There is many people who need help for this POS
I assume, that most of them already left the Scene, if they really needed a POS, and don't plan to depend on plain luck.
And professional Retail Shops, or even Shop Chains, would not use OpenCart for a POS System anyway, but depend on one of the real Software-PRO's.
But multiple attemps have been made, to 'realize' such Tools, possibly only to find out, that Earnings will not cover time and brainpower invested, required, even to only keep up with frequently changing OC Versions.
Still, some of the OC-related Software can still be found on the Web, at least, if one does not need to depend on others assistance. Most POS Names are listed on the image below. But don't expect much free
assistance here, if you run into a problem, POS is not a 'broadly familiar' thing !
One of the Sites is still (partly) active:
But they don't seem to care much about keeping their links in active state:
http://pos4opencart.com/shop/index.php? ... tion_id=12
http://pos4opencart.com/shop/index.php? ... tion_id=13
So, it's hard to guess, if it still pay's out, to take a chance...
Corrected links ... (some icons are missing also...

Demo Admin POS4Opencart STDplus : (latest free Download linked below)
Please note: I am not sure, wich OC Versions will be able to work with wich Extension.
POS4Opencart STDplus looks more like an OC v.1.5.x Code, and TheOnePOS-1.3.1-lt
like some earlier OC v.2.x Coding. Just to have this mentioned too.
