<p>The invention relates to a gateway for providing point to point encryption (P2PEG) for the communication of sensitive data for card-present transactions from a card reading device to a transaction processing system using a communication network, the sensitive data for a transaction being encrypted at the card reading device such that said encrypted transaction data is transmitted from the card reading device through a merchant environment towards said transaction processing system,wherein the encrypted transaction data is redirected via said P2PEG 3.9; wherein the P2PEG comprises a secure decryption module (SDM) for accessing a decryption key for decrypting the encrypted transaction data; and wherein, responsive to the receipt of the encrypted transaction data at the P2PEG, the SDM is configured to decrypt the encrypted transaction data such that the decrypted transaction with the sensitive data is transmitted to the transaction processing system via the communication network. The invention also relates to a system incorporating the gateway (P2PEG) and method for implementing point to point encryption of sensitive data. The gateway,system and method of the present invention are capable of providing P2PE for a payment transaction system without requiring any significant changes to be made to an existing transaction processing system,such as an existing Payment Service Provider (PSP) system.</p> |
