Our payment processor has confirmed that they will still be able to process thru the POS application. For us, nothing is changing in that regard.  

However, my concern is if I will still be able to manually transfer data outside the "Financial Exchange" function, which is what I thought I did between the years 2018-2021.  We definitely continued to interface an unsupported version 12.0 for three years before upgrading to v.19. 

We use Enterprise Desktop, so THAT is where my new concern is:  Will I still be able to get that POS data into Enterprise?  I'm not sure yet.
