General POS Software / Hardware Issues
I'm looking for answers to a few general questions regarding how point of sale (POS) software and hardware typically work in brick and mortar stores. I understand there will be many edge cases given the huge number of solutions, but I am looking for answers to the most common settings ...
So here it is: I understand that there are several standards for hardware interface standardization (OPOS, JavaPOS, UnifiedPOS). However, what is most common these days?
When scanning a credit or debit card, does the scanning device take over the processing of processing the card, or does it transfer it to the main POS terminal, which then connects to the processing service for processing?
Are there any software standards for major POS terminals?
How are product identifiers usually stored - barcode, ASIN, proprietary standard?
Thanks in advance!

UnifiedPOS , as the name suggests, seems to be the most universal standard. JavaPOS is , as you would expect, a Java-specific language and OPOS is WIN32 / COM, which suggests that it is an older standard.
OPOS, JavaPOS, and POS for .NET are based on the UnifiedPOS standard, and all seem to have widespread support. Thus, your choice comes down to which programming language you want to use to develop the platform.
Equipment written in the UnifiedPOS standard must work with any of these platforms. The UnifiedPOS Committee claims that 36 different edge service point types currently support the standard.
