Method and system for encoding information into a bar code with different module size

摘要

Methods for generating and reading a two-dimensional barcode comprised of a number of data modules for storing a first encoded set of binary data and a second encoded set of binary data. The first set of binary data is encoded using a first data module size and the second set of binary data is encoded using a second data module size, wherein the first data module size is larger than the second data module size. Mail metering and verification systems for implementing the methods are also disclosed.
