Interactive image-based communication using image coding

A method comprising:

• causing, via a processor, a first image code presented on a first display of a mobile device to be captured via a first camera, wherein the first image code comprising first information comprising account information, wherein the processor is in communication with the first camera, wherein the mobile device includes a second camera and generates the first image code based on an encryption code of a plurality of encryption codes received from a data source along with a set of time period information instructing the mobile device to use the encryption code during a time period of a plurality of time periods, wherein the encryption code is associated with the account information during the time period, wherein the set of time period information is associated with the plurality of time periods;
• processing, via the processor, the first information such that a second image code is generated, wherein the second image code comprising second information formed responsive to the account information;
• causing, via the processor, the second image code to be presented on a second display such that the second camera captures the second information, wherein the processor is in communication with the second display;
• causing, via the processor, a third image code presented on the first display to be captured via the first camera, wherein the third image code comprising third information, wherein the third image code is generated locally at the mobile device;
• and
• processing, via the processor, the third information such that a point of entry device grants or denies an access based on the third information, wherein the processor is in communication with the point of entry device, wherein the first information, the second information, and the third information are different from each other in content.

A system comprising:

• a point of entry device including a gate, a first camera, and a first display;
• a mobile device including a processor, a second camera, and a second display, wherein the processor runs a logic that causes:
• the second display to present a first image code comprising first information such that the first camera captures the first information, wherein the first information comprises account information, wherein the processor generates the first image code based on an encryption code of a plurality of encryption codes received from a data source along with a set of time period information instructing the processor to use the encryption code during a time period of a plurality of time periods, wherein the encryption code is associated with the account information during the time period, wherein the set of time period information is associated with the plurality of time periods;
• the second camera to capture a second image code from the first display, wherein the second image code comprising second information, wherein the second information is generated based on the first information inclusive of the account information;
• the processor to decode the second information from second image code locally;
• the processor to process the second information locally such that a third image code is generated locally, wherein the third image code comprising third information and the second display to present the third image code comprising the third information such that the first camera captures the third information and the gate grants or denies an access based on the third information, wherein the first information, the second information, and the third information are different from each other in content.
