Visa and Samsung ink worldwide NFC deal, practically guarantees payWave on your Galaxy S IV

First, the good news. It appears that Visa and Samsung's Olympics trial went over so well, that it's expanding those mobile payment dreams to a global audience. Now, the rough news -- Visa has convinced Samsung to pre-load the payWave app onto every future Samsung smartphone with an NFC module. Granted, you'd be using that anyway for contactless payments... but only if you had a Visa card. At this point, it's practically a given that the impending Galaxy S IV will boast not only an NFC chip, but payWave integration from the factory.

The deal also gives banks the ability to load payment account information over-the-air to a secure chip embedded in Samsung devices (thanks, Mobile Provisioning Service), but neither company is coming clean on what devices in particular will be taking advantage. Unfortunately, this news may be even gloomier for non-Visa users -- it's unlikely Samsung's contract will allow it to announce similar deals with competing mobile payment services, but we suppose we'll see in time.
