While we focused mostly on the announcements related to Google’s new flagship products during and after Google I/O – Google Nexus 7 and on Android 4.1 Jelly Bean – these weren’t the only new things that came out of the developer conference.

In our initial Google I/O preview, we said we expected Google to unveil its rumored Google Wallet 2.0 mobile payment solution, especially considering that Apple has just announced a new iOS app called Passback, which could the company’s first steps into this business, not to mention that Microsoft unveiled a Wallet Hub of its own for Windows Phone 8, an app that can do more than just safeguarding credit card information needed for mobile payments.

Google did talk about its Google Wallet app, which is yet to become as popular or as widely used as the company would want it to be, but it did not unveil a Google Wallet 2.0 product. Instead, during one of the developer sessions at Google I/O, it introduced a new Google Wallet feature called Save to Wallet.

With Save to Wallet, customers will be able to save special offers and coupons found on various sites right inside the Google Wallet, and use them later, where applicable. The feature will remind Android device users to take advantage of the saved offers before they expire and even pay via NFC in stores, where such payment features are available. Initially, the feature will work only with a limited number of partners, but Google plans to bring more companies in and let them use the new Save to Wallet API.
