The Bureau of Engraving and Printed got design info out to the makers of vending machines more than a year in advance, in an effort to ensure that machines would be able handle the new bills when they came out.
The current $20--the first of the US bills to feature color--started circulating in 2003. I expect any vending machines designed since then were designed to be software upgradable to handle new bills. Machines older than that (and I'm sure there's lots of them), may not have been designed to ever handle money except what there was when the machine was built.
