The document discusses digital wallets, which allow users to make electronic payments by storing virtual versions of payment cards on their mobile phones. A digital wallet works by securely storing users' payment information and card details within a software component on their device. It aims to simplify online and in-person payments by automatically filling in payment details during transactions. The digital wallet offers advantages like consolidating multiple payment and loyalty cards in one place and helping users maximize rewards earned from purchases. However, challenges remain around securely storing digital cash and ensuring digital wallet systems are fast, easy to use, and accurate.

Editor's Notes
- Extensible: a wallet should be able to accommodate user’s different payment and multiple payments protocols.Client-Driven: interaction between wallet &vendors ,we believe should be driven by the client.Symmetric: vendors & banks run software analogous to wallets which manages their end of the financial operation.Generalized: interfaces should be similar of what type of devices that the wallets, banks or vendors apps is running on.
- Software, which provides both security and encryption for the personal information and for the actual transactionInformationcomponent, is basically a database of user-inputted information.
