System and method for sharing information using a machine-readable code on a mobile device

A non-transitory computer readable medium having stored thereon instructions which, when executed by one or more processors of one or more computers, causes the one or more processors to execute steps of a method for sharing information, the method comprising the steps of:

• displaying on a screen of a mobile device a first and second data field, wherein the first data field includes a machine-readable code and the second data field includes at least a first and second selectable visual indicia corresponding to information that is to be shared by a user of the mobile device;
• receiving a first input corresponding to a selection of the at least first selectable visual indicia by the user;
• visually distinguishing on the screen the at least first selectable visual indicia from the at least second selectable visual indicia;
• dynamically modifying in real-time the machine-readable code to include the information corresponding to the first selectable visual indicia;
• receiving a second input from the user, wherein the second input corresponds to the second selectable visual indicia;
• and
• dynamically modifying in real-time the machine-readable code to include the information corresponding to the second selectable visual indicia and, optionally, the first selectable visual indicia, wherein the machine-readable code includes a URI conforming to a URI standard set forth in RFC 2396, wherein the URI standard includes a domain portion and a parameter portion, wherein the parameter portion includes a URI-encoded serialized data object containing underlying data representative of the information corresponding to at least one of the first and second selectable visual indicia.
