If the muttering we’re hearing through the Bloomberg grapevine is true, Google is planning to finally unveil their NFC mobile payment service on May 26. Google’s system is going to be available on phones from Sprint, like the already-launched Nexus S 4G. (Not so coincidentally, the Nexus S is still the only Android phone in the U.S. with NFC.)

The NFC service will let consumers both pay and use mobile coupons with a swipe of their phone. However, Google and Sprint’s offering will eventually see competition from ISIS, a joint effort between AT&T, Verizon, and T-Mobile.

Google does have a press event scheduled for May 26, but as of now, no one’s talking. Guess we’ll all have to keep our ears tuned to the latest and greatest coming out of New York that day.
