of the window The most significant part will be the interface for paying for the things, which will indicate whether products are acknowledged Figure 29: Interface for processing, payment of orders and application of the system 41 4.2.2 Database SQLite data: Among the data stored are: a warehouse, users, and login accounts We could find information pertaining to the payment cards of clients, login information for company owners, and information on commodity codes at a facility that stores data Figure 30: Database The table contains information pertaining to the following several categories: barcodes to identify the product, as well as monetary reimbursement for each individual item Figure 31: Storage facilities 42 In the table is shown the information that corresponds to the payment card that the consumer has contains information on the number of cards that are still available as well as the amount of each card that is still available Figure 32: Payment card User interface for the administration of information relevant to individual consumers At this point in the process, we have the choice of registering a new card by swiping the card, generating a username for the card, and adding money to the card Alternatively, we may choose not to register a new card and continue with the operation Following the scanning of the cards and the entry of the proper amount, we finally get to the step of adding the money By doing so, you may be certain that the appropriate amount will be added to each card 43 Figure 33: Customer information management interface A table featuring fields for the collection of information about customers, such as their retail establishment login name and password Figure 34: User 44 4.2.3 Identification of products A position that involves the labeling of products When the product on the conveyor belt reaches the end of the belt and passes through the scanner, a camera system equipped with image recognition software will be able to identify the product When the product reaches the end of the conveyor belt, this will occur When the product reaches the end of the conveyor belt, where it will be halted for inspection, this will occur If both the barcode and the image of the goods have errors, the system will send a warning to the seller This will allow the seller to evaluate the order for the customer's benefit, which will be advantageous for the vendor If the information presented on the screen and the information contained in the barcode are same, the system will display the barcode Figure 35: A resource bill 45 Figure 36: Identification of products 46 The accuracy of the model that was used for product identification was maintained by taking into account both the scan code and the information on the customer's purchase This was done in order to retain the correctness of the model This indicated that the model was capable of maintaining its accuracy throughout its whole The maintenance of both of these aspects of the data made it feasible for us to accomplish this goal in a manner that was both timely and satisfactory Not only does this information contain the overall price of the purchase, but it also includes the amount of each item that was purchased as well as the total number of goods that were obtained Figure 37: Payment 47 The whole amount of the order will be shown on the LCD screen, which is also where customers can see the payment interface that the store has made accessible Due to this precaution, after the customer has completed their purchase, they will have piece of mind in knowing that they are completely aware of the worth of the item or items that they have purchased Figure 38: Payment success 48 4.2.4 The role of the barie Barie bars are intended to open and close so that clients may get their purchases upon payment After a certain amount of time, the barrier automatically lowers This describes the condition of an open bar Only once the customer has paid for the item can they access it After payment, the barrier will open, and after a period of time, it will begin to stack Figure 39 Open a barie 49 This is the current state of the barrier that is being constructed It prevents the product from being stolen without payment, which is its primary purpose Figure 40: Close a barie 50 CHAPTER 5: CONCLUSION 5.1 Result During the implementation of the project, it helped our group understand more deeply knowledge as well as draw some lessons learned and give some comments on the feasibility of applying this problem in the field Various contexts such as: - During the research process, we have applied the knowledge we have learned and learned more new knowledge to complete the set requirements - The product works 90% of the required - The circuit works stably and accurately when switched on and off many times - Simple circuit, compact, easy to assemble and repair, few components and only use components available on the market, automatic and secure closed payment model, simple and fast payment save labor 5.2 Development Although the system has worked well, the camera's item recognition mechanism is still slow due to the weak configuration of the computer, it is necessary to upgrade a computer with more advanced hardware to overcome the delay when scanning products products by camera Products in the list are few, try to add more products to make the product system more diverse Combined with the product self-packing system to produce the product that is packed in the box Develop more payment possibilities, can pay in cash using artificial intelligence for money recognition 51 PREFERENCES [1] Hui,
