I'm confused. Are you talking about the Square POS app? Or the Square Cash app? There is no account to share with anyone to receive payments via the Square POS app. You sell people stuff and swipe/tap/insert their card in a reader...or you type the information in manually and pay a higher processing fee for a 'card not present' transaction. But there's no e-mail address you can give out to have people send you money like PayPal.
I'm not familiar with the Square Cash app at all, so if you're referencing that...I'm not able to offer any clue there.
