Abstract
A method of authenticating a payment terminal to a computer server involves the terminal generating a terminal activation request from a private key uniquely associated with the terminal, and from a credential uniquely associated with the terminal. The activation request includes a public key that the payment terminal generates from the private key. The private key is both provided to and uniquely associated with the terminal by an entity other than the terminal prior to the terminal generating the activation request. The terminal transmits the activation request to a certificate server, and receives a digital certificate in response. The terminal initiates a transaction with a network client by authenticating to the computer server using the digital certificate. The computer server is in communication with the network client via a communications network. The terminal effects payment for the transaction via an acquirer network distinct from the communications network.
