And as for his YouTube content? “I’ll still probably be making vending machine videos — but I have thought about branching out into other businesses,” Ibanez says. Classic hustler mentality.

More machines have touch-screen shopping, and some companies are testing wireless technology to allow consumers to make a vending machine purchase with a mobile phone.
