This app can be thought of as your real-life wallet: it stores many pieces of information - an ID, a discount code, a loyalty or credit card, a ticket or a document, etc. - and you present them whenever they need to be verified by a service, an organisation or such, then you put them back into your pocket.

Inside the Transponder, your data is safely stored within signed Verifiable Credentials (for the sake of the metaphor, think of them as cards), which are validated through your digital identity and can be used across the web only with your direct permission.
Locally stored within your mobile

Your unique digital identity is created and stored inside your mobile when you download the app, so that you can exchange data through it: this means enhanced security, since no information is valid without being paired with your device, therefore providing implicit two-factor authentication.
Accept or provide credentials

With the Transponder app, you can accept verifiable credentials and store them safely, in order to use them as needed across websites, services, web-apps. You can provide one credential to login without email or passwords on multiple websites, one to authorise payments without inputting your card details, one to perform a KYC or Bank Account verification procedure, and so on.
t is the place where you can store, manage and share your data, identity and much more with other organizations.
