Recently surfaced evidence suggests that Google will have Google Play gift cards made available soon, which will allow users to purchase apps, music and videos from the Google Play Store.
These cards will be available in $10, $25 and $50 denominations and sold through retailers like Target and Radio Shack and probably through the Google Play Store.
Google has still to officially confirm this information, but all information points towards the Google Play gift cards, being made available sooner, rather than later.
