For security researchers and demonstration purposes only.

This app demonstrates a vulnerability in Google Wallet that makes it possible to reveal the user's PIN. This defeats all of the security provided by the Secure Element in the NFC device.

This app requires root access and a working installation of Google Wallet (which requires a phone with NFC). It also requires at least Android 3.2, so Nexus S users will have to wait until their phone's are upgraded.
