By now, it's a fairly well understood that bar codes have not been, and will not be, killed off by RFID or any other technology in the foreseeable future. However, many who acknowledge that bar codes (or at least optically readable symbologies) will be around for a while have assumed the status quo for bar code technology. Not true.
GS1 has begun investigating whether additional, existing, matrix symbologies should be certified for health care (and possibly other small space applications) and new symbologies are still being introduced to meet new needs or address old problems much more effectively.
For example, GS1 has been asked to consider the use of Aztec Code and QR Code for space constrained marking applications. Aztec Code and QR Code have finder pattern designs that are less sensitive to edge damage that might render the symbol unreadable, a limitation of Data Matrix.
