>>Another option is to use touch screens, which are fairly inexpensive and in general give users faster 'point and click' operation than a mouse. No extra programming is necessary. Most of our fast paced retail customers are using touch screens. They love them.

Just had to look at it, to see how many words would I recognize. Well, my grandmother used to say chikmezhe - that would be the drawer... harach used to be the Ottoman tax, so I figure it actually means just tax, and mushterija is still the word for customer (to differ from consumer). What's nakit? Means jewelry in Serbian, but that must be a freak accident, it's from verb "kititi", to decorate. "Kalem" means spool, but also graft (of fruit plants or roses - djul, eh? :), but that's probably unrelated too.

Nice design, BTW - buttons look really cool and more 3d than what the be-your-own-cashier machines in groceries here have.
