Abstract
A method and system are presented for making a secure payment transaction using a payment card associated with a consumer which has been registered with a digital wallet. A secure server is arranged, in response to a request from a merchant server in relation to the consumer, to extract from the digital wallet payment credentials for the payment card. The secure server uses the payment credentials and the identity of the merchant server to generate a token. The token is provided to the merchant. To effect a payment transaction, the merchant server returns the token to the secure server with details of the desired payment transaction, and the secure server arranges for the payment transaction to occur, and notifies the merchant server. The merchant server does not receive the payment credentials of the payment card during this process, so even if its security is compromised, the payment credentials are not at risk.
