When you receive your first Square Cash payment, you’ll be asked to link a bank account or debit card, but guess no other verification.
If you want to keep some funds in your Cash app, you can cash out a custom amount or your can spend those funds right from your Cash prepaid card.
Square Cash personal accounts have sending and receiving limits.
When you receive more than $1000 in 30 days, we’ll ask you to verify your name, date of birth, and last 4 digits of your SSN to increase the receiving limit to amounts over $1000 per 30 days (in most states).
