Google revealed a dizzying number of projects at this year's Google I/O event, and it is courting developers to turn each of them into a thriving commerce platform. Whether or not Android Pay was mentioned by name, it was an undercurrent of nearly every offering. (Pictured: Google CEO Sundar Pichai)

Instant Apps

The biggest barrier to mobile commerce is getting the user to download an app and set up an account, particularly for brief interactions like parking payments. Google's Instant Apps project eliminates all of those steps, letting lightweight versions of apps instantly load for one-time use — and tying them to Android Pay to handle payments.

API for E-Commerce

E-commerce shares the same hurdles, which is why Google developed the PaymentRequest API. A merchant that uses this API can accept Android Pay payments from within the Chrome browser, and the shopper can approve the purchase with fingerprint authentication.

Bank of America's revenue may decline 1 percent in 2016, similar to 2015, before growing 6-7 percent in 2016-17, based on a consensus of analysts in a Bloomberg Industries report published in April.

Bundled with Banks

Banks can also link their apps to Android Pay by providing ATM access or by linking a payment card to Google's mobile wallet. Bank of America has already teamed up with Google for ATM access.

Android Pay Rewards

Android Pay has a role in the physical world as well, and Google plans to make the most of the NFC readers merchants have placed in their stores. In addition to paying for purchases, Google wants NFC to power consumer registration for store loyalty accounts.

In the Home

Google's voice assistant will be a big part of its Google Home and Android Auto products, which allow users to make queries — and payments — whenever these devices are within earshot.

Allo and Assistant

Google is also putting more digital brainpower into its mobile apps. The upcoming Allo messaging system will treat the Google assistant as a party to any conversation, allowing texters to make restaurant reservations or order products without leaving the chat window.

Android Wear 2.0

The next iteration of the Android Wear smartwatch platform still doesn't seem to require NFC for payments. But it does allow developers to break the wearable's reliance on the phone, and lets watchfaces connect to any app — including commerce apps — rather than show only a subset of device-specific stats.
