The point is the acquiring bank has to "splitit" and the acquiring bank doesnt need a patent - its part of the network if you invoke 'installment payment'.
This whole thing is really amusing - they basically have a patent on ....nothing (which is why it was rejected in Australia - see https://hotcopper.com.au/threads/patents.4671610/?get_post=true )

As for Visa - it represents something like 60% of all card payments globally - so doubtful they wouldnt be using it. Prospectus refers to Visa in any case.
Im quoting sources and facts > but if holders prefer hype, then thats ok - but facts wont change.
