Q: What is OPOS?

OPOS (OLE for Retail POS) is a standard programming
interface definition for POS peripheral devices. It provides
hardware independence for the POS system developers and
integrators by defining for the POS application a common
interface for each type of POS peripheral. An additional
benefit of using OPOS is the ability to have from the retail
application a finer control over the scanner.
