A digital wallet is a system that securely stores users' payment information and passwords for numerous payment methods and websites in a cloud. This software-based system allows financial instruments such as bank and credit cards to be defined in one place. They can be updated or deleted as needed, and payment history can be viewed. Additionally, it is possible to store loyalty card information, digital coupons, gift cards, hotel reservations, and flight information in a digital wallet. This way, consumers can easily access important documents and not miss out on benefits during their shopping experiences.
