The evolution of digital wallets: Cloud, IoT, and blockchain synergy in credit card services

There are new possibilities resulting from the progress of cloud technology, IoT, and blockchain as regards the development of digital wallets. In this paper, I identify how these technologies intertwale to define the current state of digital wallets. Thus, cloud computing also forms the basis for the protection, as well as the scalability and availability of the payment details, for multiple-device usage. IoT is an extension of digital wallet wherein payments can be made from any device, based on context and can be made automatically. Blockchain is the technology of decentralised and immutable records of data assets, which contributes towards the security, efficiency and integrity of monetary digital currencies and the completion of their transactions. Thus, describing the collaboration of these technologies, this paper outlines the changes in the concept of a digital wallet and future development of the field.
