在本文中，我们提出了一个近场通信为基础的移动的P2P支付应用程序，称为mFerio，旨在取代基于现金的交易的设计和评估。我们首先确定支付系统应该满足的设计标准，然后解释mFerio如何相对于这些标准，改进基于现金的系统的局限性。接下来我们将描述mFerio的实现和用户界面设计，重点是可用性和安全性之间的平衡。最后，我们提出了一个两阶段的用户研究的结果，涉及共104人，这表明mFerio具有较低的认知负荷，也是快速，准确，易于使用-甚至优于现金的速度和认知负荷在常见的支付情况。
In this paper, we present the design and evaluation of a near-field communication-based mobile p2p payment application, called mFerio, that is designed to replace cash-based transactions. We first identify design criteria that payment systems should satisfy and then explain how mFerio, relative to those criteria, improves on the limitations of cash-based systems. We next describe mFerio's implementation and user interface design, focusing on the balance between usability and security. Finally, we present the results of a two-phase user study, involving a total of 104 people, that shows that mFerio has low cognitive load and is also fast, accurate, and easy to use - even outperforming cash in terms of speed and cognitive load in common payment situations.
