问答题 Every day brings news of new developments in mobile payments and mobile-pass technology. So when can we finally get rid of our wallets? Not for a long time, unfortunately - at least a decade. Even if your current smartphone is technologically capable of handling payments, passes and membership cards, and IDs, the real infrastructure will take up to a decade to get fully sorted out. For payments, especially, smartphones are taking on a lot of the functions of our wallets without fully replacing any of them, “Before all venues accept payments with a smartphone, consumers cannot ditch their wallets, ” Oren Levy, CEO of in-app payment platform ZooZ, said via email. “Otherwise, I will be able to pay at one store but not at the next one. For all merchants to accept payment with a smartphone it will take at least 10 years. ” Forrester Research estimates only one-fourth of U. S. consumers will own an NFC-enabled phone by 2016, with 100 million shipping in 2012. Until a solid majority of consumers own such devices, merchants have little incentive to create an infrastructure as receptive to smartphone payments as it is to cash and credit cards. That is the largest hurdle wallet-abandoning hopeful face.无
