When dining out I regularly lament the fact that no one seems to have invented a hand held PDQ/POS terminal with a calculator or bill splitting on it. It seems like such a basic requirement of anyone taking payment in a restaurant.
But then the interfaces on PDQs seem poor generally (along with office telephones!) so I figure no suppliers are that interesting in making a difference for their customers! So analogue
But am I actually right? Are there PDQs with this feature?
