# What are Reward Programme Apps? Through ecosystem participants including Single.id, Vow enables companies from any sector with large customer bases, such as banks, insurers and loyalty business to enrol their End Users in a Reward Programme app, and thereby participate in the benefits of the ecosystem. We term such companies “Publishers” collectively. The reason for the name is because they publish information and offers about to their End User base. Publishers can integrate Voucher currency into their existing apps using a comprehensive suite of APIs. Alternatively, white label websites and brand-able apps are waiting to be implemented. Ecosystem participants can also provide comprehensive loyalty programmes if required. All solutions integrate the same functionality of send and receive as is available to Vow App Wallet users within their existing mobile applications. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
