Assuming you would like a step-by-step guide on setting up Snapcash:
1. Open the Snapchat app and swipe right to open the Friends page, then tap the Add Friends button in the top-right corner.
2. In the search bar, type in Square Cash (without the quotes). Tap on the result to add Square as a friend on Snapchat.
3. Once you've added Square as a friend, send them a chat message asking them to set up Snapcash with you. Include your debit card number, expiration date, and CVV code in the message (you can find this information on the back of your card).
4. After you receive confirmation from Square that Snapcash is set up, you're ready to start using it! To send money via Snapcash, just enter an amount into a chat with someone and press the green Send button. A prompt will appear asking if you want to pay with Snapcash - select Yes to confirm.
5. That's it! The recipient will get a notification that they've received money, and they can link their own debit card to withdraw it from their account balance.
