This paper deals with the analysis of digital wallets for contactless cards, a technology that enables safe and convenient electronic payment without the need for physical contact. Digital wallets are becoming more and more popular thanks to their simplicity and speed of transactions, and the fundamental part of such systems are contactless cards primarily based on NFC technology. This technology enables the transfer of data between devices over short distances and is particularly useful in payment, identification and authorization processes. The paper explores key aspects of digital wallets, including the programming languages most often used in their creation, security methods, types of electronic payments, and the EMV standard for contactless cards. The practical part of the work includes the development of an application for the Android platform that uses NFC to scan contactless cards, read data in accordance with EMV standards, and simulate an NFC scanner. The conclusion of the paper indicates the importance of the further development of digital wallets, especially in the context of the increasing acceptance of contactless cards in everyday transactions and their potential in shaping the future of electronic payments.
