Wells Fargo Tests Microchips for Globetrotting Card Clients

Wells Fargo & Co., the U.S. bank with the most branches, is testing microchip-embedded credit cards with frequent travelers to address complaints of customers who have trouble using their cards abroad.

The pilot program announced today marks the first effort by a major U.S. bank to deploy Visa Inc. credit cards with so-called EMV-chip technology, which has become a standard in Europe and much of the rest of the world, according to San Francisco-based Wells Fargo.
