I am newbie into Point of sale software development, and by reviewing some pos software they mention that the program support barcode reader, but from what I know the barcode reader will take the responsibility of reading the barcode and generate string and it will just act as ordinary keyboard. So why it even need "support". Or am I missing something?
There are many functions and configurable features that have to do with symbologies, delays and special characters.
If a POS advertises that they support barcode readers, I would look more in-depth for a list of brands and what scanner functions you can turn on and off through the software.
What they are implying is that their software has incorporated the SDK for the brands of scanners they support and allows configuration of options through screens in the system and not just by scanning the barcodes in the scanner's manual.
If they advertise that they support barcode readers and do not interact with the scanner except as a simulated keyboard, then I would agree that this is misleading.
