Google’s product strategists just announced the launch of Google Wallet — an NFC-based mobile payment solution. As my colleague Charlie Golvin pointed out, this is another early salvo in what will be a long and hard-fought battle to change consumers’ payment behavior and, as a potential result, the makeup of the payments landscape.

We have covered this issue in more detail in a new Forrester report “Google Wallet Is Not About Mobile Payments.” Clients can access the report here.

Given its core search business and ad-based revenue model, why would the company make that investment? Because Google’s product strategists’ focus is not on the payment itself; it’s on all of the other elements that comprise a commerce experience and the data that characterizes those elements.

Indeed, appending real-world purchase information to its treasure trove of online behavioral data will vastly increase the value of customers’ profiles and increase the rates Google can charge its advertisers. It will be a way for Google to increase its local presence. NFC is too often equated simply with payments, but Google understands that NFC tags have broad application (working like Quick Response [QR] and other 2D barcodes do today). Google can help retailers use NFC tags for in-store promotions and check-ins, augmenting the understanding of customer behavior for ad targeting.
