IC Card IC Name : Venue and Date
Description : Selection of the Venue and Date for the Wedding.
My Task : Show the available venues to the Bride and Groom
Name of Other IC : Bride and Groom
Message to the Other IC : Please select venue and date according to the preference
Other Ic's Task : Select the venue according to the date available.
Here, we have to note that multiple messages can be passes back and forth, because the dates may not match for either the bride or the groom. It may also happen, that if it matches for them, the venue might not be available that day. So, the IC card should handle multiple messages.
