Google has begun testing a loyalty programme, tempting people to use Android Pay with the promise of a free Chromecast media streaming dongle.
Quietly rolled out to some Android Pay users in the US last week, the Tap 10 programme sees rewards handed out for making contactless mobile payments. For those picked, the first, second and sixth payment taps each earn a free Google Play Music song, while the 10th tap - which must be carried out by the end of February - gets a $35 Chromecast.
The move comes as Google attempts to figure out the best way to encourage people to use its mobile payments service in the face of numerous rivals and consumer apathy. Android Pay's predecessor, Google Wallet, failed to take off, while the rival Apple Pay has also seen sluggish adoption.
