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.
