Overview Our physical wallets are quickly becoming digitized, especially the three vital functions of making payments, proving our identity, and accessing handy items, such as tickets and keys. Hundreds of digital wallets already exist. But these are textbook examples of vendor lock-in: when we can’t move our data, we can’t choose between competing products. Without interoperability, we need a separate wallet for each different function. Many of today’s digital wallets also suffer from problems such as questionable security, intrusive business models, black-box design, and limited capabilities. We need a wallet engine to help developers create portable and secure digital wallets that anyone can use on any device, with any operating system, for any app or service, with any currency, in any language, anytime, anywhere. The Open Wallet Foundation (OWF) was formed to make this dream a reality by creating an open source software engine and best practices to support it. Then, any developer can use that engine to build a digital wallet that will share data and interoperate with every other wallet built around the same codebase. As a project of the Linux Foundation, the OWF brings together hundreds of people from all over the world: from digital identity activists, standards organizations, and governments to billion-dollar companies in banking, credit cards, and software.
