VeriFone, a maker of credit-card readers, wants to acquire biometric payments firm Pay By Touch, according to Pay By Touch court filings obtained by BusinessWeek. Or at least VeriFone at one time expressed in interest in such a deal. But that was probably before December 3, when the company announced it would restate earnings, citing inventory-accounting problems and then watched its share prices drop 46 percent. No deal? That would be a shame. A company that can't count its inventory buying a company that can't pay for its inventory. Sounds like a perfect match.
