I have quickbooks 2016 Pro - desktop - so far apparently there is no chip reader available for use with a desktop.  have been using just a credit card "swiper" - had the one from QB but it quit working - bought another from Amazon - it worked sometimes, other times wouldn't work - now has quit working all together - can I buy a "swiper" from merchant services that will work with my desktop.  Are we the only business still using a desktop?
