Is Google (NASDAQ:GOOG) ready to swap some virtual coinage? Yesterday, uncovered a signup page for Google Purchases at the subdomain.

Smoked out, Google went on to redirect that traffic to the general Google Accounts page, but not before a screen shot all but confirmed that Google is nearing the beta rollout of its online financial payment service.

This move has been rumored for months now. Google has even gone on record over the summer to explain that the eventual offering is not aiming to compete with eBay's (NASDAQ:EBAY) popular PayPal subsidiary. Its original intent appears to be simply to give Froogle merchants and AdWords advertisers a new alternative to conduct business with Google, and Google alone. The system is tied to a user's credit card -- not the more PayPal-like personal bank account. Even the name -- "Purchases" -- is dry and corporate. If Google were gunning for the general consumer market, surely it would have picked something more casual like Google Pay, Goopay, or Google Cash.

Then again, how things start and how they wind up years later is often beyond anyone's control. If Google's work on Purchases has the same level of excellence that the search king has shown in everything from Google Earth, Google Local, or the flagship search engine, how can Google Purchases not catch on -- and cash in -- on the mainstream masses?

And why would Google dedicate resources to creating a worthy virtual transaction service that it couldn't easily port into a consumer-to-consumer platform? If Google's advertising model relies on the volume and quality of eyeballs, how can it not want to be a more sticky component to users looking to exchange money online? Even if Google believes that this isn't the direction that Purchases will be taking, I'll "Google Purchase" you a virtual buck in a few years if this isn't the logical hitching post for what this upcoming service will evolve into.

It won't be easy, though. Rolling out an online payment service has been hard unless your name is PayPal. Yahoo! (NASDAQ:YHOO) shuttered its PayDirect service last year. Microsoft (NASDAQ:MSFT) also gave up promoting its Passport feature to third parties. Even eBay's own Billpoint payment service couldn't topple PayPal. That's why eBay, a Motley Fool Stock Advisor recommendation, ultimately bought PayPal. Google will make things interesting, though, even if it keeps asking folks to move along because there is nothing to see here.

There is something to see here, though. One just needs to look harder, and further out.
