Basically, i'm trying to figure out if you can add a software to run alongside an already installed POSs, that can also access the barcode scanner?
Does it depend on whom the POSs has been installed with?
Please help!
I'm pretty new in this area, but I know that UPOS has the concept of Sharable Devices, multiple apps can use the device in this case.
Some devices are sharable devices. An example is the keylock. A sharable device allows multiple Control instances to call its methods and access its properties. Also, it may deliver its events to multiple Controls. A sharable device may still limit access to some methods or properties to the Control that has claimed it, or it may deliver some events only to the Control that has claimed it.
