Abstract

Systems and methods for the secure processing of electronic transactions are disclosed. In accordance with an exemplary embodiment, a system and method for the secure processing of electronic transactions comprises: receiving, by a POS terminal, information for a financial transaction card; receiving, by the POS terminal, information for a financial transaction; encrypting, by the POS terminal, the financial card information and the financial transaction information into a first encrypted message; transmitting the first encrypted message to a regional chassis; encrypting, by the regional chassis, the first encrypted message into a second encrypted message; transmitting the second encrypted message to a central chassis; decrypting, by the central chassis, the second encrypted message into a decrypted message; and transmitting the decrypted message to a host processor for authorization.

Claims

1. A method for electronically processing transactions, comprising:

a) receiving, by a point-of-sale (POS) terminal, information for a financial transaction card;

b) receiving, by the POS terminal, information for a financial transaction;

c) encrypting, by the POS terminal, the financial card information and the financial transaction information into a first encrypted message;

d) transmitting the first encrypted message to a regional chassis;

e) encrypting, by the regional chassis, the first encrypted message into a second encrypted message;

f) transmitting the second encrypted message to a central chassis;

g) decrypting, by the central chassis, the second encrypted message into a decrypted message; and

h) transmitting the decrypted message to a host processor for authorization.

2. The method of claim 1, further comprising:

selecting a key from a plurality of keys for use in encrypting the financial card information and the financial transaction information; and

loading the selected key into the POS terminal.

3. A secure electronic transaction system, comprising:

a point-of-sale (POS) terminal;

a regional chassis, wherein the POS terminal is connected via a communication link to the regional chassis, wherein the regional chassis is configured to receive financial transaction information from the POS terminal and the regional chassis is further configured to encrypt the received financial transaction information; and

a central chassis, wherein the regional chassis is connected to the central chassis by a network, wherein the central chassis is configured to receive encrypted financial transaction information from the regional chassis and the central chassis is further configured to decrypt the received financial transaction information prior to sending the financial transaction information to a host processor.

4. The secure electronic transaction system of claim 3, wherein the POS terminal is configured to encrypt the financial transaction information prior to sending the information to the regional chassis.

5. The secure electronic transaction system of claim 4, wherein the POS terminal is configured to encrypt the financial transaction information using a key selected from a plurality of encryption keys.
