Compact protocol and solution for substantially offline messaging between portable consumer device and base device

摘要

A method for providing messaging between a portable device and base device is provided. The method includes communicating one or more message codes maintained in the portable device to the base device. The base device then composes a message for a user of the portable device using a dictionary of message codes. The message codes have corresponding message values, which are used to generate the message for the one or more message codes. The generated message is then provided to the user.
