Point-of-sale terminal for transaction handoff and completion employing ephemeral token

A computer-readable storage medium storing program instructions that, when executed by a computer, cause the computer to perform a method for handoff of a transaction for completion, the method comprising:

• facilitating the handoff of the transaction in a point-of-sale (POS) terminal, said facilitating comprising:
• scanning one of a plurality of ephemeral transaction authorization tokens displayed on a guest device, wherein a guest has previously registered a payment instrument with a server, and associated the payment instrument with the plurality of ephemeral transaction authorization tokens, and the server has stored a payment token that associates the plurality of ephemeral transaction authorization tokens with the payment instrument in a payment token database record along with a push notification device identifier that corresponds a the guest device, and wherein the guest device has requested and received the one of the plurality of ephemeral transaction authorization tokens from the server;
• transmitting the one of the plurality of ephemeral transaction authorization tokens via the internet cloud to the server, wherein the server is not collocated with the POS terminal, and wherein communications between the POS terminal and the server are transmitted and received through a gateway device that is collocated with the POS terminal;
• simultaneously displaying details for the transaction in conjunction with the guest device, wherein the server has accessed the push notification device identifier to transmit a push notification to the guest device, and wherein the guest device has accepted the push notification and is executing a proprietary application that allows for said simultaneously displaying details for the transaction;
• and
• receiving notification from the server that the transaction is complete, wherein transaction completion data was entered via the guest device and transmitted to the server, and wherein the server has completed the transaction.

A point-of-sale (POS) terminal for facilitating handoff of a transaction for completion, the system comprising:

• input/output circuits, configured to scan one of a plurality of ephemeral transaction authorization tokens displayed on a guest device, wherein a guest has previously registered a payment instrument with a server, and associated said payment instrument with said plurality of ephemeral transaction authorization tokens, and said server has stored a payment token that associates said plurality of ephemeral transaction authorization tokens with said payment instrument in a payment token database record along with a push notification device identifier that corresponds to a guest device, and wherein said guest device has requested and received said one of said plurality of ephemeral transaction authorization tokens from said server;
• a communication circuit, configured to transmit said one of said plurality of ephemeral transaction authorization tokens via the internet cloud to said server, wherein said server is not collocated with the POS terminal, and wherein communications between the POS terminal and said server are transmitted and received through a gateway device that is collocated with the POS terminal;
• and
• a touchscreen, configured to simultaneously display details for the transaction in conjunction with the guest device, wherein said server has accessed said push notification device identifier to transmit a push notification to said guest device, and wherein said guest device has accepted said push notification and is executing a proprietary application that allows for simultaneous display of said details for the transaction;
• and
• said communication circuit, also configured to receive notification from said server that the transaction is complete, wherein transaction completion data was entered via said guest device and transmitted to said server, and wherein said server has completed the transaction.
