… Here’s how it works: An employee signs up on the Earnin app and connects their bank account. Earnin infers the person’s pay cycle and debits their account the amount they’ve borrowed on their payday. Earnin charges no fees or interest; instead, it operates on a pay it forward revenue model some would balk at. Earnin users have the option to “tip” the app after each transaction and that tip, in turn, is used to fund the next user’s withdrawal. If a user tips more than Earnin thinks is reasonable for the given withdrawal, it will notify the user and give them the option to dial back the tip amount.
