Summary0009985: NFC chip continues to broadcast after detail view with QR code was dismissed
DescriptionWhen initiating a P2P send operation, the Android wallet starts sending the talerURI via NFC simultaneously with showing the QR code.
But it continues to broadcast via NFC even when the user closes the QR dialog, and even when sending the wallet to the background!

Anyone could just steal the sent money by holding their phone near the sender's phone, probably without the sender even noticing.
==> NFC transmission must be stopped when the QR code is dismissed, or the app is going to the background.
TagsNo tags attached.
