Machine readable code with portion analysis

A machine readable code transmitter employing a server computer comprising:

• a processor;
• and
• a computer readable medium coupled to the processor, wherein the computer readable medium comprises code executable by the processor for implementing a method comprising:
• receiving an authorization request message comprising an account identifier, wherein the account identifier is associated with a user,
• wherein the server computer is determined by a processor computer from information included with the authorization request message, and the processor computer received the authorization request message from an access device in a transaction;
• determining a machine readable code portion of a machine readable code based upon the transaction;
• and
• transmitting data representing the machine readable code portion to a communication device, wherein the communication device thereafter displays the machine readable code portion.

A communication device comprising:

• a processor;
• and
• a computer readable medium coupled to the processor, wherein the computer readable medium comprises code executable by the processor for implementing a method comprising:
• initiating a first transaction with an access device of a resource provider, thereby causing the access device to generate and transmit an authorization request message comprising an account identifier associated with a user operating the communication device,
• wherein the authorization request message is transmitted to a processor computer from the access device, and wherein the processor computer is determined by a server computer from information included with the authorization request message;
• receiving, from a machine readable code transmitter employing a server computer, a first machine readable code portion based upon the first transaction;
• receiving a second machine readable code portion associated with a second transaction;
• and
• displaying the first and second machine readable code portions at a same time, the first and second machine readable code portions form part of, but not an entire, machine readable code, and wherein the first and second machine readable code portions form at least part of a complete machine readable code for authorizing a third transaction.
