Abstract: A computing device for secure communications includes a communication interface, a transceiver, and a processor. The processor identifies an action to be completed by a third computing device operably connected to the computing device via the communication interface. The action is associated with data stored in the third computing device. In response to identifying the action, the processor transmits an identifier, obtained from the third computing device, to a second computing device using the transceiver; receives a second identifier from the second computing device using the transceiver; transmits the second identifier to the third computing device via the communication interface; and receives a confirmation of completion of the action from the third computing device via the communication interface.

Abstract: A method of electronically facilitating a commercial transaction can include displaying a first scannable code on a display of a user device, placing the user device adjacent to a scannable code reader device, scanning the first scannable code of the user device with the scannable code reader device. Further, the method can include displaying a second scannable code on the scannable code reader device, scanning the second scannable code with a camera on the user device, and displaying a digital payment scannable code to complete the commercial transaction.

Abstract: A method of electronically authenticating an electronic ticket upon entry to a venue can include displaying a first scannable code on a display of a user device, placing the user device adjacent to a scannable code reader device, scanning the first scannable code of the user device with the scannable code reader device, generating a second scannable code and displaying the second scannable code on the scannable code reader device, scanning the second scannable code with a camera on the user device, generating a user ticket code on the display of the user device, and displaying the user ticket code on the user device to gain admittance into the venue.
