An access device comprising:

• a processor;
• and
• a non-transitory computer readable medium, the non-transitory computer readable medium comprising code, executable by the processor, for implementing the methods comprising:
• transmitting, to a smart device, a first message including data associated with a transaction;
• logging the transaction in a transaction log;
• suspending the transaction;
• receiving, from the smart device, a second message including a command to resume the transaction;
• retrieving the transaction from the transaction log;
• receiving, from the smart device, a cryptogram;
• generating a transaction authorization request message including the cryptogram and the data associated with the transaction;
• transmitting the transaction authorization request message to an authorizing computer;
• and
• receiving, from the authorizing computer, a transaction authorization response message authorizing or declining the transaction.

A method comprising:

• receiving, at a smart device, first interaction data from an access device in a first message;
• temporarily storing, by the smart device, the first interaction data while waiting for an interaction with a portable device;
• providing, by the smart device, the first interaction data to the portable device, after the portable device interacts with the smart device;
• receiving, by the smart device, second interaction data from the portable device in a second message, the second interaction data including a cryptogram encoding the first interaction data;
• providing, by the smart device, the second interaction data to the access device, wherein the access device generates and transmits an authorization request message to a transaction processing computer for authorization of a transaction,
• wherein the first message and the second message are part of a set of messages used by the access device complete the transaction.
