Amid the rise of mobile payments, credit cards aren't disappearing just yet, according to Citi Cards CEO Jud Linville. 'I keep wondering when cards are going to disappear,' Linville said. 'Cards are easy - whether it's a swipe that's easy or the tap and pay that's easy - I think you're going to see integration of all of those over time.' Citi Cards is a division of Citigroup (C) - Get Report . Amid the rise of Apple Pay from Apple (AAPL) - Get Report , Samsung Pay and Alphabet's (GOOGL) - Get Report Android Pay, Linville said there are still hurdles that will keep the traditional credit card around longer. 'There's a hurdle of trust and a hurdle of complexity,' Linville said, referring to the digital payment platforms. 'Credit cards still are heavy in use.'
