Bill Gajda, Visa’s global head of mobile products, outlined the credit card giant’s strategy in mature mobile markets as well as the developing world during his keynote presentation at the 2012 GSMA NFC & Mobile Money Summit in Milan. In the latter markets, that approach includes Visa Mobile Prepaid. In the former markets, its strategy includes its PayWave technology, device certification and V.me, its digital wallet. However, Gajda noted that these two very different markets are showing signs of convergence.
