The "rapid response" code, or QR code, is made to quickly decode vast amounts of data. Any managed device, such as a smartphone, is able to capture it, and it is simple to access simply scanning the 2D matrix code. The dataset is analyzed utilizing machine learning techniques, such as the confusion matrix score utilized for the multinomial naive Bayes algorithm's performance analysis. The QR code generation is limited to single product and is extended now to include all products. Due to its ability to provide clients with benefits including speedy, error-free access and the ability to store a lot of data. Generally, many people are using the online payment for any transaction for flexibility and one can do at any place at any time. For bulk or huge payment, cash is not a good option. Hence many retailers join in the e-wallet companies and make their payment so flexible and faster transaction. Because of these benefits, QR code has becoming widespread.

Save Karang Mumus is a learning game about caring for the environment. This game is an educational game that can provide knowledge to players so that players are expected to learn while playing. Save Karang Mumus Game uses a role-playing game genre where players must play a role to complete the mission of the game. Multimedia Development Life Cycle development method is used for the development of this game starting from concept, design to distribution. This research focuses on the behavior of NPCs that change based on certain conditions using the Finite State Machine (FSM) method. NPCs will chase players based on the variable amount of trash collected and Health Points. The game is tested using alpha test and beta test. Based on the results, the game can be played well and get a percentage value of 65.66% of the respondents' test results. An application can be said to be good if it is more than 61% and less than 80%. It can be concluded that Save Karang Mumus Game is successful and worthy to be played.

In today’s digitally driven world, many small to medium Scale Enterprises (SMEs) find it difficult to manage or scale businesses due impediments in procuring and managing digital and software services. Many SMEs are unable to purchase the off-the-shelf software, as they are not tailor-made for their specific business use-cases and at times may not even fulfill the requirements. Creating custom software applications is an expensive undertaking and is difficult to maintain and scale. Further, the cost of deployment of these applications and ensuring availability either on premises or on cloud becomes a major hurdle. To overcome these hindrances, in this paper we propose the use of function-as-a-service technology in comparison to other options like micro-services and Service Oriented Architecture (SOA) and have highlighted the benefits in terms of ease of development and managing further we have put forth some economic benefits they have. FaaS can prove to be a major game changer service as it follows the model of pay-as-you-use and at idle time it can even scale to zero usage. This paper mainly discusses the option of using FaaS to help SMEs scale their application while cutting down on initial cost as well as economic impact in long run as compared to the other more traditional digital software service delivery models such as SaaS, ERP and custom application development.

This paper proposed a possible next-generation e-commerce “Home Décor Marketplace” system with web 3.0 capabilities to disrupt the traditional furniture and home décor retail market in developing countries like Pakistan. This project involves the development of a B2B and B2C furniture and home décor e-commerce marketplace application. The platform will allow manufacturers and retailers to list and sell their products directly to consumers as well as to other businesses. One of the main objectives of the project is to provide a convenient and efficient platform for both buyers and sellers in the furniture and home decor industry. The document describes the research work, analysis, design, and development of the platform. The proposed e-commerce marketplace has been developed based on market research. The application has been designed to be compatible with various platforms such as Web, iOS, and Android, utilizing the Google Flutter development tool. It is secured using user authentication, and the features have been carefully chosen to meet the market demands and requirements. This research paper will discuss all the technologies and tools used to build and implement an Innovative Home Decor Shopping Experience-based e-commerce platform.

The growing number of web applications in a developing country like Bangladesh has led to an increase in cybercrime activities. This study focuses on measuring the vulnerabilities present in financial and government websites of Bangladesh to address the rising security concerns. We reviewed related works on web application vulnerability scanners, comparative studies on web application security parameters, surveys on web application penetration testing methodologies and tools, and security analyses of government and financial websites in Bangladesh. Existing studies in the context of developing countries have provided limited insight into web application vulnerabilities and their solutions. These studies have focused on specific vulnerabilities, lacked comprehensive evaluations of security parameters, and offered a limited comparative analysis of vulnerability scanners. Our study aims to address these gaps by conducting an in-depth analysis using the OWASP ZAP tool to scan and analyze risk alerts, including risk levels such as high, medium, low, and informational. Our investigation unveiled eight key vulnerabilities, including Hash Disclosure, SQL injection (SQLi), Cross-Site Request Forgery (CSRF), missing Content Security Policy (CSP) headers, Cross-Domain JavaScript File Inclusion, absence of X-Content-Type-Options headers, Cache-related concerns, and potential Cross-Site Scripting (XSS), which can lead to revealing hidden information, enabling malicious code, and failing to protect against specific types of attacks. In essence, this study does not only reveal major security weaknesses but also provides guidance on how to mitigate them, thereby playing a vital role in promoting enhanced cybersecurity practices within the nation.
