Android Central has published what it claims are vouchers for the online marketplace valued at $10 and $25.
The website claims that the gift cards will be available from high street retailers, and will be redeemable for music, movies, books, apps, and more.
Google's main competitor Apple has offered vouchers for its iTunes store for some time, and their introduction sparked an increase in revenue for the service.
The search engine giant revamped Google Play this summer with the introduction of new content and services, such as movie rentals in various territories and magazines in the US.
Google is yet to officially confirm plans to introduce Google Play gift cards.
