There are good solutions out there. I&#x27;m currently working for a startup that&#x27;s doing iPad based POS.<p>Without trying to toot our horn, it&#x27;s a lot better than any of the legacy systems out there.<p>So no, there ins&#x27;t really a reason why there isn&#x27;t a solution except that nobody has made one yet (except for us and a couple of other tablet based POS systems).
