| 20130013515 | Secure Payment Device with Separable Display - A secure terminal, such as one used for point-of-sale debit card transactions, has a secure enclosure containing some or all of the terminal components, and is configured to send sensitive and non-sensitive data to a display located outside of the secure enclosure. The terminal includes a source chip that protects data sent from the terminal to the display. The source chip protects the data by detecting that the display is connected, authenticating the display as a device that is authorized to receive the data, and encrypting the data before transmission. Preferably, the display is a commercially-available consumer electronic device, such as a television or computer monitor. The source chip communicates with a receiver chip on the display to perform the detection, authentication, and encryption methods of the invention. | 01-10-2013 |
