Japan has an app called PayPay. It’s super popular and accepted almost everywhere now. I touched briefly on how this company grew by doing a lot of manual legwork by literally going to businesses and talking to them. Anyway … when you make a payment in the app, it audibly says “Pay Pay” in an excited tone. 

I find it fascinating that they chose this experience. It’s as if they wanted people nearby to hear the brand name while people are paying. 

Annoying or genius? You be the judge.
