Abstract	Advanced detection techniques are necessary to stop fraudulent transactions because counterfeit currency continues to pose a danger to financial security. Conventional verification methods, such UV scanning and hand examination, have not been able to keep up with advanced counterfeiting techniques. This study investigates machine learning and image processing methods for detecting counterfeit currency to overcome these difficulties. To distinguish between real and fake banknotes, image processing techniques such as edge detection, texture analysis, color segmentation, and hyperspectral imaging extract vital security information from the notes. These methods do have several drawbacks, though, namely their high processing demands and susceptibility to changes in lighting. While deep learning models like CNNs (VGG16, ResNet, Efficient Net) do away with the need for manual feature extraction by learning complex patterns directly from banknote images, machine learning models like SVM, k-NN, and Decision Trees automate classification using extracted features to increase accuracy. Furthermore, by producing artificially created fake images, Generative Adversarial Networks (GANs) enhance training datasets and boost model resilience. Additionally, real-time authentication and decentralized security provided by blockchain and IoT integration lower the risk of fraud in financial transactions. Notwithstanding these developments, issues including data accessibility, real-time processing limitations, and the dynamic nature of counterfeiting methods still exist. To improve the precision, scalability, and effectiveness of counterfeit detection, future studies must concentrate on federated learning, adaptive AI models, and lightweight deep learning architectures. To protect international financial systems, this study compares current counterfeit detection techniques, emphasizing their benefits, drawbacks, and possible future advancements.
