Item is listed as for parts or not working because I do not have a way to check if they work, they are in great condition.

Although untested, it can still serve as a valuable part for repairing or upgrading other similar credit card readers in the market. Hi, I dont know if they work.thats the reason they are listed for parts or not working maybe they work I really dont have a way to check them out.out of that they look in great condition.

As an untested device being sold for parts, it may have certain features that are not in working order. However, it still holds value for those seeking to repair or salvage components for their own projects.
