Systems, methods and devices for transacting

A system for conducting a transaction based on account credentials associated with a consumer, the system comprising:

• a mobile device of the consumer having an associated alias, the mobile device comprising:
• a secure store integrated circuit including a first cryptoprocessor coupled to a first secure memory storing:
• a mobile-based credential, the mobile-based credential being a decryption key corresponding to encrypted account credentials stored at a remotely accessible server as a server-based credential;
• and
• a first set of instructions, which when executed by the first cryptoprocessor, causes the secure store integrated circuit to release the mobile-based credential in response to receiving a correct passcode associated with the mobile-based credential;
• a secure accessing integrated circuit including a second cryptoprocessor coupled to a second secure memory storing a second set of instructions, which when executed by the second cryptoprocessor, causes the secure accessing integrated circuit to:
• receive a request for the mobile-based credential from the remotely accessible server, the request being generated by the remotely accessible server in response to receiving the alias associated with the consumer from a merchant terminal;
• prompt for entry of a passcode associated with the mobile-based credential;
• receive the passcode associated with the mobile-based credential;
• transmit the passcode to the secure store integrated circuit;
• access the mobile-based credential from the secure store integrated circuit in response to the secure store integrated circuit verifying the passcode is correct;
• and
• transmit the mobile-based credential to the remotely accessible server, the mobile-based credential being the decryption key decrypting the server-based credential stored at the remotely accessible server to obtain the account credentials for completing the transaction.
