System that facilitates making mobile payments to multi-function printer using proximity network and payment server

A method, comprising:

• coupling a multi-function printer to a mobile device via a proximity network interface;
• determining at the multi-function printer a workflow specified by a user of the mobile device;
• sending an ephemeral token associated with the workflow from the multi-function printer to the mobile user device, the mobile device using the ephemeral token to create a payment packet that is sent to a payment server which sends a receipt in response thereto;
• receiving the receipt at the multi-function printer from the mobile device;
• in response to receiving the receipt, obtaining a list of payments at the multi-function printer from the payment server;
• and
• performing the workflow via the multi-function printer based on validating the receipt against the list of payments.

A method comprising:

• connecting a multi-function printer to a mobile user device via a proximity network;
• determining, at the multi-function printer, a workflow of the multi-function printer specified by a user of the mobile device;
• receiving payment information associated with the workflow from the mobile user device at the multi-function printer, wherein the payment information is encrypted in a first packet;
• sending a payment request from the multi-function printer to a payment server, the payment request including the first packet and a second packet with a workflow identifier and payment amount encrypted therein;
• determining at the multi-function printer via the payment server that the payment server has authorized the payment, wherein the payment server authorizes the payment if the first and second packets agree on the payment and the workflow identifier;
• and
• performing the workflow in response to determining the payment gateway authorizes the payment.
