METHODS AND SYSTEMS FOR SECURITY AUTHENTICATION AND KEY EXCHANGE
First Claim
1. A modular Point-Of-Sale (POS) terminal comprising:
- a payment controller having a first encryption sub-component;
a display in communication with the payment controller;
a user interface having a second encryption sub-component, the user interface comprising at least one of a payment keyboard and a payment card reader, wherein the user interface is configured to receive financial data; and
wherein the financial data is encrypted prior to transmission in the modular POS terminal, and wherein the modular POS terminal is configured to detect tampering with the modular POS terminal.

Abstract
This is for a payment device that may be constructed from separate modules in a secure fashion such that the aggregation of the modules constitutes an overall secure device without the use of additional covers, cases, or tamper-resistant housings. The methods and system are provided whereby the devices within a modular payment system can exchange data between each-other in a secure fashion. While data encryption is being used elsewhere, the present invention extends the security zone from each secure payment module within a modular device out over the cable to the next device. This allows the user to purchase payment device components, place them as they see fit, and not have to obtain certification on their end product as a POS-A level payment device.
