Did you work a cash register at one of your jobs? Then say that in your résumé and move on. Don’t try to make it sound more exciting than it really is.
If you try to fluff it up and make it sound “more businessy” or “more resume-friendly” than it is, the person reading the résumé will just roll her eyes. Maybe she’ll laugh at you, or call someone over and say “Hey, this guy worked a register and called it ‘Accounting for legal tender’! Ha ha!” We know when you’re trying to fool us, and we think it’s both funny and insulting.
Now, if your cash handling is a key component to your background, perhaps because you’re working to be a cashier at a casino, then by all means, play it up, by giving specifics: “Handled over $50,000 per shift with zero short/over”. That way you’re showing the scope of your responsibilities. But if you’re looking for a sysadmin position? Don’t bother.
A résumé is about telling a company about what you’ve done that will help them decide that you’re worth bringing in for an interview. Don’t try to BS us in the process.
