ENHANCED NEAR FIELD COMMUNICATIONS ATTACHMENT

摘要

A secure fob that enables a user to pay for an item or items without needing to present a mobile device. A secure fob may include a proximity capability to ensure that a mobile device is within a particular range, thereby eliminating the risk of fraudulent charges on a stolen fob. In such an embodiment, a fob may be disabled if the fob is not paired with the mobile device by virtue of being disconnected and/or physically separated from the mobile device. The secure fob also may include enhanced features to authorize transactions and locate the mobile device and/or the secure fob.
