Code found in Google Play Store APK reveals a reward program called Google Play Points

Strings of code found in the APK from the latest version of the Google Play Store (v 11.6.15) point to the creation of a rewards program from Google. Called Google Play Points, the program hands out points to Android users who purchase an in-app item or Google Play Credit. The code shows that for every 100 Yen spent (90 cents US), buyers will receive 1 Google Play point. We wouldn't be surprised to see Google round this off to one point awarded for every $1 USD rung up in the Google Play Store.
