A system for encrypting and authenticating a payment transaction includes a card reader, a computing device, a card swipe application and a checkout application. The card reader includes a reader head, a secure microcontroller, and an interface. The reader head reads payment card data from a payment card. The secure microcontroller stores a unique reader identification (reader ID), and at least a first encryption key, and includes a payment card decoder application and an encryption application. The encryption application encrypts the payment card data and produces encrypted payment card data. The encryption application further encrypts the transaction data with the first encryption key and produces encrypted transaction data. The checkout application receives the encrypted payment card data and the encrypted transaction data and forwards them to a payment server for processing of the payment transaction. |
