Consumers swiped their Visa debit and credit cards more often, and ran up higher tabs, driving better-than-expected first-quarter results for the world's largest card processor. Visa (V) earned $1.82 a share for the December-ending quarter, after backing out a one-time per-share tax gain of 11 cents. That was up 22% from a year ago, and 3 cents per share higher than the consensus estimate of analysts surveyed by Thomson Reuters.
