This app is a companion to the zk-creds anonymous credentials framework. This app dumps the contents of an NFC-equipped passport to a JSON blob. That JSON can then be used to create an anonymous credential in the zk-creds scheme. Prebuilt APKs can be found in the root directory of this repo.
- Open the app and enter in the requested passport information. This is necessary because the data on the passport's NFC chip is encrypted using this info.
- Place your device on top of your passport. You may need to move it around to get it to work. It will vibrate when it finds the chip.
- Keep the device in place until reading is done.
- Once reading is done, you will be prompted to share a large JSON blob of text. Share this with yourself using whichever secure means you prefer (e.g., Signal's Note to Self feature)
This app is only possible thanks to Anton Tananaev's work. Original repo is here.
