摘要

The machine-readable pay code may be distributed to the payer device through acoustic stimuli, or as a result of voice or human based gesture actions. A user of the payer device may also participate in the financial transaction through the indirect control of a display by reading a unique machine-readable code unique to the display. Additional transaction details for the specific transaction may be received in the payer device through near field communication, or accessed at a later time when there is established connectivity to a mobile network.
