A visually challenged person may find it challenging to distinguish between various denominations of currency. For those who are blind, this process is still challenging even though most of the Indian currency is written in unique characters. Portable solutions for isolation have emerged because of a shortage of available tools. This study details the creation and evaluation of a new assistive technology that uses an easy-to-use currency detection system to improve the financial independence of people with visual impairments. The apparatus employs sophisticated image processing techniques and deep learning algorithms to precisely recognize different banknote denominations. A compact, user-friendly interface that provides audio feedback to convey the denomination to the user ensures ease of use and privacy. A portable computer device connected to a high-resolution camera forms the basis of the system architecture. On this device, a convolutional neural network (CNN) model is trained using many datasets of cash photos in various orientations and light conditions. A high recognition accuracy rate is attained by the model, which is essential for real-world uses. Voice commands and tactile buttons work together to make it easy for users to engage with the gadget. Many daily living tasks are made more difficult by the prevalence of visual impairment, particularly those that require the recognition of currency, leaving the affected person dependent on others to complete financial transactions. Its ability to quickly and accurately identify different currencies and output format in audio feedback has proven to be highly beneficial for those with visual impairments who travel or live in multicultural environments. Moreover, positive feedback from user experience evaluations indicates that the system's practical impact extends beyond its technical achievements, with considerable improvements in confidence during financial transactions and ease of use. To ease that dependency, a unique Currency Detector System (CDS) made especially for visually impaired individuals has been created.
