Abstract: An online transaction system configured to implement authentication methods that allow for strong multi-factor authentication in online environments. The authentication methods can be combined with strong security methods to further ensure that the authentication process is secure. Further, the strong multi-factor authentication can be implemented with zero adoption dependencies through the implementation of automated enrollment methods.

Abstract: A compressor system has a compression stage, a coolant circuit and a refrigerant circuit. The compression stage compresses ambient air and generates compressed air and heat. A coolant removes heat from the compression stage and the heat is transferred from the coolant to a refrigerant. A refrigerant expansion device is incorporated into the refrigerant circuit. The expansion device expands the pressurized refrigerant utilizing a rotary expander. Energy generated during refrigerant expansion is captured and used to drive components of the cooling system.

Abstract: A method of and system for authenticating a transaction initiated from a non-internet enabled device (101) is disclosed. In broad terms, this invention defines systems and methods that enable Issuers (107), Acquirers and Merchants (105) to use existing online cardholder authentication protocols to authenticate cardholders transacting with non-internet enabled devices. In particular, the invention operates as a proxy on behalf of the cardholder and simulates a conventional cardholder authentication session to a Merchant Plug-in (105) and Issuer ACS (107). That is, it converts voice or data based messages received from non-internet enabled devices (101) into a format that is consistent with the requirements of the existing online cardholder authentication protocols.
