Proximity based interactions via mobile devices

One or more non-transitory computer-readable media storing instructions thereon, wherein the instructions cause one or more processors to perform operations comprising:

• autonomously identifying, by server, one or more mobile devices in a proximity of a first mobile device that is associated with a potential payor of a gratuity;
• comparing, by the server, each potential payee associated with each of the one or more mobile devices with information associated with the potential payor;
• determining, by the server, that at least one potential payee is an appropriate potential payee based on a determination that the at least one potential payee is associated with a merchant in the proximity of the first mobile device;
• communicating, by the server, a notification to the first mobile device that at least one appropriate potential payee has been identified;
• causing, by the server, for each appropriate potential payee and not for any potential payee that is not determined to be the appropriate potential payee, a presentation of a face or biographical data of each appropriate potential payee of the gratuity that is logically associated with a respective identified mobile device, wherein the presentation is displayed on the first mobile device that is associated with the potential payor of the gratuity;
• and
• causing, the server, in response to an input received via a user interface of the first mobile device, to credit an account associated with a selected appropriate potential payee of the gratuity.

A system comprising:

• memory;
• and
• one or more processors coupled with the memory, the one or more processors configured to perform operations comprising:
• autonomously identifying, by server, one or more mobile devices in a proximity of a first mobile device that is associated with a potential payor of a gratuity;
• comparing, by the server, each potential payee associated with each of the one or more mobile devices with information associated with the potential payor;
• determining, by the server, that at least one potential payee is an appropriate potential payee based on a determination that the at least one potential payee is associated with a merchant in the proximity of the first mobile device;
• communicating, by the server, a notification to the first mobile device that at least one appropriate potential payee has been identified;
• causing, by the server, for each appropriate potential payee and not for any potential payee that is not determined to be the appropriate potential payee, a presentation of a face or biographical data of each appropriate potential payee of the gratuity that is logically associated with a respective identified mobile device, wherein the presentation is displayed on the first mobile device that is associated with the potential payor of the gratuity;
• and
• causing, the server, in response to an input received via a user interface of the first mobile device, to credit an account associated with a selected appropriate potential payee of the gratuity.
