Apple and Google are both investigating the prospect of buying or dealing with the mobile payment firm Boku to ease mobile payments, a leak from near the company has discovered. The startup's top executives, including its CEO Mark Britto and its co-creator Ron Hirson, have reportedly been talking alternately to Apple's iPhone team leaders as well as Google Mobile Services' engineering director Michael Morrissey. Talks have been underway with at least Apple for the past three weeks, TechCrunch said, but it's unclear how likely a takeover prospect might be.
