Smartphones built from an Intel reference design will use near-field communications technology to tie up with Visa's PayWave mobile-payment software, the companies have announced. Separately, the Isis Mobile Wallet will soon work with credit, debit and prepaid cards issued by Barclaycard, Capital One and Chase, with the service being tested later this year in Austin, Texas, and in Salt Lake City. Meanwhile, a MasterCard executive said the credit card isn't rapidly fading away as mobile-payment systems take hold around the world. "There will be a period of co-existence for a long while," said James Anderson, the company's head of mobile development.
