Abstract
A data-carrying device and methods of authenticating the same are disclosed. The data-carrying device is described as being capable of communicating via the Near Field Communications (NFC) protocol and may have one or more NFC Data Exchange Format (NDEF) records stored in its memory. The data-carrying device also comprises or has the ability to generate a signature that proves the data-carrying device is the authorized device for storing the one or more NDEF records. A data-carrying device that attempts to transmit an NDEF record without a valid signature may be identified as an unauthorized data-carrying device.
